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?
It is recommended that you cleanse your hot water heater every one to three years, depending on your model. Really, it’s such a simple job that it wouldn’t be a hassle to complete it at least once a year.
How to Flush Your Hot Water Heater
It is recommended that you flush your hot water heater every one to three years, depending on your particular model. To be honest, it’s such a simple job that doing it at least once a year wouldn’t be too much of an inconvenience.
Finishing Things Up
It is recommended that you flush your hot water heater once every one to three years, depending on your model. Really, the work is so simple that doing it at least once a year would not be a hassle.
- Disconnect the drainage spigot and the hose from the drain
- Turn off the water supply to your sink or tub that you had switched on at the start of the process. To begin, turn on the cold water tap that feeds your hot water heater. To get the air out of the system, turn on the hot water faucet in a sink or bathtub for a few minutes. At this point, you should be able to get cold water out of the faucet. To turn it off, press the button. Restart your hot water heater if you have accidentally turned off the gas supply. If you have accidentally switched off your hot water heater’s thermostat, re-light the pilot light (it’s simple — I may write an article on it in the future), and then turn the thermostat back on. For electric water heaters, locate the breaker switch on your electrical panel that supplies electricity to your hot water heater and turn it off. Allow around 20 minutes for the water to warm up. Start by turning on one of your house’s hot water spigots to confirm that hot water is flowing out
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.

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. This is what the sediment in your water heater looks like in terms of appearance.
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
- Open a hot water faucet on an upper floor, as well as the water heater drain valve, if applicable. Keep allowing the tank to empty until silt jams the valve and decreases the flow rate. Closing the hot water faucet and the water heater drain valve on the second floor will conserve energy. Remove the temperature-pressure release valve and replace it with the vacuum adapter
- Then repeat the procedure. Then, connect the shop vacuum hose to the vacuum and start it.

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.
- Tips: If it breaks off in pieces, saw the fractured area with a hacksaw blade until you come across metallic threads. After that, chisel away at the parts using a hammer and screwdriver.
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
- Remove the handle from the ball valve so that you can assemble all of the 3/4-inch fittings
- Create a new drain valve using 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 MIP x G.H. garden hose adapter (one option is the BrassCraft/Plumbshop No. HU22-12-12TP)
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
- Following a thorough flushing of the water heater, remove the ball valve handle, particularly if the water heater is in a location where people may stroll by and accidently bump the handle. Upon opening, hot water may be released, resulting in severe burns. In order to prevent it from falling out of your hand, twist knot it to the valve. Step 6: Organize your thoughts and feelings about your situation.
- 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 Sediment in Step 7.
Step 8: Refill the Water Heater with water.
- Fill the water heater with fresh water
- Turn on the gas or electric

Many homeowners, however, are unaware that cleaning a water heater once a year can help to eliminate a buildup of sediment from the bottom of the tank.
Sediment can form a barrier between the heating components of a water heater and the water, making it more difficult to heat your home’s showers, dishwasher, and laundry.
More information on why you should flush sediment out of your tank may be found here.
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
Keep scalding hot water from being drained. Allow for cooling once the heating components have been turned off. Some bigger water heater tanks might take up to two hours to heat up.
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.

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.

A common occurrence is that the water heater serves as a filter for the hot water lines in your home, which is something that it was not intended to accomplish.
- 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 drives the water to the bottom.
- Although the dip tube drives any sediment in the cold water to the bottom of the tank, it also helps to remove any contaminants from the hot water.
- If you have a gas water heater and you have sediment at the bottom of the tank, the sediment can actually function as an insulator between you and your water.
- 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 burn out.
- Nonetheless, it’s crucial to remember that if you have an older gas water heater and you’ve never done so before, it might not be the greatest idea to do so.
Flushing out the tank could eliminate silt that is sealing a leak, which could cause much worse difficulties down the road. When in doubt about whether or not to do a water heater flush, it is best to get advice from a qualified plumbing technician in your area.

Cleaning your water heater on an annual basis is the most effective approach to ensure that it is as safe and trustworthy as possible. Learn how to flush a water heater by following these steps: In related news, here’s how to clean a TANKLESS water heater.
Drain the Water Heater
Connect a garden hose to the hose bib located near the bottom of the water heater and run the hose to a floor drain or an exterior place to collect any excess water from the water heater. Note: If you have a drainpanunderneath that has been properly connected to a drain, you will not need to use a hose. Turn off the water heater’s electricity, or turn the gas control valve to the “Vacation” position, whichever is appropriate. Close the cold water entry valve, which is normally found at the top of the tank.
Open the drain valve and turn on the hot water faucet nearest to the tank to allow air to circulate through the tank.
It is true that larger hot water heater sizes will take a little longer to drain, but it should not take more than a few minutes in most cases.
The moment has come to upgrade your water heater’s drain valve from the less robust plastic version with the more durable brass version.
Cleaning and Flushing the Tank
If you go to your local hardware shop, you can get a long, thin brush (like this one) that is intended for cleaning refrigerator coils but is also wonderful for cleaning water heater tanks. Insert the brush into the opening left by the drain valve once it has been disassembled. Scrape the bottom of the tank and as much of the inside walls of the tank as you can with the brush, being careful not to scratch the surface of the tank. In the event that your tank has not been cleaned in a while, this process may take some time.
- A short 3/4 inch plumbing nipple should be screwed into the drain hole.
- Make sure a bucket is placed right below the plumbing nipple, or that you have a garden hose connected to the opposite end of the nipple (or let it drain into a properly installed drain pan).
- Connect a hose to the cold water input valve and turn it on for a few minutes until the water flowing out of the hose is clear.
- Some material, such as rust or calcium deposits, may be present in the bucket.
Although it is beneficial, you should still physically flush and clean a water heater, but you will not have to do it on a regular basis. As a result, rather than cleaning once a year, it is recommended that you do it every three years or such.
Completing the Project
Turn off the hot water faucet if it is still running. Rather than replacing the drain valve, you may install an inline ball valve at the end of the nipple to make future cleaning easier and more convenient. It will be necessary to install a second, short nipple to the valve’s outflow side. Wrap plumber’s tape over the threads on both sides of the nipple and tighten the nipple into the tank until it is completely secure. Screw the ball valve into place and tighten it down completely. Open the cold water inlet valve by turning it to the on position.
As soon as all of the air has been withdrawn from the tank, reconnect the electricity or turn on the gas control valve to the “On” position again.

In contrast, the final step – cleansing the tank — is something you may want to do on a regular basis, perhaps every few months, depending on the mineral level of your local water supply. You may save a significant amount of money by learning how to clean your water heater on your own.
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
You must first determine how to switch off your gas water heater before you can begin draining the tank. The environment of a vacation might be ideal. If the pilot light is manually operated, you should also figure out how to do so. Because pilot lighting processes differ from model to model, the original owner’s handbook is the most reliable source of information. If you don’t have a manual, 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 information.
- 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.
In some regions, you may even be able to obtain free power every weekend!
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.
Make sure you know where your main water shut off valve is located and that it is in functioning condition before completing the maintenance listed below to avoid extra damage from water damage in the event that something goes wrong.
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
Preserve a record of the date you conducted or had this service completed so that you may keep a record for yourself and potentially your insurance company in the event something goes wrong. This will help you remember when you completed the task last year, and if you experience any problems with your water heater before the year is up, there may be more serious issues with your water lines or water heater that should be addressed by a professional before it becomes an expensive repair with water damage.
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.

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
This is accomplished by tricking your system into believing it is required to be running, which requires you to open a hot water tap in your home. Despite the fact that water will flow out, it will not be heated at the time of the process. In addition, this procedure is critical because it prevents a vacuum from accumulating in the pipes, which might result in the formation of undesired air bubbles in your water system.
Turn Off the Cold Water Valve
Your water heater will have a supply valve that will connect to the unit and be used to feed cold water to the unit. You will want to turn off this valve while you are completing the flush. It should be positioned on or near your unit, and it will usually be towards the top of the unit’s interior. It will have the appearance of a typical faucet valve, with the possibility of being dyed blue to indicate cold water. It is important to turn this valve off during the flush process to avoid water running into the unit, which would make the whole procedure a lot messier.
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.
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 is the point at which you will most likely want to consult with a professional to evaluate the tank for more significant problems and accumulation. 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 flushing has been completed, it is time to clean up. The first step is to cut off the drain to which the hose was attached in order to prevent any water from escaping through it. Also, remember to turn off the hot water tap in your house that you opened at the beginning of this process as well. Replace the cold water supply valve and let the tank to re-fill with cold water. When your tank is full, you’ll want to open the pressure valve on the tank to allow the air to leave for the machine to function properly.
Finally, re-start the gas and water lines heading to the storage tank.
