How To Drain My Hot 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.

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 into a bucket in order to collect the water and sediment that will be emitted from the faucet. The Spruce / Kevin Norris

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 flood out at first, but if the water has been cut off properly, it should rapidly decrease to a trickle and then stop. It is important to leave a hot water faucet open in the sink closest to your hot water heater in order to relieve pressure in the entire system. The Spruce / Kevin Norris

Open the Drain Valve

  • Open the drain valve while holding your garden hose in one hand. Normally, you may complete this task by hand, but you may need to employ your flat-head screwdriver in this instance. Once the valve is opened, water will begin to rush out of the drain, so make sure your hose is either connected to the outside or to a bucket to catch the water. You should switch off the drain valve as soon as the bucket is full so that you may empty it. Repeat the operation as many times as necessary to completely empty the tank. The Spruce / Kevin Norris
  • The Spruce / Kevin Norris

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. When the outflow is clean, you’ll know that you’ve successfully eliminated the sediment and may proceed to the following phase in the process. The Spruce / Kevin Norris
  • The Spruce / Kevin Norris

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. The Spruce / Kevin Norris
  • The Spruce / Kevin Norris

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. The Spruce / Kevin Norris
  • The Spruce / Kevin Norris

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.

How to Drain a Hot Water Heater

Previous PostNext PostWhen was the last time you emptied the water from your hot water tank? When it comes to hot water, we all take it for granted, until it is no longer available. A shivering shower serves as a stark reminder of the significance of regular water heater service. Draining a hot water heater is one of the most important preventative maintenance jobs a homeowner can perform to help extend the life of the unit’s performance. It is important to drain your hot water tank because it reduces sediment accumulation, which allows your water heater to operate more effectively, which can result in cost savings.

Draining Your Hot Water Heater

If you want to empty your hot water heater, you’ll need a length of garden hose that’s 3 to 4 feet long and has a connection that can connect to the drain valve at the bottom of the tank. Many times, this is the same sort of fitting that you use on your water supply line. Plan to direct the flow of the hose into either a bucket or a floor drain, depending on which is most convenient for you and your situation. Turn off the gas and extinguish the pilot light if you’re working with a gas water heater to start the repair process.

Occasionally, it is not essential to completely drain the hot water tank.

Homeowners will also be prevented from accidentally harming their hot water heater by turning it on while there is no water. This can also shorten the time it takes to replenish the hot water tank, which might take a long time if the tank is completely depleted.

  1. Deactivate the water supply valve that feeds into the hot water tank. Inspect the water heater’s drain valve, which is located at the bottom of the unit. Open the same valve you used before. Make sure that the pressure release valve is open. Allow the water to drain completely. If you aren’t utilizing a floor drain, make sure you empty the bucket on a regular basis. Turn on the water supply valve when the tank is completely depleted. Ensure that the water continues to flow through the tank and through the drain valve until it is clear. Close the drain valve as well as the pressure release valve to allow the tank to fill. In the case of an electric water heater, reset the circuit breaker or reconnect the device. To relight the pilot light on a gas water heater, turn on the gas and relight the pilot light.

While this may appear to be a straightforward procedure, there is the possibility of flooding in your basement if you do not proceed with caution. Plastic hot water heater valves, as well as valves that have not been used in a long time, are susceptible to leaking. Continue to keep an eye on the valve after it has been shut in order to verify that it is not malfunctioning. Even a little trickle might quickly escalate into a major issue.

What Would Bob Do? Draining a Water Heater

Image courtesy of 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. Draining a water heater should be done in the following stages in the future:

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.

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 (& When You Shouldn’t!)

Homeowners in Birmingham who have classic tank-style water heaters need to know how to empty a water heater properly.

This is a vital step in the maintenance of a water heater. You will receive step-by-step instructions on how to do this work yourself from our plumbing pros, as well as information on when you should call a professional and when you should refrain from draining your tank.

How to Drain a Water Heater Tank

Tank water heaters should be emptied about every six months by performing the following steps:

  1. Make sure that your unit’s electricity or gas is turned off. The cold water supply valve (the valve that delivers chilly water into the tank) should be closed on the unit. Connect a garden hose to the drain valve on the water heater, which is situated towards the bottom of the tank
  2. Drain the water from the garden hose outside or into a bathtub for drainage. The drain valve should be opened once the line has been fastened and sent outside or to a drain Open the pressure release valve, which is located at the top of the machine. Allow enough time for the water heater to drain completely. When your water heater tank is completely depleted, reopen the cold water valve and allow the water to flow for a few minutes to flush out any remaining particles. Close the drain valve and pressure release valve, then disconnect and empty your garden hose
  3. To restart the system, turn on the power or relight the pilot light on your water heater.

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 you drain the water heater and remove the sediment all at once, you will almost certainly end up with a leaking water heater.

Frozen Hose Bib: How to ThawPrevent Major Water Damage

The capacity of hot water tanks is meant to last for many years, but cleaning them should be included in your normal home maintenance program. Following our step-by-step directions outlined below, this is an easy DIY project that you can complete on your own.

Why should I flush my water tank?

The majority of hot water tanks feature a large holding tank, which guarantees that there is always sufficient of hot water available when it is needed. Nonetheless, because the water is left to stay in the tank on a continuous basis for an extended period of time, naturally occurring minerals in the water, as well as sand and grit discharged from municipal water pipes, can accumulate in the tank’s bottom. The accumulation of silt in your hot water tank may make it more difficult for it to perform its function.

This increases the likelihood of your water heater breaking sooner than it should. Hot water tanks should have a life lifetime of at least 10-12 years, however failing to remove the sediment from the tank on a regular basis can dramatically shorten that life term.

What about my gas hot water tank?

In addition, sediment can reduce the effectiveness of the burner in a gas water heater. Have you ever experienced cracking and popping noises when your furnace was heating up? This is due to the silt that has accumulated in your tank. Sediment builds up in a gas hot water tank, forming a thick, crusty layer on the surface. This reduces the amount of heat that is transferred from the burner to the water in the tank. This is a waste of energy and, more importantly, of your money! In the long run, this can create corrosion in the tank, which may produce a major problem if your tank begins to leak all over your floor.

This will guarantee that your water heater performs at its best.

Can sediment affect my plumbing pipes or water?

Fortunately, the quick answer is “yes!” The sediment or crusty stuff that collects at the bottom of your tank has the potential to break loose and become caught in the pipes that distribute water throughout your home. This might cause the flow of water via your pipes and faucets to become more difficult to control. It also has the potential to clog the drain valve on your hot water tank, making it hard to drain the tank without a major plumbing repair job.

An important word of advice:

If you haven’t cleansed your hot water tank in a number of years, it may be in your best interests to hire a Licensed Plumber to take care of the job on your behalf. You run the danger of causing leaks to be activated. It’s conceivable that the silt that has been accumulating in the tank for years has developed fractures in the bottom of the vessel. The existing sediment is clogging those cracks, however draining and flushing the hot water tank may be able to remove the sediment that is “sealing” the leaks and allowing them to reopen.

The fact that you hired a Licensed Plumber to complete the operation ensures that if it does leak, you’ll be prepared to deal with it immediately.

Speaking from experience.

The reason I warn you with the word of advise above is that we had exactly that scenario occur with a client of ours and we wanted to share our experience with you. Approximately 7 years ago, I published a simple advice to draining your hot water tank in a newsletter that I had written. After eight years in his house, my client realized that he had never drained the tank and decided that it would be a good idea to do so now that the weather was getting warmer. He diligently followed all of my directions before calling me in a panic because there was water coming out into his basement floor and he needed me to come immediately.

He, on the other hand, had not anticipated such a problem as a result of following my detailed directions.

It was clear that they had been there for a long time, and the sediment itself was preventing the leak from occurring again.

Our customer ended up needing to purchase a new hot water tank, but he ended up saving a significant amount of money over the long run since his new tank was far more energy efficient. Our client now flushes his hot water tank once every six months as a preventative measure.

One important first step

The first step is to identify where the drain valve is located on your tank. It has the appearance of a little outside faucet. Before draining your hot water tank, we highly advise that you cut off the gas or electricity to the tank and let the water drop to room temperature before draining it. It will take several hours to complete this task. This is not required in order to drain your tank, however it is recommended as a safety measure. If you do not want to wait the appropriate amount of time for all of the water in your water heater to cool, just keep in mind that the water that comes out of the drain valve will be extremely hot when it does.

Steps to Draining Your Hot Water Tank

  1. Turn off the gas or electrical power to your hot water tank if it is connected. The “pilot” setting on a gas water heater is what you’ll want to use. If the water heater is electric, turn off the breaker or unplug the fuse located at the electrical panel
  2. Turn off the cold water supply valve located at the top of the water heater
  3. And turn off the gas supply valve located at the water heater. When you touch this pipe, it should be ice cold. If the valve feels warm to the touch, you’ve got the incorrect valve. Locate the tank drain valve, which should be towards the bottom of the tank, and connect a regular garden hose to the drain valve. Keep in mind that certain models may have a cover over the valve opening
  4. The other end of the hose should be placed in a floor drain or on a driveway where it may safely drain. Buckets can be used if required, but take care not to be burnt by the hot water while you’re doing your task. To prevent this from happening, make sure the hose’s end is lower than the water tank’s valve. Locate the hottest water tap that is closest to the water heater, preferably on the second or third story above. Opening the drain valve and allowing the water to flow from the tank can relieve pressure in the system, similar to withdrawing your finger from the top of a drinking straw loaded with liquid
  5. Close the drain valve and let the water to drain from the tank. Once again, if you haven’t allowed the water to cool before using it, proceed with caution. Once all of the water has been emptied from the tank, switch on the cold water supply to the tank for a limited period of time. This will help to stir up any silt that has accumulated. It is necessary to repeat this procedure until the water flows clean
  6. Disconnect the drain line and switch on the cold water supply valve after closing the drain valve. The tank will begin to fill as soon as possible. Return to the hot water faucet that was previously opened. Once cold water begins to flow from the faucet, cut off the water supply. Return the gas valve to the on position from the pilot position, or reconnect the power to the tank. It is important to double-check the valve opening once it has been closed to ensure there are no water leaks.

What if my tank won’t drain?

If your hot water tank is draining slowly or not at all, open the temperature and pressure relief (TPR) valve on the hot water tank to see if it helps. In the hot water tank, it’s at the top where you’ll find it. A pipe goes from the top of the tank to the bottom of the tank, and it’s normally operated by a lever that may be raised or lowered as needed. Opening the TPR valve may allow water to drain from the tank if there is a possible vacuum inside the tank that has been preventing it from doing so.

The most prudent course of action is to contact a Licensed Plumber in this situation.

To sum things up.

Despite the fact that it is one of the most often used items in your home, the hot water tank is also one of the most ignored. If you follow the methods outlined above, maintaining your hot water tank will be a simple chore. If you prefer that our Licensed Plumbers handle the maintenance on your hot water tank, please contact us at 905-259-3344 to make arrangements.

How Often Should I Drain My Water Heater?

Although water heater manufacturers may offer precise guidelines on how often a water heater should be emptied, the general rule of thumb is that your water heater should be drained once per year. Generally speaking, the goal of emptying your water heater is to remove any hard water or sediment that may have accumulated over the course of its operation. In addition to reducing the lifespan and effectiveness of your home’s water heater, removing deposits from the tank through water heater draining is an excellent preventative maintenance practice that is quite easy to perform.

  1. Remove the re-circulation pump from the system in step 1.
  2. Before proceeding on to the following step, be sure you hear the pump shut off completely.
  3. Step 2: Shut down your water heater and let it cool.
  4. While you are working on the water heater, this will prevent the flame from igniting accidentally.
  5. Shut down the water supply to the water heater in Step 3.
  6. While you are emptying the system, this will prevent any extra water from entering the water heater and causing it to malfunction.
  7. Locate the drain valve at the bottom of your water heater tank and connect a hose to it with a rubber band or zip tie.
See also:  What Is A Heat Trap On A Water Heater

Before you open the drain valve, double-check that the water is draining to a suitable location in your residence.

The valve opener, which should be located on the side of the valve at the bottom of your tank, should be used to open the valve.

Some water heater tanks are equipped with pressure release valves on the exterior, which make it simple to add air into the system as necessary.

In any case, you should be able to hear the water being put into the system, and the water will begin to drain shortly thereafter.

Allow ample time for the tank to drain entirely, especially if you’re using a bucket as advised.

The discoloration of the water may indicate that it is time to update your water heating system.

Whatever technique you chose in Step 6, it is now time to seal the system and prevent air from entering by closing the pressure release valve or tightening the bolts located on top of your tank.

This will allow water to flow into the tank, flushing any more deposits out of the system as it does so.

Keep in mind to verify all connections at least twice and maybe three times.

Immediately after removing your pump in step 1, open all of the hot water faucets and fixtures in your house and allow them to flush for a few minutes before reconnecting your pump.

Finally, switch your gas tank from ‘pilot’ to ‘on,’ or re-plug your electric tank into the wall, whichever is applicable.

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?

Hot water heaters are available in two different configurations: gas and electric. Due to the fact that I have a gas hot water heater, following instructions will be specific to flushing a gas hot water heater. While there are some similarities between gas and electric, the most significant distinction is that with gas, you will be shutting off the gas to your appliance; with electric, you will be turning off the power to your appliance. 1. Turn the Thermostat on your hot water heater to the “Off” position.

  1. In most cases, the thermostat for a gas hot water heater may be found in the bottom of the tank.
  2. If you switch off your hot water heater and it’s an older type, you’ll have to re-light the pilot light, which might be a hassle.
  3. 2.
  4. If you have a gas hot water heater, locate the gas pipe that runs from the tank to your thermostat and pilot light and switch the valve to the “off” setting.
  5. 3.

  7. Turn it all the way off.

Fill a sink or tub with hot water by turning on the faucet.

As a result, you will be less likely to have a vacuum build in the pipes while draining the hot water tank.

Connect the garden hose to the drain spigot on the wall.

Depending on whether or not your hot water heater is located in the basement, you may require a portable pump in order to pump water from the basement to the first floor of your home.

Turn on the spigot and drain the water.

If your tank is clogged with silt, you may need to thoroughly drain it.

I decided to drain it anyhow.

Flush your hot water tankTo flush your hot water tank, just switch on the cold water tap that leads into your hot water tank.

This might take some time.

Here’s a photo of the water that was flowing out of my tank when I first started flushing the toilet: As you can see, there was still some silt (which can be seen at the bottom) pouring out of the hole.

Flushing should continue until there is very little or no sediment left in your water. Turn off the cold water faucet that feeds into your hot water tank and leave it shut.

Finishing Things Up

Following your satisfaction with the purity of your water, it’s time to return everything to their original state.

  • 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.

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).

Your Water Heater-to Drain or Not to Drain? — Norfleet Family Plumbing

A frenzy of activities awaits Mesa’s citizens as they prepare their houses for the long, hot summer that is about to begin. “Do I have to dump my water heater tank every year?” is a topic we are asked rather frequently. In all seriousness, it is dependent. Each hot water tank is unique, based on a variety of circumstances that include not just where the tank is located in the Valley, but also whether or not the tank is equipped with a hydro-jet to decrease silt accumulation. On its route to water consumers, valley water passes through a number of filters and screens along the way.

There will also be a break or that specific location may “flush out” its lines, which implies it will arrive to the customer at some point.

Sediment tells

Until a homeowner drains their hot water tank to check how much sediment has accumulated in the meanwhile, they will have no way of knowing how frequently to do so. In other tanks, it’s practically non-existent. In the same period of time, other tanks can build several inches of silt, which is sufficient to clog the spigot. After it has been emptied for the first time, the amount of material left provides a very accurate indication of how quickly the sediment accumulates. However, if it occurs in an area where there is a break in the water line or when the water line is flushed, a substantial amount of silt might suddenly develop in the tank.

Draining just approximately a gallon of water once a month is recommended by certain water heater manufacturers, while others advocate doing it once a month. Some folks do not drain their water heater tank on a regular basis.

What happens during the drain?

It is possible that silt has accumulated at the bottom of the tank. It might be a small amount or a large amount. The sludge at the bottom of the tank interferes with the tank’s ability to heat the water, causing it to work harder to heat the water.

How to drain a tank

The following is a broad outline of how to go about it. Refer to the hot water heater owner’s handbook for more information:

  • Get yourself a hose. It is preferable to have one with a rubber gasket in it, since this will aid to prevent leakage at the hose connection. The electricity to the water heater should be turned off. This is not optional since if the water heater is not turned off, it might cause it to overheat. Turn off the water that is being fed into the water heating system. Otherwise, it will have to be refilled on a regular basis as it drains. Allow time for the tank to cool. Duration of this process is dependent on the size of the tank, degree of insulation, and temperature of water in the tank when it is first filled with water. Some people simply need to wait a few hours while others require many days. Some people leave it overnight
  • Others don’t. Connect the hose to the drain valve, which is a spigot located at the bottom of the hot water tank, and run the other end to a location where it is appropriate to allow the water to flow out of the tank. Because the water will contain sediment, it should not be discharged into a garden or any other area where there is plant material that may be sensitive to calcium. Turn on a hot water tap somewhere in the house to start the process. It will serve as a relief valve, allowing the water to flow more quickly from the drain spigot
  • And Open the drain valve by turning it on. Allow it to run until the tank is completely depleted. The majority of these spigots are angled and poorly engineered to remove sediment—remember, they were created by hot water tank manufacturers, who are far more concerned with sales than with proper water heater maintenance
  • Turn on the water supply to the tank while the drain spigot is still open to flush out any residual sediment from the tank. At this point, the valve may be closed to enable for the tank to begin heating up as the water flows clean from the end of the hose
  • Close the hot water faucet (the only one that is currently open in the house)
  • After filling the tank to capacity, re-energize the water heater

This simple procedure may extend the life of a water heater by several years. If you notice a leak or any other sort of problem while draining the water heater, or if you’d like to have a professional drain the tank, please let us know as soon as possible.
