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. Depending on the size of your tank, the draining procedure can take as little as 15 minutes, but the prep work might take several hours, and the entire operation could take as long as 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 you want to thoroughly empty your water heater, plan on spending many hours or a whole day. It may be necessary to cleanse your water heater more frequently if you have hard water. Water softeners should be drained at least once a year to prevent calcium and magnesium accumulation from accumulating in the system.

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.

  1. Unless there is a hissing of air or a leak of water, it is possible that this may require replacement.
  2. Open the water heater drain valve and allow the water to drain entirely from the tank.
  3. Depending on how much sediment has accumulated, this might take a short period of time or a long period of time.
  4. When the water in the drain flows clean, you have completed the draining process.
  5. You can clean the tank with white vinegar if necessary.
  6. Now it’s time to put everything back together again.
  7. 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 reduces the accumulation of mineral deposits within the water heater.

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

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).

How to Flush a Water Heater Video

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

Back-Flushing a Water Heater Step-by-Step

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

7Remove the hose from the water faucet and attempt cleansing the tank once again with the hose.

How to Replace a Water Heater Drain Valve

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

  • Water heaters have a drain valve that is positioned at the bottom of the tank.
  • Having a helper use buckets to collect and dump water that is flowing from the water heater while you remove and replace the valve will be the norm in most circumstances, but it may be necessary in other cases.
  • Expect to be drenched as a result.
  • This will take some time.
  • To do this, switch off the cold-water supply to the water heater and ensure sure no one comes into contact with any of the hot water fixtures or appliances in the house while the valve is being changed.
  • After that, turn off the circuit breaker on an electric water heater or the gas valve on a gas water heater to prevent the water from reheating further.
  • Allow for the water in the water heater to drop down to a safe temperature before using it once more.

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

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

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

Remove the valve completely from the system.

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

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.

  • Here is a reference on How Long Does It Take to Drain a Water Heater that you can go to for more information!
  • Recognize the gravitational pull of water.
  • As a result, the downward force is proportional to the rate of water flow and the inner diameter of the pipeline.
  • 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.
  • If the flow rate is high, the gravitational force will be larger as a result.
  • Inspect the pressure head for damage Next, there’s the pressure head, which is a very essential consideration.
  • 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.

What Would Bob Do? Draining a Water Heater

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

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

STEP 1: Check the pressure-relief valve.

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

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

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

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.

Using a long screwdriver or dowel to dislodge silt after the valve has been removed may be beneficial. 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 long does it take for a 50 gallon water heater to drain?

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.

  1. Turn off the water heater and the cold water valve
  2. Turn off the faucet. Allow the water to cool. The drain valve on the side of the tank should be connected to a drain or a garden hose. Placing the hose’s other end in a bucket or drainage system Turn on a faucet (or two), if possible. Turning on the drain valve will begin the process of draining the tank.

Basic Water Heater Maintenance – Draining the tank

If you want to be honest with yourself, you may acknowledge it – and I will, in fact, begin by admitting that I haven’t emptied my water heater in several years. I’m fortunate in that the water is not very “hard” where I live. Sand, minerals, and other materials contained in water are what is referred to as “hard” water. As a result, if I were still a resident of Phoenix, I would be in for some major difficulties. While little amounts of silt that settle to the bottom of the tank are not a major concern, over time, they can accumulate and become a problem for the tank’s operation.

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.

A few final notes:

Is it really necessary to clean out your tank once a year? The practice is recommended, particularly if you have well water or naturally hard water. In the case that you are following our monthly maintenance checklists, we did mention it as an annual item merely because it is simpler to recall than the ever common “Did I complete it last year or not?” question. When using an electric water heater, remember to cut off the power before draining the water since even a partial drain might expose the higher heating element to the air and cause it to malfunction permanently!

How to Drain a Water Heater

Water heaters are one of the most often used equipment in our houses, and they provide a variety of functions. Showering and bathing, doing laundry, cleaning dishes, and especially washing our hands are all made easier with their assistance. Over time and with usage, water heaters, like any other device, begin to develop issues that must be dealt with. In the bottom of the tank, minerals that naturally present in the water (hard water), as well as sand and grit, settle out of the water. Sediment accumulation can lower the effectiveness of your water heater, as well as corrode the metal water heater itself over time.

It is important to note that because we rely on our water heaters so much, there are precautions we can take to ensure that they are not overlooked while planning our home improvement projects.

Consult with a qualified plumber for assistance).

Note that this service should NOT be conducted on any water heater that has not been purged within the last three years.

  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.

How Long Does It Take to Drain a Water Heater? – Average Time

As a first-time homeowner, do you have any questions about how long it takes to empty a water heater? Draining and flushing a water heater is a necessary operation for ensuring that the appliance continues to perform properly and efficiently. Water drainage aids in cleaning the tank’s inside, eliminating sediments and particles that have collected over time. Several factors influence the amount of time it takes to empty a water heater. As we study those aspects, we will be able to predict how long it will take you to drain your water heater.

Drain a Water Heater – How Long Does It Take?

Draining a water heater can take anywhere from five to fifteen minutes, depending on a variety of factors including the following. Capacity of the tank In general, the higher the tank size, the longer it will take to completely drain the water heater tank. Consider the following scenario: you have a 40-gallon water heater and a 60-gallon water heater. If all other conditions are equal, you may anticipate the 40-gallon appliance to drain more quickly than the other product in this situation. 2.

  1. Also, it is a significant element in influencing the length of time required to empty a water heater.
  2. A large-diameter drain valve, similar to tank capacity, will drain more water in a given amount of time.
  3. Recall that the 40-gallon water heater has a 12-inch drain port and the 60-gallon unit has a 1.5-inch drain valve in our hypothetical scenario above.
  4. Three, the amount of water pressure applied to the hose.
  5. Of course, this is only true if the drain valves on both water heaters are the same size and the tank capacities are the same.
  6. If you have an 80-gallon water heater, anticipate it to drain between five to nine minutes.

It does not include the time spent on preparations and other associated tasks, though. Emptying a hot water heater rapidly may be accomplished by preparing all of the necessary materials and instruments ahead of time and following a systematic procedure of draining.

How Long Does a Water Heater Take to Flush

According to the criteria listed below, draining a water heater can take anywhere from five to fifteen minutes to complete. Capacities for storage tanks are listed in 1. In general, the higher the tank size, the longer it will take to completely empty the water heater system. Consider the following scenario: you have a 40-gallon water heater and a 60-gallon water heater on your property. If all other circumstances are equal, you may anticipate that the 40-gallon appliance will drain more quickly than the other product.

  1. The size of the drainage valve For the purpose of emptying and cleansing the tank, all tank water heaters feature a drain valve located at the tank’s base.
  2. You should follow this guidance for the optimal implementation in the situation of a drain valve not being available.
  3. For example, a drain valve with a 1-inch diameter will discharge more water per second than a drain valve with a 12-inch or 34-inch diameter will.
  4. As a result, the 60-gallon water heater will empty somewhat more quickly than the 40-gallon model in that situation.
  5. A hose with a flow rate of 10 GPM would force the water through the drain port more quickly than a hose with a flow rate of seven GPM.
  6. For the most part, water heaters drain at a rate of between nine and seventeen gallons per minute (GPM).
  7. Please keep in mind that these figures only indicate the actual draining of water from the tank and not the amount of water that has been drained.
  8. A hot water heater may be swiftly drained by organizing all of the supplies and tools ahead of time and following a well-organized drainage procedure.

How Much Time Do You Need to Drain a 40-gallon Water Heater

It is dependent on the drain port diameter and water pressure of a 40-gallon water heater to determine how long it will take to completely empty it. It’s important to know that the higher the water pressure, the faster the water will flow out of the drain valve, so keep this in mind. However, the diameter of the drain port must also be taken into consideration. With a bigger hole, you can empty the water heater much more quickly than with a smaller one.

As a result, depending on the water pressure and the size of the drain port, it might take anywhere from three to five minutes to drain a 40 gallon water heater. Keep in mind that this time does not include the preparation of the water heater for draining and the completion of the operation.

How Much Time Do You Need to Drain a 50-gallon Water Heater

It should take between three and six minutes to drain a 50 gallon hot water heater using our typical drain rate of nine to seventeen Gallons Per Minute (GPM). Once again, it does not take into account any additional actions associated with emptying the water heater. As a result, it is not uncommon to finish the entire operation in 15 to 45 minutes, depending on how quickly you work and whether or not the supplies or instruments required are readily available. I propose that you prepare your work space and materials ahead of time in order to expedite the whole water heater drainage procedure.

Why Drain a Water Heater

Water heaters with storage tanks are used in the industry. In the tank, cold water is pumped in, and a mechanism warms it up to the proper temperature before releasing it through various faucets, water appliances, and other plumbing fixtures.According to the United States Geological Survey, water is never completely clear. Sediments, suspended particles, and other things are constantly present in the water. Although the majority of the water that comes into our homes is treated at a water treatment facility, the technique does not cleanse the water.

  1. These dense particles sink to the bottom and sides of the tank, where they accumulate over time.
  2. For example, excessive calcium carbonate levels in the water can cause scale to develop on the heating element.
  3. That is why it is important to drain the water heater tank on a regular basis.
  4. After that, you may spritz it with water to verify that it is completely clean.

How Frequently Should I Drain a Water Heater

Water heaters with storage tanks are used in the industry. In the tank, cold water is pumped in, and a mechanism warms it up to the proper temperature before releasing it into various faucets, water appliances, and other plumbing fixtures.According to the United States Geological Survey, water is never completely clear. Sediments, suspended particles, and other things are constantly present in the water column. Water treatment facilities do a good job of treating the majority of the water that comes into our homes, but they do not purify the water, so there will always be things denser than water in the water we consume.

Water quality is affected by these compounds, but they can also have an influence on the operation of a water heater.

The water heater tank should be drained on a regular basis since it might harden and reduce the heating effectiveness of the water heater, resulting in longer heating times or lower water temperature.

It is possible to clean the tank’s inside and eliminate surface pollutants once it has been completely emptied. Afterwards, you may use water to thoroughly clean the surface.

Conclusion

It is necessary to have a basic grasp of a few things in order to answer the question “how long does it take to drain a water heater.” The size of the tank, the width of the drain port, and the pressure of the water can all have an affect on how quickly you can empty a water heater. In most cases, the actual tank emptying should not take longer than fifteen minutes, while additional activities may cause the entire operation to take up to 45 minutes in some cases.
