Why Drain 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.


  • Working with extremely hot water is a must for this procedure. For safety reasons, it’s a good idea to switch off your hot water heater several hours before you start so that the water in the tank can cool. 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 from above.

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 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 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.

Frozen Hose Bib: How to ThawPrevent Major Water Damage

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.

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. It is important to note that having a lengthy, hot shower is a good approach for expediting this stage of the draining process!

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.

To Drain or Not to Drain-Your Hot Water Heater

We are officially in the midst of spring cleaning, as Phoenix residents prepare to spend the summer months hunkered down in our air-conditioned homes. “Do I really need to dump my hot water heater tank every year?” is a topic we are asked rather frequently. (The use of a whiny voice is entirely optional.) In all seriousness, it is dependent. Each hot water tank is unique, dependent on a variety of circumstances that include not just where you reside in the Valley, but also whether or not your tank is equipped with a hydro-jet to decrease silt accumulation.

  • The availability and quality of these services are highly dependent on where you reside.
  • Conclusion: You will not know how often to drain your hot water tank unless you actually do it in order to determine how much sediment has accumulated in the meantime.
  • In the same period of time, other tanks can build several inches of silt, which is sufficient to clog the spigot.
  • Some hot water heater manufacturers advocate removing just approximately a gallon of water once a month, while others recommend draining it more frequently.
  • What exactly happens?

It might be a small amount or a large amount. The silt interferes with the tank’s capacity to heat the water, causing it to work harder to heat the water as a result. The following is a broad outline of how to go about it. Specifics can be found in your hot water heater’s owner’s manual:

  1. 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. Turn off the electricity to the hot water heater if it is not already off. The fact that you must turn off your hot water heater is not optional since you risk destroying your hot water heater. The water supply to the hot water heater should be shut off. Otherwise, it will have to be refilled on a regular basis as it drains. Allow time for the tank to cool. Your tank’s size, insulation level, and water temperature when you first started all influence how long it will take to complete this process. Some people simply need to wait a few hours while others require many days. Others will have to wait until the next day. 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. You would be better off not emptying the water into your garden or any other area where you could have plant material that is sensitive to calcium because the water will contain sediment. Start by turning on a hot water tap anywhere in your residence. It will serve as a relief valve, allowing the water to flow more quickly from the drain spigot
  2. And Open the drain spigot by turning it on. Allow it to run until the tank is completely depleted. It’s important to note that the hot water tank manufacturers, who are far more concerned with sales than with proper hot water heater maintenance, built the majority of these spigots to be angled and poorly constructed to remove the silt. Turn the water back on to the tank while keeping the drain spigot open to remove any leftover silt from the system. It is OK to close the valve to enable for the tank to heat up once all water has been removed from its end of the line. Removing your hands from the hot water faucet (the one you opened in your home)
  3. The water heater should be turned back on after the tank is completely filled.

Why Should a Pro Drain and Flush Sediment from Your Building’s Water Heaters?

You are undoubtedly already aware that your HVAC system need regular preventative maintenance in order to continue to operate effectively and efficiently. But there are other mechanical systems in your business property that would benefit from the attention of a trained specialist as well. You’ll want to make sure your water heater is one of the most crucial of them. It is common for commercial buildings to utilize large amounts of hot water, which results in water heating accounting for a major portion of your monthly running expenditures.

  1. Here is a quick explanation of water heater maintenance, as well as the reasons why you should have a professional drain and cleanse the system on an annual basis.
  2. Calcium and lime are two of the most prevalent types of sediment that occur in the environment.
  3. Minerals and sediment accumulate on the bottom of your water heater’s tank the majority of the time.
  4. In essence, the sediment layer acts as an insulator for the tank’s bottom.
  5. Because you want warm water, you waste energy and spend more money than you should.
  6. Hot water that is cloudy, filthy, or turbid might be a good indicator of a problem.
  7. The sediment and minerals in your water supply can also accumulate inside the pipes of your water heater, reducing the amount of water that can flow through them.

Excessive accumulation of material within the pipes may result in their failure, such as cracking or bursting.

If you have what is often described as hard water in your region, which is water that has a high concentration of minerals, your water heater may require more frequent maintenance to keep it operating at peak performance.

Your plumbing specialist will be well-versed in the issues that might arise as a result of sediment and mineral build-up in a water heater.

For these reasons, it is preferable to contact a professional to empty and flush the tank of your water heater.

Your plumbing technician will next connect a supply pipe to the tank in order to refill it with water once more.

As soon as there is no more debris seen flowing out of the drain hose, the tank has been thoroughly cleaned and is ready to be placed back into use.

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.

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.

This Might Also Be of Interest to You: What is the proper way to turn on my water heater? Fortunately, it’s a simple job that can be completed with only a few simple instruments.

Learn how to empty your water heater in a safe and effective manner.

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.

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. It is much more vital to wait for the water to cool down before you begin if using a bucket since you may get splashed during the procedure if the water is too hot.

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.

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. After that, you should be able to enjoy another year or two of warm water provided by a well running unit without any further complications.

How to Drain Your Hot Water Tank (And Why You Should!) — Multi Trade Building Services

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.

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.

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. Finding the drain valve on your tank should be your first order of business. It resembles a little outdoor faucet in terms of size and appearance. The water should be allowed to drop to ambient temperature before being drained, thus we highly advise that the gas or electricity to your hot water tank be shut off. It will take several hours to do this task properly. However, while it is not required to drain your tank, doing so is a good idea for safety reasons. In the event you decide not to wait the necessary amount of time to allow for complete cooling of the water in your water heater, keep in mind that all of the water that comes out of the drain valve will be extremely hot.

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 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:

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.

Should I Drain My Water Heater Periodically?

Flushing out the lime and other particles in the water heater tank on a regular basis helps to increase the efficiency and longevity of the heater. Sediment can build up and calcify in water heaters that have been ignored, making it difficult to clean out. Eventually, this can get so severe that the entire unit may have to be replaced. However, by flushing your tank on a regular basis, you can avoid silt from causing difficulties. – Mineral content is present in all water to varying degrees. Because limestone is abundant under the surface of the groundwater, if you live in a location with a lot of limestone beneath the groundwater will pick up calcium and magnesium deposits, resulting in “hard” water.

Before You Begin a Water Heater Flush

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.
