How to Flush Your Hot Water Heater
If you’re busy with home tasks, it’s easy to ignore the importance of flushing your hot water heater. In my own case, I had never considered doing so until Jeremy included it in his really useful house maintenance checklist. However, cleaning out your hot water heater on a regular basis is a vital duty. It is important to clean out the muck and mineral deposits that have accumulated in your hot water heater to ensure that it runs more effectively and that its life is prolonged, so saving you money in the long run.
However, fortunately, it turned out to be really simple.
I detailed the procedure as I went through, in case you find yourself in a similar situation.
Here’s how it’s done:
How Often Should You Flush Your Hot Water Heater?
While carrying out home duties, it is easy to ignore the need of flushing your hot water heater. In my own case, I had never considered doing so until Jeremy included it in his really useful house maintenance list. However, draining out your hot water heater on a regular basis is a critical duty to perform correctly. Remove the muck and mineral deposits that have accumulated in your hot water heater to make it function more efficiently and for a longer period of time, so saving you money over time.
However, it turned out to be really simple.
I chronicled the procedure as I went along in case you find yourself in a similar position.
It works like this:
How to Flush Your Hot Water Heater
Hot water heaters are available in two different configurations: gas and electric. Due to the fact that I have a gas hot water heater, following instructions will be specific to flushing a gas hot water heater. While there are some similarities between gas and electric, the most significant distinction is that with gas, you will be shutting off the gas to your appliance; with electric, you will be turning off the power to your appliance. 1. Turn the Thermostat on your hot water heater to the “Off” position.
- In most cases, the thermostat for a gas hot water heater may be found in the bottom of the tank.
- If you switch off your hot water heater and it’s an older type, you’ll have to re-light the pilot light, which might be a hassle.
- If you have a gas hot water heater, locate the gas pipe that runs from the tank to your thermostat and pilot light and switch the valve to the “off” setting.
- Turn it all the way off.
Fill a sink or tub with hot water by turning on the faucet.
As a result, you will be less likely to have a vacuum build in the pipes while draining the hot water tank.
Connect the garden hose to the drain spigot on the wall.
Depending on whether or not your hot water heater is located in the basement, you may require a portable pump in order to pump water from the basement to the first floor of your home.
Turn on the spigot and drain the water.
If your tank is clogged with silt, you may need to thoroughly drain it.
I decided to drain it anyhow.
Flush your hot water tankTo flush your hot water tank, just switch on the cold water tap that leads into your hot water tank.
This might take some time.
Here’s a photo of the water that was flowing out of my tank when I first started flushing the toilet: As you can see, there was still some silt (which can be seen at the bottom) pouring out of the hole.
Flushing should continue until there is very little or no sediment left in your water. Turn off the cold water faucet that feeds into your hot water tank and leave it shut.
Finishing Things Up
Following your satisfaction with the purity of your water, it’s time to return everything to their original state.

Boom. You’ve taken the time to flush your hot water heater. Make a note on your calendar to repeat the process in a year.
How to Flush a Water Heater
Boom. After flushing your hot water heater, you should be good to go! Put it in your calendar for next year so you don’t forget about it!
Have you cleansed your water heater in the last several months? This crucial task should be completed at least once a year in order to eliminate silt that has accumulated at the bottom of the tank. This is especially true if you reside in a hard-water location, which is common in the Midwest. Because it’s out of sight, it’s easy to forget about it, but accumulated sediment affects the heating effectiveness of your water heater, which results in higher energy bills.
- Female PVC trap adapter 1-1/4 in. x 1-1/2 in.
- 2″ brass nipple
- 24-in. piece of 1/2 in. I.D. vinyl tubing
- 3/4 in. MIP x 1/2 in. barb fitting
- 3/4 in. x 3-in. nipple
- Brass ball valve
- Brass elbow
- Dielectric nipple
- Garden hose adapter
- Shop vacuum adapter
- 1-1/4 in. x 1-1/2 in. female PVC trap adapter
If you haven’t cleansed your water heater before, or if you haven’t done so in a long time, you might be in for a nasty surprise in the shape of sediment buildup, which can limit the life of your heater significantly. A popping or rumbling sound emanating from your water heater is one symptom that you have an excessive accumulation of sediment. The sound you’re hearing is the sound of steam bubbles rising through the sludge. When sediment builds up in a gas water heater, it causes hot spots that can damage the tank and lead it to fail prematurely.
As a result, understanding how to drain and flush a water heater will pay dividends in the form of cheaper energy costs and a longer heater life.
Project step-by-step (8)
- A 1-1/2-inch PVC x 3/4-inch FIP adapter (A) is glued to the end of a female PVC trap adapter (B).
- Please keep in mind that this will allow you to attach your vacuum to 3/4-inch tubing. The barbed fitting (C) attaches to vinyl tubing with an inside diameter of 1/2 inch.
Drain Water Heater Liquid
- Shut off the water heater by turning off the gas or electricity. Make sure that the hot water faucet is running full blast for around 10 minutes to lessen the water temperature in the tank
- Otherwise, the water will boil. Closing the cold water valve at the top of the tank and connecting a garden hose to the existing drain valve and routing it to a floor drain are the first steps.
- Using a kitchen strainer to capture the silt will help prevent the sediment from clogging the floor drain.
- Make sure that a hot water faucet on an upstairs floor is turned on, as well as the water heater drain valve Wait until sediment jams the valve and causes flow to be reduced before flushing. Close the hot water faucet and the water heater drain valve on the second floor. Remove the temperature-pressure release valve and replace it with the vacuum adapter
- Then repeat the process. Connect the shop vacuum hose to the vacuum and turn it on
- Note: This creates suction in the tank, preventing you from getting drenched when you remove the old drain valve.

Remove the Old Valve
- By rotating the plastic nut below the knob, you may unscrew and remove the valve while exerting suction via the TPR port with a shop vacuum, and then replace it.
- The valve may be unscrewed and removed by rotating the plastic nut that is located beneath the knob while using a shop vacuum to apply suction through the TPR port
Assemble the New Valve
- In order to assemble all of the 3/4-inch fittings, you must first remove the handle from the ball valve
- A new drain valve made of a 3/4-inch full-port brass ball valve with threaded ends, a 3-inch x 3/4-inch galvanized nipple, and a 3/4-inch G.H. garden hose adapter (such as the BrassCraft/Plumbshop No. HU22-12-12TP) is an excellent solution.
- Removing the handle from the ball valve will enable you to assemble all of the 3/4-inch fittings. A new drain valve made of a 3/4-inch full-port brass ball valve with threaded ends, a 3-inch x 3/4-inch galvanized nipple, and a 3/4-inch G.H. garden hose adapter (such as the BrassCraft/Plumbshop No. HU22-12-12TP) is an excellent option.
Install the New Valve
- In order to use the new full-port valve, make sure it is closed. One end of the garden hose should be connected to the valve, and the other end should be directed into a colander put over the floor drain.
After you have flushed the water heater, remove the ball valve handle, especially if the water heater is in a location where people may stroll by and accidently hit the handle. Upon opening, hot water might be released, resulting in severe burns. In order to prevent it from falling out of the handle, twist knot it to the valve. Step 6: Organize your thoughts and feelings about the situation.
Flush the Tank
- Disconnect and flush the tank by removing the suction hose from the TPR port
- Advice from the experts: The majority of the silt will be flushed out through the full-port valve. To remove the remainder, open the cold water valve at the top of the tank in short bursts, blasting the water toward the drain until it runs clear.
The seventh step is to suction out the sediment.
- Remove the full-port valve and use a shop vacuum adaptor and 1/2-inch vinyl tubing to suction out any leftover silt from the system. Upon completion, close the ball valve and leave it in place, but remove the lever handle to avoid an inadvertent opening of the valve. Replace the TPR valve and blow-off tube, and then reinstall them.
Step 8: Refill the Water Heater with water.
- Fill the water heater with fresh water
- Turn on the gas or electric

Every homeowner understands the need of regularly cleaning and maintaining their systems and appliances.
The removal of silt from a water heater can extend its lifespan and increase its efficiency.
By removing sediment from your water heater, you may save money while also heating your water more quickly. More information on why you should flush sediment out of your tank may be found here. Learn more about how a water heater works so that you can better understand how to clean out your tank.
1. Turn the Water Heater Off
If you have an electric water heater, make sure the power switch is turned off before continuing. Ensure that your water heater is a gas heater, such as the one seen in the photo above, by setting your thermostat to “pilot.” This shuts down the heating element in your water heater, allowing the water to cool down as a result. Ensure that no one in your home is currently attempting to take a shower, wash dishes, or do a load of laundry before beginning this home repair chore.
2. Turn the Cold Water Valve Off
Close the cold water valve and turn it off. When cold water is introduced into the tank and dispenses with the hot water, the water heater circulates the hot water around your home. You may entirely empty your tank of water if you don’t have any cold water coming into it from outside. If you skip this step, you’ll wind up with water constantly flowing into the tank and down the drain, which might result in a significant increase in your monthly water bill.
3. Let the water cool.
Don’t dump scorching hot water down the drain. Allow the tank to cool after the heating components have been turned off. Some bigger water heater tanks might take up to two hours to complete the process.
4. Attach a drain or garden hose to the drain valve on the side of the tank
Drain your water heater by connecting a hose to the drain valve located on the side of the unit. Make certain that the hose is properly screwed on, otherwise you may experience leaks when you drain your water heater tank from the faucet.
5. Place the end of the hose in a bucket or drain.
Don’t let your house flood! Make sure to place the hose’s end in a heat-resistant pail or down a drain when you’re finished. Before you begin emptying the water heater, check to be sure that your drain will not overflow while doing so.
6. Turn on a faucet (or two)
The use of faucets around your house might help prevent a vacuum from accumulating inside your plumbing system. Turn on the “hot” setting on your faucets and leave them running. Due to the fact that you have shut off the cold water valve to your water heater, there will be little or no warm water displaced through them.
7. Start draining the tank by turning on the drain valve.
Turn the valve on carefully with a flathead screwdriver, making sure there are no leaks and that the bucket or drain you are emptying the water into is not going to overflow while doing so.
8. After the water heater tank has finished draining the sediment, turn the drain valve off, remove the hose, turn the cold water valve on, and turn the heating elements in the water heater back on.
You are almost through with your water heater cleanup once you have thoroughly emptied it and removed all of the debris from the tank. In order to refill your tank, close the drain valve and remove the hose from the tank. Turn the cold water valve back on and the heating elements back on by turning the knobs on the thermostat. Check to see that your faucets are still turned on, and after the water is flowing normally again, turn them off. You’ll need to wait around 30 minutes before checking for hot water.

How to Flush Your Water Heater
Water heaters can lose their efficiency over time, resulting in greater heating costs as well as increased water bill costs. The silt that has accumulated in the tank is the source of their decreased efficiency since it is obstructing heat transfer and absorbing some heat at the same time. It is also possible that this sediment will cause harm to your water heater as well as obstructions in your water lines. An easy solution to this problem is to do a simple flush of your water heater. Most experts advocate having this done once a year at the very least.
Check with your manufacturer’s guarantee about maintenance to ensure that completing the maintenance yourself will not violate your warranty.
Steps to flush the water heater
Close or reduce the heater’s heating system or gas supply to prevent the water heater from going on and heating an empty tank of water. Setting your gas water heater’s thermostat to “off,” “pilot,” or “vacation mode” is one option; but, if you have an older system, it may be necessary to cut off the gas to the water heater as well as turn off the water heater itself. In certain older gas water heaters, if the gas has been turned off, you may need to relight the pilot light, and you should be familiar with how to do so and where it is situated before doing so.
- If there isn’t a switch or unplug option, you may have to turn it off with a circuit breaker if there isn’t another means to stop the flow of energy to the water heater.
- The main water valve to the house in some residences; in others, a shutdown valve near the water heater may be used instead.
- Connect a garden hose to the tank’s drain spigot, which is located towards the bottom of the tank.
- Place the other end of the hose in a location that is capable of handling the volume of water and the heat generated by the currently hot water in the water heater tank, if necessary.
- When you have determined that the water temperature is cold enough, repeat the previous procedure and switch off the water supply to the heater to complete the process.
- Allowing the tank to empty through the hose is accomplished by opening the drain valve.
If you don’t hear any water running and you don’t see any water draining from the end of the hose, you may have something blocking the air from flowing, such as a backflow preventer, or sediment has clogged the drain, and you will need to open the pressure release valve to allow air into the system to work properly.
Most Check the hose to make sure there isn’t any leakage along the way, and that the other end is still draining at the location you’ve picked, and that the water draining isn’t going to overflow the draining area after you’re finished.
At the end of the draining process, you want the water to be completely clear or mainly clear.
It may be necessary to turn on the water for approximately 15 seconds, then turn off the water and wait for a few minutes before repeating the process a few times to entirely remove any silt that has become lodged on the interior of the drain.
Observe the water draining to ensure that all sediment has been removed and that the water being drained is free of obstructions. When you have done flushing the system, turn off the water supply to the tank.
Now that the system is cleaned out, it’s time to put everything back:
- Close the drain valve and take the hose out of the system. Re-open and close the pressure valve (if you already opened it
- If not, double-check that it is still closed)
- Restart the water heater by turning the water back on. Open all of the hot water taps in the house to confirm that the water is flowing and that there is no trapped air. The water may appear cloudy at first, but wait until the silt has disappeared. The faucet should be turned off after the water is clear. Turn on the heating source, which may entail re-igniting the pilot light if the water heater is a gas model and the pilot has gone out. Make careful you only turn it on when the tank is completely full. It is dangerous to turn on an electric water heater while the tank is not completely filled because the heating element will burn out
Removing the hose and closing the drain valve Ensure that you have closed the pressure valve (if you have already done so, double-check that it is closed). Replacing the water heater’s supply with clean water Ensure that all of the hot water taps in the house are operational and that there is no trapped air. If you notice sediment coming from the faucets, simply wait until the water becomes clear. The faucet should be shut off after the water is clear. If you have a gas water heater that has blown out the pilot light, you will need to re-ignite the pilot light to get it going again.
Using an electric water heater without having a full tank will result in the heating element being destroyed.
How to Flush Your Water Heater – PlumbingSupply.com
By cleaning out your water heater, you may improve the efficiency and extend the life of your water heater. In particular, if you do not have a water filter on the incoming line of your house’s water supply, this is critical to remember. Because sediment in the cold water entering the water heater is heavier than the water, any sediment will fall to the bottom of the water heater and accumulate there. In many situations, the water heater actually serves as a filter for the hot water lines in your home, which is something it was not intended to accomplish in the first place.
- However, even though water enters the water heater from the top of the tank, there is a tube (known as the water heater dip tube) that causes the water to flow down to the bottom of the container.
- The dip tube, on the other hand, also pushes any sediment present in the cold water to settle to the bottom of the tank.
- It has been shown that sediment at the bottom of a gas water heater tank can actually function as an insulator between the burner and the water it is heating.
- It is possible for the bottom element of an electric water heater to become buried in silt, causing it to work more harder than necessary and eventually fail.
- The following should be noted: If you have an older gas water heater and have never flushed it before, flushing it may not be the best option.
Flushing out the tank could eliminate silt that is sealing a leak, which could cause much worse difficulties in the future. If you are at all confused about whether or not you should do a water heater flush, you should get advice from a qualified plumbing technician.
How do I flush my water heater?
Although flushing your water heater is a simple procedure, there is a high danger of harm due to contact with extremely hot water and surfaces. Please keep this in mind: Prior to commencing, please take all required steps to protect yourself and others, or hire/consult with a plumbing specialist. Additionally, please keep in mind that these instructions are generic in nature and are supplied solely for the convenience of our clients. PlumbingSupply.com® bears no responsibility for your actions in following these instructions.
- The first step is to switch off the electricity to your water heater at the breaker box.
- To conserve energy, bring the thermostat down to the vacation mode setting (or as low as it will go without completely shutting down your gas water heater).
- This can be accomplished by either waiting for the heater to cool down for a few hours or by having someone take a shower, do laundry, or wash some dishes at this time, causing all of the hot water to be used up (after all, you already paid to heat it!) and replaced by cold water.
- Removing the cold water supply valve from the water heater – this valve is often positioned at the top of the water heater’s inlet side, on the INLET side of the water heater.
- It is important to note that the hose outlet must remain lower than the amount of water in the tank in order for the water to properly drain out of the tank.
- If you have children, pets, plants, or bushes, you should position the other end of the hose in a safe location where hot water will not be harmful to them.
- Alternatively, a water heater drain pump can be used to expedite the procedure.
This is far faster than waiting for the water heater to drain naturally.
(or the hot side of any faucet close to your water heater).
Step 6.Now, return to the water heater drain valve and slowly open it until it is completely open, as shown.
The water coming out of the water heater can be allowed to drain into a clean bucket to see how much sediment is being flushed out.
If you are using a pump, turn it off and seal the drain valve once the water heater has been completely emptied.
This can assist in dislodging any more sediment that may be present in the bottom of the water heater.
Make a visual inspection of the drain water to see whether there is still material present or whether the water is clean.
If there is still some sediment in the water, repeat Steps 7 and 8.
Step 10.While the tank is empty, it may be a good idea to inspect your anode rod as well as your temperature and pressure (T P) relief valve (if applicable).
We also recommend that you remove the T P valve and check it for probable corrosion caused by particular water conditions, and that you replace it if required.
The water heater tank should be filled when you are ready to replenish it.
Check to see that the drain is completely closed and that it is not leaking.
Using a funnel, remove any debris that has accumulated in the drain valve and turn off the cold water supply at the top of the water heater.
Take note that if the drain valve is not operating correctly, it may also be necessary to replace it.
In order to determine the length of the pipe nipple, consider the amount of insulation that is utilized between the water heater tank and the decorative outside cover.
Step number twelve.
Make sure you turn on a few more faucets (on the hot side) in the house and leave them running until the water is flowing freely there as well.
Following your confirmation that all of the air has been sucked out of the water lines and the water heater, you can restart the water heater and begin heating the water once more.
If your water heater is powered by natural gas or propane, simply turn the thermostat back up to the desired temperature setting once more.
This material is intended to be general in nature and may not be applicable to all applications.

How Do I Flush My Water Heater and How Often Should I Drain It?
Thank you for visiting the Direct Energy series, “Take Charge of Your Home!” While hiring a professional to do household maintenance may provide convenience and peace of mind, many of these tasks may be completed by the homeowner without the need for specific tools or knowledge. And, in the process, you’ll save money, learn more about how your house operates, and experience a sense of satisfaction from completing a well-executed DIY project! You may take your water heater for granted, but it is one of those items that is simple to overlook.
- It’s possible that you only think about it when something goes wrong.
- This is especially true for tankless water heaters.
- The most effective strategy to safeguard your investment is to have your water heater serviced by a certified plumber on a yearly basis.
- In contrast, the last step – cleansing the tank — is something you may want to do on a regular basis, perhaps once every few months, depending on the mineral level of your local water supply.
Should I Drain My Water Heater Periodically?
Flushing out the lime and other particles in the water heater tank on a regular basis helps to increase the efficiency and longevity of the heater. Sediment can build up and calcify in water heaters that have been ignored, making it difficult to clean out. Eventually, this can get so severe that the entire unit may have to be replaced. However, by flushing your tank on a regular basis, you can avoid silt from causing difficulties. – Mineral content is present in all water to varying degrees. Because limestone is abundant under the surface of the groundwater, if you live in a location with a lot of limestone beneath the groundwater will pick up calcium and magnesium deposits, resulting in “hard” water.
When using natural gas heaters, it is possible to have uneven heating on the tank, which might lead to leaks over time.
In addition, silt accumulation might jam the drain valve in any case.
When Do I Want to Flush My Hot Water Heater?
For the most part, homeowners should clean their water heaters every six months or so; however, if you have particularly hard water, you may want to flush it more frequently.
Depending on the mineral level of your local water supply, it may be essential to flush your hot water heater as frequently as every few months or even more frequently.
Before You Begin a Water Heater Flush
You must first figure out how to switch off your gas water heater before you can begin draining the tank. It’s possible that a vacation location will do the trick. It’s also a good idea to find out whether the pilot light has to be turned on manually. In this case, the original owner’s handbook is the greatest source of information, because pilot lighting processes differ from one model to another. If you don’t have a handbook, search on the water heater’s label for the manufacturer’s name and model number, and then try to get the manual online using those details.
How to Flush Your Water Heater
Following the completion of your calculations, it’s time to do the flushing procedure.
- Step 1: Shut off the cold water supply to your water heater and remove the tank from the tank. Depending on the age of your home, you may need to cut off the water where the main water supply line enters your property. A shut-off valve for the water supply should be installed between your main supply line and the water softener
- Otherwise, the water will not be softened properly. Step 2: Turn off or lower the temperature of the water heater thermostat. Some water heaters are equipped with a “vacation” setting. In order to avoid the heater turning on once all of the water has been drained out, especially for natural gas heaters, it is best to avoid doing so since heating it without water might cause damage to the tank. Additionally, before continuing, you should turn off the gas supply valve. Step 3: Connect a garden hose to the drain valve on the tank, which is located towards the bottom of the heater. The other end of the hose should be connected to a drain or to a safe location outside the house. In the event that you want to let the water drain outdoors, make certain that it is far enough away from your foundation so that it does not run into your home’s crawl area. Also, keep it away from bushes or other landscaping. In order to avoid dealing with hot water altogether, switch off the water heater at the end of each day to allow it to cool overnight before draining it, or just run your hot water tap for several minutes before getting started
- Step 4: Open all of the hot water faucets. This will allow the water to drain from the tank more quickly. Put another way, it has the same effect as placing your finger tip on the end of a soda straw and then raising out of a drink. The vacuum maintains the liquid locked within until you remove your finger from the vacuum. Step 5: Open the drain valve on the water heater and let the tank to empty. Remember to keep an eye on the water as it pours out of the hose to keep an eye on how much sediment is coming through. Check that the water is flowing in the direction you want it to, and keep any young children or curious dogs from getting too close. If you open the drain valve and no water comes out, it’s possible that sediment has clogged the valve. In this case, you’ll need to open the temperature pressure release valve to release pressure from the tank and drain any water that has accumulated in the hot water pipes downstream from the water heater. Next, use a wet/dry vacuum to remove part of the obstruction from the drain valve — at the very least enough to begin the water flowing again. Wearing gloves and being careful not to get sprayed with hot water are recommended. If the obstruction is severe enough that it will not budge, remove the temperature pressure release valve and suck out the water with the wet/dry vac before replacing the drain valve
- If the blockage is not severe enough to budge, replace the drain valve. Step 6:After the tank has been drained, switch on the cold water supply to assist rinse away any sediment that may have accumulated at the bottom of the tank during the draining process. After a few minutes, check the end of the line to make sure it’s clear and then switch off the water supply to the house. As a test, gather a glass of water from the drain hose after about one minute of flushing, and then turn off the water supply to the toilet and sink. Wait a few minutes to check whether sediment begins to settle at the bottom of the glass, and if it does, or if the water has become coloured, repeat the process once again. 7. Disconnect the hose from the drain valve and use a wet/dry vacuum to remove any silt that has accumulated around the hole. 8. As a result, it will not clog the valve when you turn it off. A little won’t hurt, but you want to make sure there’s enough space around the valve to prevent it from leaking. Reconnect the cold water supply once you’ve finished shutting down the drain valve. Step 8: Keep the hot water faucets open until the water starts to come out of them. Step 9: This will prevent any trapped air from accumulating. Don’t be startled if you notice rust or sediment coming out of the drain in the beginning. It will be safe to turn off the faucets once the water has cleared, which will normally take around a minute. Step 9: Adjust the water heater’s thermostat to the temperature you want it to be. You should also restart the pilot light on your gas water heater if it is equipped with one. To do so, reopen your gas supply valve and follow the manufacturer’s instructions on how to do so. The time it takes to fill the tank should be between 15 and 20 minutes, while the actual time depends on the size of your water heater, its overall efficiency and whether it’s powered by natural gas or electricity.
How Do I Drain My Tankless Water Heater?
However, tankless water heaters are equally subject to harm from mineral silt, as stated above for traditional tank water heaters. To flush tankless water heater technology, an entirely separate procedure must be followed, and a pump is necessary to circulate water throughout the system. Tankless water heater flush kits with thorough instructions can be found at most hardware stores for a reasonable price. With an electricity plan from Direct Energy, you can see how your do-it-yourself home renovation tasks may help you save money on your energy bills.

Water Heater Flush: How To Do It Safely and Easily
Your water heater is responsible for delivering all of the necessary hot water to your home when you require it. You may only understand how crucial a piece of equipment is when it is not functioning properly or is backed up in some way. In order to guarantee that your water heater is operating at peak performance, you must ensure that it is thoroughly flushed and cleaned. For the purpose of assisting you in understanding the fundamentals of water heater flushing, we will first discuss why it is so important and how frequently you should perform it.
Why Do You Need to Do a Hot Water Heater Flush?
Water heaters begin to acquire silt and accumulation that is naturally contained in the water supply over lengthy periods of time of usage. Sediment can accumulate in the heater and clump together, resulting in decreased efficiency or damage to the device, depending on the circumstances. When it comes to water heaters in Phoenix, where the water is extremely sediment-rich, this is a regular occurrence. When you flush out your heater, you are preventing excessive sediment building and ensuring that you are able to use the unit more efficiently while experiencing less fear about failure.
Water Heater Flush Cost
As you’ll see, a water heater flush is really inexpensive when you consider that it can be completed in a matter of minutes by following a few simple procedures.
How Frequently Should You Do a Hot Water Heater Flush?
After all, a water heater flush is completely free when you consider that it can be completed in a matter of minutes by following a few simple instructions.
Steps for Performing a Water Heater Cleanout/Flush
Your heater, like any other item in your home, will require some level of electrical power to operate properly. Depending on your unit, you may only need to complete one of these procedures during a water heater flush, or you may need to complete all of them. By turning off your gas, you can assure that the machine is not getting any gas and will not overheat or leak as a result. In most cases, turning off the electricity to your unit may be accomplished through your circuit breaker, which should include a switch labeled for the heater.
Keeping this step in mind will help to provide a safe working environment for whoever is responsible for finishing the flush.
Open a Hot Water Faucet
Your heater, like any other equipment in your home, will require some level of electrical power to function properly. If your water heater has to be flushed, you may just need to perform one of these procedures, or you may need to perform many. It is important to turn off your gas in order to guarantee that your unit does not get any gas and does not heat up or leak. In most cases, turning off the electricity to your unit may be accomplished through your circuit breaker, which should include a switch labeled for the heater.
The completion of the flush should be done with care to create a safe working environment for everyone involved.
Turn Off the Cold Water Valve
Your heater will require some power to operate, just like any other item in your home. Depending on your unit, you may only need to complete one of these procedures during a water heater flush, or you may need to complete many. If you turn off your gas, you will assure that the device does not get any gas and will not overheat or leak. Cutting the electricity to your unit is normally accomplished through your circuit breaker, which should include a switch labeled for the heater. As you work on the equipment, this will help to avoid any electrical problems from occurring.
Connect a Hose to the Heater
Find the location of your spigot as the next step. This will be located at the bottom of the unit and will seem to be a standard hose faucet in appearance. You may want to set a bucket below this before proceeding with the rest of the project because it may begin to drip as soon as the lid is removed. It is necessary to locate a garden hose that can be screwed onto this spigot since this is the most convenient method of draining the system. If your water heater is located higher up in your home, gravity should be able to facilitate the flow of water.
If the unit is located in your basement, a pump may be required to assist in the removal of the water from the unit. Make certain that the hose’s end is placed in some form of pail or containment area to prevent it from spilling everywhere.
Water Heater Flush for Sediment: Drain the Tank
It is at this point that you may begin draining the unit by turning the faucet to which the hose has been connected. It is possible to see the circumstances that your heater may be encountering when the water drains out of the tank during this period of time. If the water is largely clear and typical in appearance, it is likely that your water heater is in good working order. Water that is deeper in color and that contains silt, on the other hand, might be a much greater problem. The inside of the tank might be in far worse shape than you can remedy with a simple water heater flush for sediment if you are emptying the tank and a large amount of solid material is coming out of the tank.
This step will be skipped if you are flushing a tankless electric water heater, which is the most common scenario.
Flush the System
Now that the water has been removed from the system, you will begin the process of flushing the unit. Keep in mind that you already switched off the cold-water spigot. This is what you will be turning back on in order to allow the new water to clean out the system properly. It is recommended that you drain the old bucket and thoroughly inspect it for sediment before refilling it with the fresh cleansed water. Remove the tank’s fill valve and flush it for a few minutes until the water pouring out seems clean and typical.
Always remember to switch off the cold-water supply before unhooking the hose and removing the bucket from the sink.
Reactivate Power and Gas
Now that the water has been drained from the system, you will proceed to flush the unit thoroughly with a pressure washer. Keep in mind that you have previously switched off the cold-water spigot. This is what you will be turning back on in order to allow the new water to clean out the system once again. The old bucket should be thoroughly cleaned and checked for sediment before being refilled with the fresh flushing water, according to the manufacturer. Flush your water tank for a couple of minutes or until the water flowing out seems clear and normal.
Always remember to switch off the cold-water supply before unhooking the hose and removing the bucket from the faucet.
Congratulations! This means that you have done all of the necessary procedures to cleanse your water heater in a reasonably short period of time. Now that you have a better understanding of the procedure, you will be better prepared the next time your heater requires flushing. The time spent flushing your heater will guarantee that it operates at peak performance and that it serves you for many years to come.

Frequently Asked Questions
It is recommended that you flush your water heater at least once a year, especially if you reside in a region with hard water and do not have a water softener. If your softener is in good working order, you can get away with flushing it once every couple of years, but flushing it more regularly won’t hurt.
How much does it cost to flush a water heater?
If you’re not sure in your ability to complete the task yourself, plan to pay around $100. When you consider how detrimental sediment may be to your water heater, this is a relatively insignificant expenditure.
What happens if you don’t flush your water heater?
If you fail to clean your water heater on a regular basis, sediment can accumulate in the tank and cause problems such as clogged drain lines.
How long does it take to flush a water heater?
While your first flush may take a little longer than usual, you’ll soon be able to complete the entire procedure in under an hour and a half.
How To Clean A Water Heater The Simple Way
If you maintain your water heater properly, there is no reason why it shouldn’t survive for more than a decade or more. Knowing how to clean a water heater is one of the most important skills to have in order to do this. Our goal with this essay is to provide a comprehensive walkthrough of the process of cleaning your water heater, regardless of its make or model.
How To Clean Your Water Heater: The Basics
If you’ve read our article on drinking tap water in Phoenix, you’ll know that the water that arrives at your house in Arizona (or any other state in the United States, for that matter) includes silt, minerals, and chemicals. In the course of time, these impurities might accumulate in your water heater, causing it to operate inefficiently. Inefficiencies such as inconsistent heating, an element that fails to stay lighted, and a blocked drain valve are all examples of inefficiencies. All of these will result in bills that are greater than planned.
The most effective technique to avoid this is to flush the system on a regular basis.
How Often Should You Flush Your Water Heater?
At the absolute least, you’ll want to flush the system once a year, if not more frequently. However, it is dependent on the composition of your local water supply as well as the equipment you have in your house. If you want to know more about the drinking water in your region, contact the Environmental Protection Agency (EPA). If you have a high-efficiency water softener installed, your heater may not need to be flushed as frequently since the softener will lower the amount of sediment in the water.
As a result, if you do not have a water softener installed, you may want to flush the heater as frequently as once or twice a month or two in order to prevent problems.
Signs It’s Time To Flush Your Water Heater
Water heater flushing on a regular basis is a successful technique, but it is also beneficial to be aware of the warning signals that suggest a flush is necessary in order to avoid costly repairs later on.
Here’s a brief review on what each of these indications means.
You Can’t Get Hot Water
If you are having trouble getting hot water from your heater, it is possible that sediment has accumulated within it to the point where it is either preventing the element from lighting or stopping the heat from passing to your water. Regardless of the situation, this is a hint that you need to flush the heating system.
Your Water Heater Is Making Strange Sounds
It is possible that silt can cluster together and create calcified stones that will smash against the sides of your water heater in areas where water is very harsh. This is a warning indication that you should flush the heater before the stones grow to such a size that they choke the drain line.
Your Water Smells Funny
It is possible that silt can cluster together and create calcified stones that will smash against the sides of your water heater in areas where water is especially hard. You should flush the heater immediately if you see this happening, since these stones will grow in size and eventually choke the pipe.
How To Clean Your Hot Water Heater: The Process
When cleaning your water heater, you will need to open many taps around your home and allow the water to drain entirely out of the tank. This is a necessary part of the process. Cleaning your hot water heater is actually pretty simple if you follow the correct procedures. You’ll discover that these procedures become second nature to you as time goes on.
Step1: Prepare The Heater For Flushing
Before you do anything else, be sure that the thermostat on your water heater is turned off. For many tanks, merely switching to “Pilot” mode will suffice to get the desired results. As a result, you will not have to go through the hassle of reactivating the pilot light, which is a simple but time-consuming task. You will also avoid the need to turn off the gas if you follow this procedure. It will be necessary to turn off the electricity to your water heater if you have one. The proper switch will be located on the device.
The valve for this operation is normally found on top of the heater, which makes sense.
Step2: Open The Hot Water Faucets In Your Home
This will aid in the drainage of the tank. If you do not complete this step, a vacuum will build in your tank, which will keep the water trapped within. It’s a strange physics effect, similar to how water remains caught in a straw if you maintain your finger on the tip of the straw while drinking.
Step3: Connect A Hose To Your Tank’s Drain Valve
The drain valve should be situated near the bottom of the tank, preferably on the side. In order to avoid damaging your home’s foundation, you’ll want this hose to either lead into a very large container or (ideally) to the outside and away from it. If you use a little bucket, you run the chance of flooding your basement or the area where the tank is located, which is not ideal. If your basement has a drain, you may be able to divert the water to it by placing the other end of your hose near the drain and directing it there.
Step4: Open The Drain Valve And Let The Tank Empty
Depending on how much sediment has accumulated in your tank, you may be able to see bits of sediment being discharged from it as they pass through.
With increased frequency of cleaning, you’ll be able to determine whether or not you’re maintaining a high level of consistency based on the quantity of sediment that comes out.
Not Getting Any Water Out Of The Tank? Try This!
You will not see any flow if you open the drain valve when there has been an excessive buildup of silt in the tank, which has clogged the drain valve. To correct the situation, use a wet/dry shop vacuum to remove the obstruction. The majority of the time, this will enough. If it does not, the situation may necessitate the involvement of a professional.
Step5: Reactivate The Cold Water Supply
Before you unplug your hose from the drain valve, be sure the cold water supply has been reactivated. This water will aid in the dislodgmentation of any further sediment that may have accumulated in your tank. Continue to allow for a few minutes of drainage until the water escaping from the hose is clean. (Optional) After that, switch off the cold water supply one more time.
Step6: Shut The Drain Valve Off
After you have disconnected the garden hose from the drain valve, turn the valve back on before turning on the cold water supply.
Step7: Close The Faucets After A Minute Or So
During the refilling process of your water heater’s tank, you may notice that discolored water is coming out of your faucets. If you wait a minute or two, this should be resolved. Once this has occurred, you may turn off the faucets.
Step8: Return Your Water Heater To Its Ready State
During the refilling process of your water heater’s tank, you may notice that coloured water is leaking from your taps. This should clean up after a minute or two. You will be able to turn off the faucets when this has occurred.
How To Clean A Hot Water Heater With Vinegar
You may need to use vinegar to cut through sediment accumulation if you suspect that your water heater has become seriously clogged with sediment. As far as how to clean a hot water heater with vinegar is concerned, the procedure is simply a few steps longer than what we previously described in detail. Before you proceed with the actions outlined above, do the following.
Remove The Anode Rod
Please refer to your tank’s owner’s handbook for the specific procedure to be followed. In most cases, a recessed bolt will require the use of a wrench to be unfastened.
Use A Funnel To Place Vinegar Inside The Tank
When you remove the anode rod, you will see a hole in the area where it was previously located. This is the location where the funnel should be placed. Fill the tank with no more than four gallons of vinegar after passing it through this funnel.
Replace The Anode Rod And Activate The Cold Water Supply
Reinstall the anode rod and turn on the cold water supply again. This will cause the tank to fill up with water again. Make sure to let the tank remain with the vinegar-infused water for the whole 24-hour period. During that time, the acidity of the vinegar will begin to work its way through the sediment.
Go Through Steps1 through8
To completely remove the vinegar (as well as any sediment that should have dissolved) from your tank, follow the instructions in steps 1 through 8 to the letter.
How To Clean A Tankless Water Heater
The fact that your water heater does not have a tank does not rule out the possibility of silt and minerals accumulating inside it over time. Essentially, a tankless heater does not store water and instead heats it on demand, as the name suggests.
As a result, becoming familiar with the process of pumping water into the system and then directing it out is essential to knowing how to clean a tankless water heater. The following are the steps to follow in order to do this correctly.
Step1: Switch The Power And Gas Off
To begin, turn off the electricity and gas (if your tankless heater is powered by gas).
Step2: Remove The Unit’s Panel And Test The Electricity
It is possible to detect whether you have correctly unplugged the electricity from the tankless water heater by using a no-contact electrical tester. This is a safety measure in case you accidentally turned off the wrong switch on your circuit breaker. It will alert you if you have done so. Once you are positive that the electricity has been turned off, go to the following step.
Step3: Turn Off The Water Supply
Shut down the water supply line that runs directly into your tankless heater.
Step4: Connect The Hoses
In contrast to a traditional water heater with a tank, you’ll have to actually bring water into your tankless heater as part of the cleansing process. That is why you will require two hoses. There are two connections: one links the unit to a pump (which pumps water into it) and another connects the unit to an isolation valve (catching the water as it expelled from the tank after making its way through).
Step5: Prepare A Five-Gallon Bucket With Your Pump And Hose
Prepare the vinegar by filling a five-gallon bucket halfway with vinegar and placing your pump and the open end of your second hose inside.
Step6: Let The Pump Run For An Hour
Turn on the pump and let it running continuously for an hour. The pump will circulate the vinegar through your tankless heater in a closed loop configuration. Hopefully, the steady flow (together with the acidity of the vinegar) will be powerful enough to wear away at any built-up sediment in your heater.
Step7: Remove The Pump And Activate The Cold Water Supply
You should now be able to leave the end of your second hose in the five-gallon bucket, which should be completely empty of any vinegar. Before turning off the cold water supply, let the cold water run through the system and into the bucket for about five minutes before turning it off.
Step8: Return Your Tankless Heater To Its Operational State
Disconnecting the hoses, replacing the panel, and reactivating the water supply valves are all steps in this process. The final step should be to re-establish electrical power to the device.
How To Clean Out Your Water Heater: Conclusion
By the end of this article, you should have gained an understanding of the fact that knowing how to clean out your water heater does not involve any specialist knowledge of the system. You should be able to do this task without difficulty if you follow the procedures outlined above. To summarize, let’s take a look at some of the specific considerations you’ll need to make based on the sort of water heater you have.
How To Clean An Electric Water Heater: Special Considerations
The procedure for cleaning an electric water heater is much less complicated than the procedure for cleaning a gas water heater. Because everything is powered by electricity, you won’t have to relight the pilot light when you’re finished with it.
How To Clean A Gas Water Heater: Special Considerations
As far as the proper way to clean a gas water heater is concerned, there are two important aspects to keep in mind. Before beginning the operation, you must turn off the gas valves in the house. Because turning off the thermostat will deactivate it, you will also need to relight the pilot light after you are finished.
