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.
- 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
- 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

In order to enhance energy efficiency and increase the lifespan of the unit, water heaters, like most appliances, require routine maintenance to ensure that they operate at peak performance.
An yearly water heater servicing performed by a certified plumber is the most effective approach to safeguard your investment.
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.
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?
Step 1: Turn off the cold water supply to your water heater. Step 2: Turn on the hot water supply. Water shutoffs may be required where the main water supply line enters your home, which is common in older properties. 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 soften as much. Second, switch off or lower the thermostat on the water heater. It may be possible to turn off your water heater’s heating element while on vacation.
- Additionally, before continuing, you should turn off the natural gas supply valve.
- The hose’s other end should be connected to a drain or a safe location outdoors.
- You should also direct the water away from shrubbery or other plantings if you are directing it outside.
- A speedier draining process will be achieved by doing so.
- As long as you maintain your finger on the vacuum, the liquid will remain trapped within.
- Keep an eye on the water as it rushes out of the hose to see how much silt is being carried away.
- If you open the drain valve and no water comes out, it’s likely that sediment has clogged the valve.
Using a wet/dry vacuum, remove part of the obstruction from the drain valve—at the very least enough to restore water flow.
Before replacing the drain valve, remove the temperature pressure release valve and use the wet/dry vac to remove any remaining water from the system.
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 procedure.
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.
Disconnect the hose from the drain valve and use a wet/dry vacuum to remove any silt that has accumulated around the valve.
A little won’t hurt, but you want to make sure there’s enough space around the valve to prevent it from dripping.
Keeping the hot water taps open until the water starts to flow is the eighth step.
If you notice rust or sediment pouring out of the drain at first, don’t be alarmed!
Step 9: Adjust the temperature of the water heater to your preference.
To do so, reopen your gas supply valve and follow the manufacturer’s instructions for doing so.
The time it takes to fill the tank should be between 15 and 20 minutes, while the precise time depends on the size of your water heater, its general efficiency and whether it’s powered by natural gas or electricity;

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
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. You’ll want to wait around 30 minutes before checking for hot water. Turn the cold water valve back on and the heating elements back to the on position. Make sure that your taps are still running and that they have returned to a regular flow. The water heater should have reheated the liters of water contained within the tank once more, this time without sediment!

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
The silt and accumulation that naturally occurs in water heaters accumulates over time as a result of their frequent use. Sediment can accumulate in the heater and clump together, resulting in decreased performance or damage to the device, depending on the situation. When it comes to water heaters in Phoenix, where the water is extremely sediment-rich, this is a particularly typical problem. In addition to preventing excessive sediment building, flushing out your heater will guarantee that you are able to use the unit more efficiently and with less concern about failure.
How Frequently Should You Do a Hot Water Heater Flush?
If you consider how important your water heater is, you should not put off cleansing your system for an extended period of time. Every water heater has a varied lifespan, but making sure you clean out your water heater on a regular basis can help it last as long as it was designed to. A flushing of your heater should be done every couple years or so, on average. In order to guarantee the optimum performance from your unit, flushing it once a year is recommended, and the following instructions will demonstrate how simple it is to do.
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.
As you work on the equipment, this will help to avoid any electrical problems from developing. 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 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.
This will signal that the system has been completely cleansed and that the procedure is nearly completed. 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.
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.
Flushing a Water Heater: Why Should I Flush My Water Heater?
Regular maintenance is required for your water heater, just as it is for other devices such as your automobile. Water heaters accumulate sediment, calcium, and minerals over time, which settles to the bottom of the tank and causes it to get clogged. It is at the bottom of the tank where the water heater’s heating element is located. The water heater will have to work harder to heat the water if the heat is being blocked by silt and other foreign objects. There aren’t any negative consequences to flushing a water heater.
How Often Should I get My Water Heater Flushed?
It is advised that you clean your water heater at least once a year to keep it running efficiently.
This will aid in the prevention of the possible difficulties that silt might cause over time if left unchecked.
What Happens if I don’t Flush My Water Heater?
It is possible that leaving sediment buildup in your water heater would not only make it work harder, but it may also result in some major complications. For example, if the sediment builds up to a significant level, you may see it coming out of your faucets and drains. Sediment, on the other hand, can produce much more significant problems over time. Things like a ruptured pipe, a lack of water pressure, or even the failure of the tank itself are all possibilities. These issues often manifest themselves over a period of two to five years.
Do I Need to Flush a Tankless Water Heater?
Yes. Tankless water heaters, despite the fact that they do not store as much water as traditional tanks, can nevertheless accumulate sediment, necessitating regular cleaning and maintenance.
How do I Flush My Water Heater?
- Shut down the gas or electricity if you have a gas water heater, or the electricity if you have an electric water heater. Allow the water heater to cool for a short period of time
- Turn off the water supply. Start by turning on the hot water from a nearby faucet to avoid a vacuum from building and to make it easier for the tank to drain
- To drain the water, connect an empty bucket or drain hose to the valve and run the hose down to the drain. During this procedure, you may need to empty a bucket numerous times. Drain the water heater tank by opening the drain valve and allowing the water to run until the tank is completely drained. If you haven’t allowed the water heater to cool down properly, the water can get quite hot at this point
- Proceed with caution. Remove any remaining sediment by restoring the cold water supply and allowing it to drain. Carry on like this for a couple of times to get rid of all the silt
- Drain the water by closing the drain valve. Reopening the water supply valve will allow you to refill the water heater tank. Start the water heater by turning it on.
In the home, removing the water heater’s tank is possible, but it might be hazardous. If you are unsure about flushing your water heater yourself or want to ensure that it is done correctly, call a professional expert to have your water heater cleansed in no time at all.
How To Flush Your Water Heater The Right Way
In the house, removing water from a water heater is possible, but it can be hazardous. If you are unsure about flushing your water heater yourself or want to ensure that it is done correctly, contact a professional expert to have your water heater cleansed in no time at all.
First Things First
It is necessary to begin by cutting off the water supply to your tank’s holding tank. Simply cut off the water pipe that supplies the water to the tank and the problem will be solved. This will prevent any extra water from filling the tank and will also enable the present water to cool down a little bit. To shut off your heater, you will either need to cut off the gas supply or turn off the breaker on your electrical panel, depending on which type of heater you have. By turning off the heating element, you can avoid any potential fire threats in the future.
Connect Up To The Drain Valve
After that, you’ll need to connect a garden hose to the drain valve located at the bottom of the hot water heater. Be advised that certain models may have a protective cover over the drain valve that you will need to remove before you can use the drain valve. Run the hose directly into a drain, a large bucket, or even onto your driveway so that it may securely drain away from your home.
Drain Your Water Heater
Step three involves opening the drain valve and allowing the water to drain. Because the water will be quite hot, take care not to burn yourself. It is possible that you may notice that the water begins to drain more slowly near the finish. An indication that silt has accumulated in the tank and needs to be flushed from the system is this symptom. This may be accomplished by turning on the cold-water input that serves as a conduit to your hot-water tank. The influx of cold water will dislodge any sediment in the water heater and allow it to drain out of the system.
If the water in the tank is clear and not brownish in color, you should be satisfied with the results.
You should always consult with a professional plumbing and electric company before flushing and maintaining your water heater. Water heater maintenance is essential if you want to extend the life of your heating appliance.
Finishing Things Up
As soon as the water heater has been rinsed out, turn off the drain valve and then disconnect the drain line from the water heater. Keep in mind to turn off the pressure release valve. After that, you may switch on the cold-water input and wait for the tank to fill completely. When the tank is completely full, it is necessary to open the pressure relief valve in order to remove any remaining air from the tank. If you have a gas heater, you’ll need to re-ignite the pilot light and reconnect the gas line to the heater.
It is also critical to carefully adjust the thermostat in order to maintain the ideal temperature for your water heater.

How to Flush a TANKLESS Water Heater (Part 2)
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.

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 couple additional faucets (on the hot side) in the home 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 pipes 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 appropriate temperature setting once more.
