How To Drain A Water Heater

Use These Tips to Drain a Water Heater Properly

Most water heater maintenance instructions recommend that you drain a water heater every six to twelve months, depending on how much use it gets. The reason for this is that it will aid in the removal of any sediment or buildup that may have accumulated on the bottom of the water heater tank as a result of the presence of minerals and other particles in the water. As a result of the accumulation, the water heater will have to work harder to heat the water, consuming more energy and increasing its operating costs.

Before You Begin

Before you begin, make sure you understand where the main water shutdown valve is situated in your home. While you won’t necessarily need it during this procedure, it’s always a good idea to be familiar with this valve whenever you’re dealing with any type of plumbing fixtures in your house in case something goes wrong and you need to shut off all water coming through your pipes.

Safety Considerations

When doing this procedure, you will be working with water that can be quite hot. It is possible that you will need to switch off your hot water heater many hours before you begin in order to allow the water in the tank to calm down before you begin. If you are unable to do so, use heavy-duty rubber work gloves to protect your hands from any splashes and safety glasses to protect your eyes from any hot water droplets that may fall over them.

Materials

  • Drain valve (if necessary)
  • Threaded hose cap (if necessary)
  • Drain valve (if necessary)

Perform a Quick Flush

  • Using a garden hose connected to the drain valve, attempt to clean the water heater tank a little bit while the water pressure is still on before shutting off the water supply. In order to accomplish this, first open the drain valve for a few seconds before closing it again. The pressure will blast away any silt that has become lodged in the valve, allowing the tank to empty more quickly. If a significant amount of sediment is expelled, you may need to repeat the process several times. Make certain that you’ve connected your garden hose to an outdoor place or to a bucket in order to collect the water and sediment that will be emitted from the faucet.

Turn Off the Water Heater

  • Turn off the gas to your water heater, or turn off the electricity if you have an electric water heater. Remove water by shutting off the valve on the cold-water pipe above the water heater or the main water supply valve to the home, whichever is most convenient. Test the hot water faucets around the home by turning them on and checking for water to ensure that the pressure has been released. Water may gush out at first, but if the water has been shut off properly, it should quickly slow to a trickle and eventually stop. Be sure to leave a hot water faucet open in the sink adjacent to your hot water heater to ease pressure in the system

Open the Drain Valve

  • Stop using your water heater by turning off the gas to it or turning off the electricity if it is an electric water heater. Turn off the water by turning off the valve in the cold-water pipe above the water heater or by turning off the main water supply valve to the entire home. Test the hot water faucets in the house by turning them on and checking for water to ensure that the pressure is no longer present. If the water has been correctly switched off, it may first pour out, but it should shortly decrease to a trickle. To relieve pressure in the system, keep a hot water faucet open in the sink closest to your hot water heater.

Flush the Tank With Water

  • Once the tank has been completely drained, you may flush it with a few gallons at a time by turning on the water for a few seconds and then allowing it to drain out again until it is completely empty. As soon as the outflow is free of silt, it will be evident that you have completed the process and may proceed to the following stage.

Refill the Water Heater

  • Close the drain valve and remove the garden hose from the system. Make certain that all but one of your home’s hot water faucets are turned off (the one in the bathtub closest to the water heater is best). You may now re-start the water heater by turning the water back on. After that, keep an eye on the faucet you left open and, as soon as you notice that you are receiving nothing but water out of it, turn it off.

Relight the Water Heater

  • Re-ignite the water heater’s pilot light, or if it’s an electric heater, re-energize the circuit breaker. You should be able to use hot water after an hour or so.

Check the Drain Valve

  1. Check for leaks at the spout of your water heater to see if the drain on the heater has completely closed. If the outlet does not completely close, you can stop the leak by placing a threaded hose cap over the hose thread of the outlet. Alternatively, you can replace the valve entirely.

  • The first step is to cut off the electricity or gas to the water heater. After that, close the cold water supply valve, which will prevent water from flowing into the heater. Glue a garden hose to the drain valve at the bottom of the tank and let it flow on the ground outside
  • Activate the drain valve that is connected to the hose. Pulling up on the pressure release valve on the tank’s top will allow it to be opened. Allowing the water in the tank to drain is recommended. If there is still sediment in the tank after it has been emptied, open the cold water valve for several minutes to flush it out. Close the drain valve as well as the pressure relief valve and let the tank to fill up again. If the heater is powered by gas, relight the pilot and switch it on

Why Drain Your Water Heater Tank?

On average, a tank-style water heater sees a large amount of water pass through its tank over the course of a year. While softened water is used in many houses today, certain minerals and sediment are still carried into the water heater — and if you have hard water, your water heater is more adversely affected by higher concentrations of these pollutants. During the storage of water in the tank, silt and minerals fall to the bottom of the tank where they gather. Water passing through them leads them to accumulate over the course of a year, causing troubles for your tank.

  • Corrosion of the tank, resulting in both large and tiny leaks
  • A reduction in the amount of hot water available
  • Popping sounds caused by air trapped in the sediment
  • It’s difficult to get water to boil
  • Utility bills that are higher

When Not to Drain Your Water Heater Tank

While learning how to drain a water heater isn’t a common home maintenance activity, there are specific situations in which you may not want to do so. The first situation is simply if you are not confident in your ability to carry out this maintenance operation on your own. Leaving water heater repair to a professional is always a wise decision in this circumstance since you don’t want to chance causing any damage to your water heater or causing any water damage to your property. Next, if you’ve never done it before, refrain from draining your water heater!

When sediment accumulates in the water heater tank, hot spots along the bottom metal are frequently created, causing the metal to corrode and eventually fail completely.

If your tank is full of sediment, it’s possible that the sediment has actually closed these little leaks over the course of several years. If you drain the water heater and remove the sediment all at once, you will almost certainly end up with a leaking water heater.

What Would Bob Do? Draining a Water Heater

Image courtesy of shutterstock.com I’ve just finished draining my water heater for the first time since it was installed in 1989.24 years ago today! I stopped after approximately five minutes since the water came out incredibly clear and there was no trace of any silt. Is this a sign that my heater is devoid of any sediment? Whatever sort of storage tank water heater you have, draining your water heater at least once a year is a good practice. Over time, sediment accumulates within the appliance, reducing its energy efficiency and causing blockages in other fixtures throughout the house, including the kitchen sink.

To remove sediment from a water heater, it is necessary to drain it not just for five minutes, but for as long as it takes for the water heater to entirely empty.

STEP 1: Check the pressure-relief valve.

Before you empty a water heater, make sure it has a pressure-relief valve, which is the device that prevents the tank from exploding due to excessive pressure. You must confirm that the valve is operating correctly in order to do so. Turn off the water heater’s electricity supply. (If the unit is powered by electricity, simply shut it down.) If it is a gas-powered heater, turn it to “pilot” mode to conserve energy.) After that, open the cold water supply line valve by pulling the lever on the valve.

Once you’ve opened the valve, listen for air and look for water to confirm that it’s working.

In addition, if you open the pressure-release valve and nothing happens—no hissing air, no pouring water—it is likely that the valve has to be replaced. Image courtesy of instructables.com

STEP 2: Run your drain line.

Connect a garden hose to the water heater drain and run it to the outside of your house. You’ll most likely need at least two pieces of pipe if the tank is below grade (for example, in the basement). One will go from the tank to a portable pump, and the other will run from the pump to an outside collection container. In most cases, if your water heater is not in the basement, gravity should be able to handle the job. Allow enough time for the water in the heater to cool down (a few hours at the very least) before opening the drain valve to be on the safe side.

STEP 3: Flush your tank.

After you’ve opened all of the hot water taps in your home, you’ll want to open the water heater drain valve as well. In the event that you have opted to utilize a pump, this is the moment to turn it on. Allow the tank to completely empty before turning on the water supply (short bursts of water may help to dislodge any sediment buildup). Make sure there isn’t any silt blocking or slowing down your drain valve’s flow by doing the following: Remove the drain valve, in other words, to allow the sediment to leave through a bigger hole.

Keep a number of big buckets on standby to catch any excess water.

STEP 4: Finish up.

Re-start the water supply after the water flowing out of your tank looks to be running clean once more. Next, close the water heater’s drain valve and switch on the cold water supply to the house. It’s also important to remember to restore the pressure-relief valve to its original position. Close all of the hot water taps in your home (which you had previously switched on in Step 3) and, lastly, reconnect the electricity to your water heater, which should now be clear of sediment after you completed Step 3.

How to Drain a Water Heater

Is it necessary to empty your water heater? Yes. To avoid scaling and silt from collecting inside the tank, you should perform this procedure once a year, or even more frequently if you have hard water. Sediment might have the appearance of sand, yet it is composed of minerals derived from your home’s water supply. As a result, these minerals do not dissolve and instead condense into little particles within your unit. Unfortunately, if left unchecked, this build-up may create substantial concerns, including time and money savings by decreasing the unit’s efficiency and functioning, as well as the possibility of the water heater failing prematurely, leading you to lose time and money.

How to Flush a Water Heater:

  1. To begin working on your water heater, make sure that all of the electricity to the device has been turned off, including the circuit breaker. Immediately turn off the cold water supply and wait a couple of hours for the heater to cool (this may take many hours). Locate the drain valve on your water heater, which is usually located at the bottom of the tank. It is possible to drain the water from the tank without using the floor drain by using a conventional garden hose and connecting it to the valve. The water will be directed into a bucket. Although many people may simply use gravity to drain water from the device into a bucket, following the manufacturer’s connection instructions is recommended if you wish to pump the water outdoors (which makes disposing the unwanted water easier). In order to avoid damage to your pipes, open one or two hot water taps around the home. Drain the water and look for silt by opening the drain valve. if the water is turbid or cloudy, refill the heater with fresh water and drain it once again Turn the water shut off valve on and off a couple of times to mix up any sediment that has accumulated at the bottom of the tank
  2. Continue to fill and empty the heater as often as required until the water flows clean. If the unit is in good condition, one flushing is usually sufficient, and you will not need to flush it again for at least one year. It may be necessary to consult with a specialist if there is an excessive quantity of sediment in your water. Once the water flows clear and the unit is completely empty, remove the hose and pump from the unit. Close the drain valve and replenish the tank before turning on the water heater’s power source. Turn on the water heater’s power source. Performance should return to normal, with the exception of a few air pockets that will be expelled via the faucets at the beginning. In most cases, the air will be expelled within a few seconds, and then full water flow will be restored to the system. Close all of the water faucets that you have previously opened.

How to Tell if Your Water Heater Has Sediment Build-Up

There are a number of symptoms that your water heater has a sediment build-up, including the following ones:

  • If your water heater has a sediment build-up, there are several signs to look for, including:

2. Wait Before Continuing

It is highly suggested that you allow all of the water in the tank to cool completely before proceeding. Many individuals underestimate the length of time it might take to do this task. It is reasonable to anticipate that the water will take anything from a few of minutes to many hours to chill down. Depending on the size of the water heater, you may need more or less time to complete the project. During this step, you should have your water inlet valve turned to the “on” position. It is critical to wait for the process to complete before flushing the water pipes since you face the danger of burning yourself or destroying goods near where the water will be released.

3. Flush the Pipes

It is highly suggested that you allow all of the water in the tank to cool completely before proceeding.

4. Transfer to an Outdoor Drain

You will be required to discharge your water heater into a drain outside of your property in the majority of cases. Finding a lengthy garden hose is one of the most effective methods of accomplishing this. Additionally, if you have a drain in your basement, you can simply connect the hose to it and transport the water that way. If you need to turn on the water, you should make sure that the hose is long enough. You may store the hose in a garden area if necessary.

If you notice that the water is not correctly flowing out of the faucet, it is possible that the hose has a kink or clog in it. Make sure to thoroughly inspect the hose and avoid any kinks; if you have a blockage, you will need to remove it and replace it.

5. Connect to the Pump

It is necessary to connect your garden hose to the pump now that your water heater has been properly prepared. You’ll need to know if your water heater is above ground or below ground in order to properly install it. If your water heater is located above ground, the job will be a little easier for you. All that is required is the connection of the hose to the tank. After that, you’ll have to let gravity take its course and drive the water downhill and out of the reservoir. Those who have an underground water heater will need to purchase a small pump from the store in order to connect it to the hose.

It’s possible that you’ll need to connect your pump in to for it to function.

6. Collect Water

When emptying your water heater, you should have a bucket nearby to catch the water that accumulates during the operation. Draining your water heater will need you to collect this water in a bucket, which you will need for the following step. Many people also advocate putting your hose in a garden area so that you can really use the water instead of squandering it as much as possible. It is possible to waste a significant amount of water by leaving the hose running to clean out. It is recommended that you collect any extra water using a bucket in order to store and reuse it.

The amount of silt in the water may be determined by collecting it and testing it later.

7. Evaluate and Decide

The amount of silt in the water may be determined by collecting it and testing it afterwards.

8. Flush the Water Heater

For this procedure, you will need to detach the garden hose from which you previously connected the water heater. After that, you must turn off the water faucet as well as the pressure relief valves. After that, refill the tank with water and empty it once more. It is possible that you may need to repeat this process multiple times before the silt is completely drained. As sediment accumulates, the more times you will need to rinse, and the more time it takes. The practice of flushing the sediment-water down the toilet is widely accepted as an effective method of getting rid of the liquid.

If you opt to flush the water down the toilet, make sure to completely clean it. As you drain the tank, make sure to momentarily switch on the cold water valve to ensure that the water doesn’t overflow. This will allow cold water to flow into the tank, allowing it to be refilled and drained again.

9. Put It Back Together

It’s time to put everything back together now that you’ve cleaned out the sediment from the water heater tank. To begin, disconnect the garden hose and switch the pressure release valve to the off position. You’ll also need to re-energize your gas and electrical lines by switching the switches on the side of the tank. Once you’ve completed all of these instructions, your water heater should operate as usual again. The water should begin to fill to its normal level and then stop. After that, you should return to the sink where you had previously released the water pressure in the pipes and turn on the hot side of the faucet.

Additionally, it should be refilled with water.

Continue to run it until a continuous stream of water is produced.

If you are still experiencing problems with the tank, you may need to seek expert assistance.

10. Monitor and Keep up on Maintenance

Know When to Drain the Tank

Natural minerals found in your home’s water supply might accumulate at the bottom of your water heater tank over time, causing it to malfunction. Because that sediment can impair the effectiveness of the heater, limit its life, and even cause blockages, keeping it cleansed is a good idea. Experts recommend that you wipe away the sediment around once a year, according to the experts. Part of determining when to do it will depend on how hard your water is and whether or not you’re linked to a municipal water supply where sand and grit may find their way into the water supply.

The practice of draining once a year is reasonable, and if you discover that there isn’t too much silt present when you perform the task, you may be able to reduce the frequency of maintenance to once every other year, or perhaps every three years.

How to Drain a Water Heater

The first step in this project is to make sure that your water heater is turned off before you begin. With a gas water heater, you may accomplish this by setting the knob to “pilot.” The circuit breaker that controls your electric heater must be found and turned off in order to prevent damage to the heater from occurring. Typically, the water heater is protected by a separate circuit breaker. It will be necessary to turn off the cold water that feeds into the tank as well, which can be accomplished by twisting a knob located at the top of the tank in the opposite direction.

Step 2: Run the Drain Line to a Good Draining Location

In order for the water within the tank to be able to depart, you must first provide a passage for it. As long as your water heater is elevated or located on a higher floor of your home, the process of draining the water heater can be as simple as connecting the heater to a safe draining position outside your home. If the water heater is located below grade, such as in a basement, you have two options to consider. Use a bucket to collect the water, or you may purchase a pump and attach a hose line to pump the water up and out of the hole.

Step 3: Check Your Pressure Relief Valve

When it is not a “must-do” step in the process, inspecting your pressure relief valve while cleansing your water heater is always a good idea regardless of whether it is necessary. It will aid in the release of pressure in the tank, preventing the formation of a vacuum. You just switch the latch on a valve located on the cold water pipe that supplies the tank in order to do this task. The valve is in excellent operating condition when you hear a hiss and see water spurting out – it’s a good idea to do this with a bucket or cloth nearby, by the way — which indicates that the valve is in good working order.

Step 4: Open the Hot Water Faucets in Your Home

Start all of your hot water taps in your house at the same time to alleviate even more pressure in the tank and aid in its emptying. If you want, you may just turn on the hot water tap that is nearest to the tank. Additional Related Articles:

  • Whether a tankless water heater is worth the investment.

Step 5: Open Your Drain Valve

Prepare your bucket or pump system, and then release the drain valve located towards the bottom of the tank to allow the water to drain. A built-in knob is normally available for this valve, however it is occasionally necessary to put a flat-head screwdriver into a slot and turn it counterclockwise to operate it properly. It is at this moment that water will begin to pour out of the tank in large quantities, so be prepared to collect or redirect it as soon as possible. In order to empty your bucket, you can shut off the valve whatever many times you need.

Step 6: Flush the Tank

However, even though much of the sediment will be removed simply by draining the tank, it’s always a good idea to check that your water heater is completely clear of sediment by flushing it with cold water. To do so, just turn the cold water knob at the top of the tank back on and let it run until the water drains completely out of the hose linked to the drain valve, which should take around 15 minutes. If the water flow stops at any time throughout the draining process, you’ll want to remove the hose and use a tiny screwdriver or awl to scrape away any debris that may have accumulated in the output.

You should switch off the cold water faucet and seek expert assistance if you are unable to see or clear the sediment.

Step 7: Refill the Tank and Turn It Back On

Remove the drain knob from the water heater once it has been completely cleansed and the output is flowing freely again. Ensure that you close your pressure release valve if you had previously opened it. Then, reconnect the cold water supply line at the top of the tank by turning it back on. Make your way to the hot water spigots that you previously unlocked and wait for the water to start flowing through them. When this occurs, you will be able to turn them off. Depending on the type of water heater you have, you will need to either turn the electricity back on or the gas back on.

How to Flush Your Water Heater

Remove the drain knob from the water heater once it has been completely cleansed and the output is running cleanly. If you opened your pressure release valve previously, be careful to close it. Then, reconnect the cold water supply line at the top of the tank by turning it on again. Make your way to the hot water spigots that you previously unlocked and wait for the water to begin flowing through them. You will be able to turn them off after this is accomplished. In order to restart your water heater, either the electric or gas should be turned on again.

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.

  1. 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.
  2. The main water valve to the house in some residences; in others, a shutdown valve near the water heater may be used instead.
  3. Connect a garden hose to the tank’s drain spigot, which is located towards the bottom of the tank.
  4. 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.
  5. 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.
  6. 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.

How to Flush or Drain a Water Heater

Remove mineral sediment and scale from your water heater tank twice a year by flushing it out. Your water heater will heat more effectively and last longer as a result of this improvement. This professional advise demonstrates how to flush and drain a water heater through the use of videos, pictures, and easy-to-understand language. What is the significance of flushing or partially draining a water heater? For the simple reason that it reduces the accumulation of mineral deposits within the water heater.

  1. A very thick, crusty layer can grow at the base of a gas water heater, and the heating components of an electric water heater can be completely covered by these sediments.
  2. It eventually results in rusting as well.
  3. They can also block the valve that is used to flush or drain a water heater tank, causing it to not function properly.
  4. The hypothesis goes like follows: A small crack in the base may have filled with silt, which can assist prevent leaks, especially in a gas water heater where the flame has been roasting the steel bottom.
  5. In the event that your water heater has not been cleaned in several years, it would behoove you to consult with a few of plumbers in your neighborhood for their recommendations.
  6. Flushing or partly draining a water heater at least once a year from the time it was initially installed is the most prudent approach to follow in this situation.
  7. If you decide not to undertake the repair yourself, you could expect to pay a plumber between $80 and $100.
  8. Diagrams of Electric and Natural Gas Water Heaters It is necessary to drain a water heater tank in order to replace or repair it, as well as to remove mineral deposits from the tank, through the drain valve located at the bottom of the water heater.

The drain valve looks like a little outdoor faucet. If you use this valve, keep in mind that the water will be hot until the water has had time to cool before the water is released. In a nutshell, here’s how to flush or empty a water heater on your own:

  1. The water heater’s gas or electricity should be turned off. Close the cold water intake valve and turn it off. Connect a hose to the water heater’s drain valve and route it to the location where the water will be drained
  2. Open a hot water faucet in a convenient location around the house. Open the water heater drain valve (caution: hot water will be released! )
  3. Close the valve after flushing 3 to 4 gallons (if emptying, continue until the tank is empty)

Please continue reading for additional information on these processes.

How to Flush or Drain a Water Heater Tank

Listed below are the procedures to be followed while flushing or emptying a water heater. This video provides a wonderful summary of the subject: To turn off the gas or electrical power to the water heater, depending on whether it is a gas or an electric water heater, follow these steps: The “Pilot” setting on a gas water heater is as simple as turning the gas control to “Pilot.” 2 Turn off the cold water inlet valve, which is responsible for regulating the supply of water into the tank.

  • Make certain that this is the incoming cold water valve and not a valve for the outgoing hot water supply (the pipe should be cold).
  • The supply to this water heater is controlled by a lever valve.
  • 3 Using a hose, connect it to the tank drain valve, which is located in the bottom of the water heater, and direct it to a drain, the outdoors, or a large bucket.
  • Fill the tank with water by connecting a hose to the water heater’s drain valve.
  • As the water drains, this prevents a vacuum from building in the system.
  • To avoid scorching, exercise extreme caution.
  • 5Depress the drain valve on the water heater.

Once this is done, close both the drain valve and the PT valve.

In the event that you are totally draining the water heater, leave the drain valve open until the tank is completely empty.

7Refill the water heater with fresh water.

Return the water supply valve to its original position to re-fill the tank.

Then, reopen the hot water faucet to allow any remaining air to escape from the tank and pipes.

Allow the water to clear for a few minutes before turning off the faucet. 8Restart the water heater if necessary. If you have a gas water heater, relight the pilot light, or switch on the electric circuit if you have an electric water heater.

Water Heater Won’t Drain

If your water heater is draining slowly or not at all when you open the drain valve, you should try opening the pressure-relief valve to see if it helps (see the illustration at the top of this page). This has the potential to dislodge the vacuum that is keeping the water from leaving. In most cases, if the water heater won’t drain or drains slowly, the problem is most likely due to an excessive amount of sediment building up in the water heater. The drain valve of a water heater can become clogged with sediment.

First Steps in Breaking a Drain Valve Clog

1Detach the water heater from the mains. Depending on whether the water heater is gas or electric, switch off the gas valve or the circuit breaker that supplies electricity to the water heater. Secondly, connect an outside hose to the drain valve and run it outside, making sure that the hose’s end is below the level of the water heater. Turn on a hot water faucet someplace in the home or open the pressure-relief valve on the water heater to dislodge the vacuum that has built up inside the tank.

If the water flows freely, the valve is functional.

4 In the event you believe that the drain valve has become clogged, you can attempt to shoot water and air bubbles back into the tank by repeatedly walking on the hose a few feet away from the tank.

If it does not, continue reading.

How to Back-Flush a Water Heater

A hose is connected between the drain valve and an outdoor faucet, and water is squirted back into the water heater through the drain valve in order to backflush it. For this project, you’ll need two male threads connected together with a double-female garden hose coupler (which can be purchased online for approximately $8).

How to Flush a Water Heater Video

Take a look at this video, which demonstrates the procedure of cleansing your hot water heater.

Back-Flushing a Water Heater Step-by-Step

1First, perform the steps outlined above for preparation. 2Close the drain valve on the water heater by twisting it in the clockwise direction. 3Connect the male end of the garden hose to an outdoor hose faucet or a washtub faucet by means of the female hose coupler that was previously installed. Hose Coupler with a Double Female EndBosch4 Turn on the faucet to fill the hose with water pressure and fill the hose with water. 5Depress the drain valve on the water heater. A torrent of water should be forced into the water heater, forcing deposits away from the water heater’s valve.

7Remove the hose from the water faucet and attempt cleansing the tank once again with the hose. If the water heater’s drain valve is still not functioning properly, the next step is to either replace the drain valve or to replace the water heater.

How to Replace a Water Heater Drain Valve

As previously noted, flushing a water heater is a vital element of doing basic DIY water heater maintenance. Unfortunately, the drain valve on a water heater can get blocked with mineral deposits to the point where it must be completely replaced. Step-by-step instructions on how to replace it may be found here. Valve for the drain of a water heaterB K Water heater drain valves are available for purchase at most hardware stores and on the internet for around $8 per valve, depending on the model.

Water heaters have a drain valve that is positioned at the bottom of the tank.

Having a helper use buckets to collect and dump water that is flowing from the water heater while you remove and replace the valve will be the norm in most circumstances, but it may be necessary in other cases.

Expect to be drenched as a result.

This will take some time.

To do this, switch off the cold-water supply to the water heater and ensure sure no one comes into contact with any of the hot water fixtures or appliances in the house while the valve is being changed.

After that, turn off the circuit breaker on an electric water heater or the gas valve on a gas water heater to prevent the water from reheating further.

Allow for the water in the water heater to drop down to a safe temperature before using it once more.

Before you begin the task, make sure you have two buckets, a pipe wrench, a screwdriver, and the new valve on hand to make the job easier.

Wear leather-palm gloves and have a helper as well as lots of rags on hand before you begin.

The water will begin to seep as the seal loosens, then spray, and ultimately pour warm (or hot) water!

Remove the valve completely from the system.

Insert a screwdriver into the hole and move it around to break up any deposits that have accumulated.

4.

5.

Disconnect the tank’s water supply with a hose until the water begins to flow clean of sediments.

In addition, if you’ve opened the water heater’s pressure-release valve or any hot water taps, make sure you close those as well.

8 In order to restart an electric water heater, turn the circuit breaker back on, or open the gas valve and ignite the pilot (or use the electronic ignition) in order to restart a gas water heater, following the manufacturer’s instructions.
