How Long Does It Take To Drain A Hot Water Heater

How Long Does a Water Heater Take to Drain?

Draining a water heater is something you should do once a year to ensure that your hot water heater is operating at peak performance levels. The draining procedure is short, generally no more than 15 minutes, depending on the size of your tank, but prep work takes a bit longer, and the full operation may require approximately a day.

Tip

If you want to thoroughly empty your water heater, you should plan on spending many hours or a whole day. Water heater flushing may be necessary more frequently if you have hard water, perhaps twice a year or more. In order to prevent calcium and magnesium accumulation in your water softener, you should drain the tank at least once each year.

Preparing to Drain Water Heater

If your water heater becomes clogged, you’ll need to drain it as quickly as possible in order to continue to deliver hot water to your home. It should be drained once a year or more frequently if you have hard water, if not already done so. In order to begin, the hot water heater must first be turned off with the electricity turned off. This is a really important phase. If you have a gas water tank, instead of turning off the circuit breaker, you’ll switch the gas valve off and into pilot mode to conserve gas.

  1. Leaks are prevented by using a hose with a rubber gasket.
  2. Those circumstances necessitate the use of two hoses: one to connect to the pump and another to connect to the outside.
  3. Then, switch off the water supply to the tank, if necessary.
  4. It will be necessary to allow the water to cool.
  5. If you want to speed up the process, take a lengthy, hot shower.

Draining the Water Heater

As soon as the water has cooled, attach the hose to the drain valve and stretch the line to a location where you can drain it. Because of the particles in the water, a garden hose is not a good option. While you may use a bucket and empty the bucket as needed, the procedure will need you to start and stop it at various points. Close the valve that controls the cold water supply line. After that, you’ll want to make sure the pressure release valve is working properly. Placing a pail beneath the valve and listening for air and looking for water will help you identify the problem.

  • Unless there is a hissing of air or a leak of water, it is possible that this may require replacement.
  • Open the water heater drain valve and allow the water to drain entirely from the tank.
  • Depending on how much sediment has accumulated, this might take a short period of time or a long period of time.
  • When the water in the drain flows clean, you have completed the draining process.
  • You can clean the tank with white vinegar if necessary.
  • Now it’s time to put everything back together again.
  • Before turning on the power or gas, make sure the tank is completely full.

Because you have removed the sediment from your water heater, it should operate more effectively, resulting in you using less energy to heat the water. Every year, cleaning your water heater will help you save money on your water costs.

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 emptying a water heater? For the simple reason that it prevents the accumulation of mineral deposits within the water heater.

  1. A very thick, crusty coating can form at the base of a gas water heater, and the heating elements 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. However, there is something that many people are unaware of: If your water heater hasn’t been flushed for years, some plumbers advise you not to flush it since this might ignite leaks.
  5. When you flush away the sediment, you run the risk of removing some of the leak-prevention measures in place.
  6. Locate and contact a local water heater repair professional.
  7. The cost of draining and flushing a water heater varies depending on the manufacturer.
  8. The following graphic illustrates the construction of electric and natural gas water heaters.
  9. The drain valve looks like a little outdoor faucet.
  10. 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.

  1. 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).
  2. The supply to this water heater is controlled by a lever valve.
  3. 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.
  4. Fill the tank with water by connecting a hose to the water heater’s drain valve.
  5. As the water drains, this prevents a vacuum from building in the system.
  6. To avoid scorching, exercise extreme caution.
  7. 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

It may be necessary to open the pressure-relief valve if your water heater is not draining properly or at all when you open the drain valve (see the illustration at the top of this page). This has the potential to dislodge the vacuum that is keeping the water trapped. In most cases, if the water heater won’t drain or drains slowly, the problem is most likely caused by a buildup of silt in the water heater’s tank. In some cases, sediment can jam the drain valve on a tank-type water heater. You may drain a blocked water heater through the drain valve by following the methods outlined below.

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).

It takes relatively little time and only a few simple equipment to drain a water heater and remove sediments, making it an excellent do-it-yourself project.

Is it too late to drain my water heater?

If your water heater is 5 years old or younger, you should consider replacing it. Don’t hesitate to make the repairs; you should still have a few years of life left in the tank. This bad boy will not let you down even if you are three years late in doing your yearly water heater drain procedure.

How much does it cost to drain a hot water heater?

It will cost around $200 to have your water heater flushed and drained by a professional. However, depending on the season, you may be able to score a good price. (The fall season is a favorite period for this.) If it has been a long time since your water heater has been cleaned and drained, you might consider hiring a professional to complete the task for you.

How much water should you drain from hot water heater?

Connect a hose to the water heater’s drain valve and route it to the location where the water will be drained. Open a hot water faucet in a convenient location around the house. Open the water heater drain valve (caution: hot water will be released). Close the valve after flushing three to four gallons (if draining, continue until empty).

How often should a hot water heater be drained?

According to both BobVila.com and The Family Handyman, it’s a good idea to empty your water heater at least once a year in general.

If you reside in a hard water location, on the other hand, Angie’s List suggests that you may need to empty your water more often.

How do I release the pressure on my water heater?

When using most systems, just raising the valve until the associated brass stem rises is sufficient to release pressure from the water supply. The hot water will surge out of the pipe towards the bottom of the water tank as soon as you complete this step. Then, to close the valve and stop the water flow, pull the lever all the way down again.

How do you break the sediment out of a hot water heater?

Water Heater Powered by Electricity Open a hot water faucet in your home just a smidgeon more than usual. Then open the drain valve and allow all of the water in your water heater to drain out. Turn on the cold water supply while the garden hose is still attached and the drain valve is left open to allow the water to flow. Allow water to circulate through the device to flush out any silt that may have accumulated.

How long does it take to drain 30 gallon water heater?

How do I know if my hot water heater is sedimented?

Symptoms of Sediment in Your Hot Water Heater There is no hot water available. The temperature of the water changes. The tank is making popping or rumbling noises at this time. Your hot water appears to be rusted and has a foul odor. Some minor leaks have been discovered around the water heater drain valve. It takes a long time for water to heat up.

Where is the drain valve on a water heater?

An inlet valve for the heater tank should be located at the top of the heater tank’s line. Alternatively, you can turn off the main water supply valve to your house.

What happens if you don’t drain your water heater?

How Does It Affect My Water Heater If I Don’t Flush It? It is possible that leaving sediment buildup in your water heater would not only make it work harder, but it may also result in some major complications. Things like a ruptured pipe, a lack of water pressure, or even the failure of the tank itself are all possibilities.

How long does it take for a new hot water heater to fill up?

It takes an ordinary gas heater between 30 and 40 minutes to completely heat the water in its tank, depending on the model.

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. 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.

Basic Water Heater Maintenance – Draining the tank

Re-start the water supply after the water flowing out of your tank looks to be clear. Afterwards, switch on the cold water supply by closing the water heater’s drain valve.

Make careful to return the pressure-relief valve to its original position as well as the other valves. After that, turn off all of the hot water taps in your home (which you had previously turned on in Step 3) and, lastly, turn on the water heater, which should now be clear of sediment.

Step 1: The most important step, that is most often overlooked (Orange)

Electric Water Heater (Left Side): Turn off the power to your electric water heater by turning the breaker to the off position. Gas Water Heater (Right Side): Turn off the gas water heater by turning the breaker to the off position. You may have been fortunate enough to have a genuine outlet installed by your builder, electrician, or plumber, and you will be able to simply unplug it. If you neglect to turn off the power to the heating element(s), it is probable that they will be destroyed by the high temperatures.

Using the pilot setting at my home is no problem, while in a customer’s home, I would cut off the gas not just at the thermostat, but also at the main supply line.

Step 2: Turn off the cold water supply to the tank.

Here are a few simple comments about this: when hot water is pushed through inexpensive hoses, they tend to become very soft and are more likely to leak. Make certain that the water is routed through the home to a handy drain, sump pump, or other drainage system, rather than directly into your crawl space. In certain circumstances, if a drain is entirely unavailable or the water heater is located at a higher elevation than the drain, you may always resort to the bucket brigade or purchase a pump to assist in propelling the water out and away from the home.

Step 4: Time to drain the water

First, turn on a nearby hot water faucet, and then turn on the drain valve on your water heater to drain any remaining water. After you have completed this, you should turn on any hot water faucets that are nearby. Allow the tank to empty by opening the drain valve on the bottom of the tank. You may anticipate it to provide between 9 and 17 GPM, depending on the size of the hose and the pressure applied. As an example, if you have a 50-gallon tank, the water should be running at full pressure for 3 to 6 minutes; otherwise, switch on the cold water supply to the tank if the flow is sluggish, trickling, or otherwise ineffective.

Step 5: Rinse and Repeat

When the tank has been completely emptied, you can safely close the drainage valve. Reconnect the cold water supply and wait for the water heater to begin refilling itself. This will aid in the loosening of further silt in the tank. Once the tank is partially filled (about 1/2 to 2/3 full), allow the tank to fill partially before beginning the emptying procedure all over again if necessary. Once the water starts to flow, you may turn off the water supply valve at the appropriate location. This method may need to be repeated several times if there is a significant quantity of sediment remaining in the tank after the first time.

Step 6: The final few steps

It’s time to go backwards, or at least to retrace our tracks. To begin, you must first turn off the drain valve and detach the hose. Pour cold water into the tank by opening the cold water supply valve approximately halfway and allowing it to gently fill while checking for leaks. It is recommended that you remove the aerator from the open faucet and rinse it while this is taking place.

When hot water begins to flow from the hot water faucet, the tank is full, and you may turn off the faucet and re-install the aerator to finish filling it. Once you’ve turned on the cold water supply valve to its maximum capacity, you’ll be able to restart the electricity or gas to heat the water.

A few final notes:

It’s time to go backwards, or at least in reverse. It is necessary to disconnect the hose from the drain valve before continuing. Check for leaks while the tank slowly fills by opening the cold water supply valve approximately halfway and allowing it to fill gently. In the meanwhile, I recommend unscrewing the aerator on the open faucet and thoroughly cleaning it. When hot water begins to flow from the hot water faucet, the tank is full, and you may turn off the faucet and re-install the aerator to complete the process.

How Long Does It Take To Drain A Water Heater? [7 Amazing Unknown Factors]

TanklessWaterHeaterExpress is sponsored entirely by its readers. Because I am an Amazon Associate, I receive money when people make eligible purchases. Obviously, if your water heater is experiencing significant issues, it is imperative that you fix it immediately after emptying the water from the heater. However, if you are concerned about how long it will take to drain the entire water, it is important to note that this is dependent on the amount of water available as well as the plumbing structure of your property.

  1. Here is a reference on How Long Does It Take to Drain a Water Heater that you can go to for more information!
  2. Recognize the gravitational pull of water.
  3. As a result, the downward force is proportional to the rate of water flow and the inner diameter of the pipeline.
  4. If the surface is smooth, it will allow for a greater volume of water to be discharged more quickly, increasing the rate at which the water drains.
  5. If the flow rate is high, the gravitational force will be larger as a result.
  6. Inspect the pressure head for damage Next, there’s the pressure head, which is a very essential consideration.
  7. Per the calculation, 1 foot of elevation decrease equals 0.4332 pounds of pressure head.

As a result, the greater the pressure head, the better it is for both the source and the output of the system.

Be familiar with the pipe material.

There are two factors to consider, the internal diameter and the outer diameter, which are as follows: It, combined with the material from which the pipe is constructed, defines the volume capacity of the pipe.

If it is low, on the other hand, the water flow rate will increase.

As a result, the one-inch pipe can provide you with both high force and individual volume to drain down the pipe, making it more suitable and convenient.

Have a basic understanding of hydraulics.

While the tank is being drained, check to see that there are no airlocks that need to be addressed.

As a result, the drain flow is stopped in this situation.

To avoid any form of pressure, be certain that there is no airlock within the pipe. In addition to this, the hydraulics has an impact on the flow rate of the pipe when it is vertical. You will need to overcome the airlock that has formed in your system if at all possible.

Other Factors Affecting the Flow

In addition to these four criteria, there might be a variety of other factors that influence the period of flow. You may view them by clicking on the links below: 1. The first thing to consider is the amount of water available. If you have a tiny tank, it will just take you 1-2 minutes to completely drain it out. However, if the tank is larger, the process may take longer. Another thing to consider is the formation of sediment in the drainpipe. If there is more sediment, it will obstruct the flow rate and cause it to take the longest possible amount of time.

If your heater is located on the second floor and the majority of your faucets are located in the first level, cleaning up will take longer.

Frequently Asked Questions

The draining of my water heater is taking an unusually lengthy time. Q1. A1.The accumulation of sediment in the drain pipe has the potential to lower the flow rate of water via the drain pipe. In general, rust and debris have a difficult time flowing out of the pipe. As a result, it may take longer to drain the water. The removal of material prior to the drain is quite vital in such a circumstance. Q2. What is the fastest way to empty the water heater? To quickly empty your water heater, try attaching a temperature-pressure release valve to the tank.

  1. The result is that water drains out more quickly when pressure builds in the system.
  2. What is the approximate time required to empty a 50-gallon water heater?
  3. In most cases, the flow rate is around 10 gallons per minute.
  4. We’ve just published a new post about the best 50 gallon gas water heater on the market.
  5. A4.A high-pressure release valve is installed in the majority of the 40-gallon water tank.
  6. As a result, it will take around 4 minutes to completely empty the tank of water.

Conclusion

The amount of water that drains from the tank is dependent on a number of parameters that must be monitored. However, if you want your heater to function effectively on a consistent basis, you will need to maintain it. Consequently, make certain that the drain pipe is clean and that it is properly attached to the heater so that it does not interfere with the drain pipe.

How to Drain a Water Heater

It is necessary to maintain track of a number of variables to ensure that water drains from the tank.

Maintenance is necessary, though, if you want your heater to function correctly at all times. Keep the drain pipe clean and well connected to the heater in order to prevent the drain line from becoming clogged with debris.

  1. If you have an optional recirculation pump, unhook it from its power supply. If you do not have an optional recirculation pump, turn it off. If this is not the case, go to the next step. Turn off the heat source by doing so: When using a gas water heater, be sure that the burner control knob is on the “pilot” position. It is simple to switch off the electricity to your electric water heater by disconnecting it or turning it off in your electrical panel or circuit breaker
  2. However, you must be careful not to overload the system. Immediately turn off the water supply: The cold water line that is linked to the top of the water heater tank is usually equipped with a valve, which is standard on most water heaters. If this is the situation with your system, switch off the cold water supply valve at this location to prevent further damage. However, if you do not have access to this feature, find your home’s main water line and turn off the cold water from there. Connection of the drain hose to the water heater drain valve: Screw your hose (a garden hose will work) into the water heater drain valve, which is located at the bottom of the tank, and lead it to the drainage region of your choosing. It is possible to drain the unclean water into your driveway, a floor drain, or any other location that feeds to a sewer or the public sewage system. If you don’t have any of these solutions, a bucket will do in this situation. The color of the draining water and the quantity of debris that drains out of your tank may also be used to determine the degree of the corrosion that has occurred within your tank when you use a bucket to monitor it. The drain valve should be opened now that the hose has been connected to the water heater. The water in the tank should now be released through this valve. You may be able to complete this task by hand, but a screwdriver may be required at times to aid you in the process. The water will be quite hot, so proceed with caution. Air should be allowed to enter the tank at this stage since the water will be draining from your hot water tank extremely slowly, if at all, owing to the vacuum that exists inside the tank. In order to break up the vacuum and get the water flowing again, there are a few of ways to get air in.
  1. If your unit is equipped with a pressure relief valve that is linked to the tank, you can open the valve to allow for the introduction of necessary air. If your pressure relief valve does not vent, you may also allow air to enter the system by loosening the piping that links to one of the water lines at the top of the water heater
  2. However, this will cause the water heater to overheat. Finally, turning on the hot water tap on the faucet that is nearest to your water heater is a straightforward way to relieve pressure from the system.
  1. Allow the tank to completely drain: Once again, be wary of the hot water that is departing the tank. Allow all of the water to drain out of the tank entirely before continuing. According on the size of the tank, this might take anywhere between 5 and 10 minutes. Flush the tank: If you had any piping at the top of the water heater loosen in order to allow air to enter the system, be sure you tighten it back up when you are through. Then, re-open the water heater valve that was closed in step 4 to allow the water to flow again. Alternatively, you may use your palm to hit the outside of the tank (with caution!) in an attempt to break up any leftover silt. Pay attention to the color of the water that is coming out of your hose, and leave the hose running for as long as necessary for the water to be clean and clear. As a general guideline, you should leave the water running for around 5-7 minutes regardless of whether or not your water heater tank is dirty to be absolutely certain it is completely clean. Close the drain valve and remove the hose as follows: Close the drain valve using your hands or with a screwdriver if necessary. In order to avoid serious leaks, make certain that the valve, as well as everything else you detach and reconnect throughout this process, is completely tightened. You may then disconnect the hose once the drain valve has been properly closed. Open all hot water faucets in your house to remove any trapped air that may have entered the water lines while draining the tank: Next, go inside and open all hot water faucets in your home to release any trapped air that may have entered the water lines while draining the tank. Continue to run the hot water for about 4-5 minutes, or until all of the air has been expelled from the water supply pipes. As soon as the water begins to flow normally and without any spurting or halting, you will be able to know that this has been completed. Restart the recirculation pump by doing the following: The moment has come for you to plug in your recirculation pump, if you had it disconnected before starting the operation
  2. Reconnect the heat source by following these steps: At long last, you can re-ignite the burner on your gas water heater, or you may reconnect the electrical system to the wall outlet or switch it on via the electrical panel/circuit breaker

Again, be wary of the hot water that is departing the tank while allowing it to drain totally. Allow all of the water to drain out of the tank entirely before continuing. According on the size of the tank, this might take anywhere from 5 to 10 minutes. ; Flush the tank: If you had any piping at the top of the water heater loosen in order to allow air to enter the system, be sure you tighten it back up when you’re through. Next, re-open the water heater valve that was closed in step 4 to re-start the water flowing again.

Examine the color of the water that emerges from your hose and let it run for whatever long it takes to produce clean and clear water at the end.

In order to avoid serious leaks, make sure that the valve, as well as everything else you detach and reconnect throughout this process, is completely tightened.

Turn on the hot water heater taps: After that, you’ll need to go inside and turn on every hot water tap on the faucets in your home to remove any air that may have gotten into the water lines while you were removing the tank from the water heater.

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
