How to Flush or Drain a Water Heater Tank
Listed below are the procedures to be followed while flushing or emptying a water heater. This video provides a wonderful summary of the subject: To turn off the gas or electrical power to the water heater, depending on whether it is a gas or an electric water heater, follow these steps: The “Pilot” setting on a gas water heater is as simple as turning the gas control to “Pilot.” 2 Turn off the cold water inlet valve, which is responsible for regulating the supply of water into the tank.
Make certain that this is the incoming cold water valve and not a valve for the outgoing hot water supply (the pipe should be cold).
The supply to this water heater is controlled by a lever valve.
3 Connect a hose to the machine.
Water Heater Won’t Drain
If your water heater is draining slowly or not at all when you open the drain valve, you should try opening the pressure-relief valve to see if it helps (see the illustration at the top of this page). This has the potential to dislodge the vacuum that is keeping the water from leaving. In most cases, if the water heater won’t drain or drains slowly, the problem is most likely due to an excessive amount of sediment building up in the water heater. The drain valve of a water heater can become clogged with sediment.
First Steps in Breaking a Drain Valve Clog
1Detach the water heater from the mains. Depending on whether the water heater is gas or electric, switch off the gas valve or the circuit breaker that supplies electricity to the water heater. Secondly, connect an outside hose to the drain valve and run it outside, making sure that the hose’s end is below the level of the water heater. Turn on a hot water faucet someplace in the home or open the pressure-relief valve on the water heater to dislodge the vacuum that has built up inside the tank.
If the water flows freely, the valve is functional.
4 In the event you believe that the drain valve has become clogged, you can attempt to shoot water and air bubbles back into the tank by repeatedly walking on the hose a few feet away from the tank.
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

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 water has an impact on the downward force.
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.
This permits the water to freely flow due to the pressure of the air coming from the top. The result is that water drains out more quickly when pressure builds in the system. This makes it possible to drain your water quickly. What is the time it takes to empty a 50-gallon water container?
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 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.
Also, it is a significant element in influencing the length of time required to empty a water heater.
A large-diameter drain valve will increase tank capacity in the same way.
How Long Does a Water Heater Take to Flush
The process of flushing a water heater is distinct from the process of emptying one. To begin with, you may cleanse your water heater if you notice that the water is becoming stale. However, emptying the water heater should only be done every six to twelve months, depending on the model. Second, emptying the water heater necessitates the shutoff of the cold water supply line, which allows you to empty the contents of the water heater tank. Using the flushing function, on the other hand, the water supply line must be open and the drain port must also be open.
The disadvantage of taking this strategy is that you will be unable to inspect the interior of your water heater tank since it will be continually filled with water.
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. Initially, cold water is pumped into the tank, where it is heated by a mechanism to the proper temperature before being released into a variety of faucets, plumbing appliances, and other water fixtures. According to the United States Geological Survey, water is never completely clear or transparent. 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 method does not cleanse the water in the process.
These dense particles sink to the bottom and sides of the tank, where they accumulate over time.
For instance, high calcium carbonate levels are harmful.
How Frequently Should I Drain a Water Heater
As previously stated, sediments collect at the bottom of the tank over time. A water softener, sediment filter, or water filtering system can reduce the need to empty your water heater to as little as ten to twelve months per year if you have one. It is the calcium carbonates in the water that cause water softeners to function. These compounds, as well as other hard minerals, have the potential to clump together and adhere to the interior walls of plumbing systems, including those in your water heater.
A sediment filter, on the other hand, only eliminates particles that are bigger than the pore size of the device.
Smaller particles can still travel past the filter and end up at the bottom of the tank, causing it to overflow.
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.
How long does it take to drain an 80 gallon hot water heater?
It takes around 20-25 minutes to drain the whole amount of water from the heater and complete the entire operation. However, the length of time it takes to heat up varies depending on the size of the heater. between 3 and 6 minutes In addition to the time mentioned above, how long does it take to empty a 40 gallon hot water heater? I just switched off the main valve, so we’ll see whether that accomplishes the desired result. An associated downtube should be coupled to a pressure release valve for safety.
The time required to drain 40 gallons is 45 minutes, or less than a gallon per minute.
Allowing water to flow out of the tank is accomplished by opening the spigot’s valve.
This permits some air to enter the pipes, which causes the water within the tank to flow more quickly.
- Turn off the water heater and the cold water valve
- 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.
How long does it take for a 50 gallon water heater to drain?
Aside from the amount of time it takes to empty your water heater, the size of the tank itself determines how long it will take. With a 50 gallon tank and a hose pressure that permits 10gallons per minute (GPM) of water to flow through it, you may anticipate the tank to be completely drained in around 5 minutes. I’ve now switched off the main valve, so we’ll see if that solves the problem or not. You should have a pressure release valve with a downtube installed to your system before starting.
The time required to drain 40 gallons is 45 minutes, or less than a gallon per minute.
It is possible to examine how much silt ends up in and around the drain valve.
The silt interferes with the tank’s capacity to heat up and causes it to overheat.

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 water heater to drain?
Open the water heater drain valve and allow the water to drain entirely from the tank. Once the water has been emptied from the tank, which should take no longer than 15 minutes, switch on the cold water supply valve to assist in flushing out the sediment that has accumulated in the tank. Depending on how much sediment has accumulated, this might take a short period of time or a long period of time.
How many gallons of hot water does a 40 gallon water heater use?
The amount of hot water you would need would be more than 41 gallons, and if that’s the case, a 40-gallon water heater may not be sufficient for your needs. However, if more people in your home take showers at the same time, or if you take longer showers, you may find yourself running out of hot water very quickly.
How long does it take for a 40 gallon water heater to recover?
Approximately two hours are required for the recovery of a 40-gallon electric water heater. It may be necessary to upgrade your 40-gallon water heater to a larger one if the recovery time of your water heater causes you to miss out on hot showers on a regular basis. A 50- or 80-gallon water heater may be more appropriate. One additional option is to use a tankless water heater, which warms water only when it is required.
Is it OK to drain a gas water heater?
It is not a good idea to empty a water heater that is currently in use. If you have a gas-powered water heater, you may set the switch to “pilot” to keep the pilot light on while turning off the water heater’s heating element.
How long does it take to drain a 50 gallon water heater?
A 50-gallon tank should be able to hold its maximum pressure for 3 to 6 minutes if the water is running continuously. Activate the cold water supply to the tank if the water flow is sluggish or absent. The following should, hopefully, assist you in clearing the obstruction. After you’ve finished waiting and the tank has been completely emptied, turn off the drainage valve. The amount of hot water you would need would be more than 41 gallons, and if that’s the case, a 40-gallon water heater may not be sufficient for your needs.
Why is my 40 gallon water heater too small?
Trying to reduce your hot water use but finding that your 40-gallon water heater is simply not cutting it may indicate that your water heater is simply too small for your need.
Following are some estimates that will give you an approximate idea of what size water heater you’ll need based on the size of your family:
How do you drain a hot water heater?
Opening up your hot water faucet and then the drain valve on your water heater should be the first two steps. After you’ve completed this, you should turn on the hot water side of any faucets you may have. Second, open the tank’s drain valve and allow the tank to drain completely to remove any remaining water.
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.
In my home, I have no difficulty just turning the gas to the pilot setting, however in a customer’s home, I will turn the gas off completely, including the pilot setting.
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.
Turning on the cold water supply should, in theory, assist you in blasting through the blockage faster.
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!

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.
The fact that you saw clean-looking water pouring out of your tank does not necessarily imply that you are in good standing with the authorities. It is necessary to drain a water heater for longer periods of time than five minutes in order to eliminate sediment.
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.
(Keep in mind that if you open the pressure-release valve, the pressure will be released.)
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.
Water Heater Recovery Heat Up Times Comparison Chart
Recovery of Waste Water from Water Heaters Heat Up Times Compared to One Another Time Required for Water Heater to Come to Temperature There isn’t much that can ruin your day quite as quickly as taking an ice cold shower, and if you have the wrong hot water heater, this might become your new normal very soon. In the event that your current heating unit fails on you, don’t let your stress over the situation lead you to make the wrong choice for a replacement. Prior to selecting a hot water heater, take into consideration how long it will take for the water heater of your choice to heat up completely.
If you want to run a large amount of hot water at the same time, you’ll need a more powerful system than if you merely want to take a hot shower on a regular basis. So, how long do you think it will take?
| Water Heater Type | Time to Heat Back Up |
| Gas – Conventional Tank | 30-45 mins |
| Gas Tankless | 0 mins |
| Electric – Conventional Tank | 60-80 mins |
| Electric Tankless | 0 mins |
Water Heaters Powered by Natural Gas Specifications for a Gas Conventional Water Heater Once the water is in the tank, the normal gas tank water heater will take 30 to 40 minutes to heat it up to the desired temperature. When new water from your water supply is fed into the tank, this early heat up occurs as a result of the incoming water. Some mathematical calculations are required to provide a more specific explanation of why this takes 30 minutes. The size of the heater’s tank is obviously important, since more water will take longer to heat than a smaller tank.
In simple terms, a BTU is the amount of heat required to elevate one pound of water by one degree Fahrenheit in temperature.
For example, the average hot water heating unit tank holds 40 gallons of hot water.
A gas tank hot water heater will take roughly 40 minutes to warm up new inbound water for the very first time.
Specifications for an Electric Conventional Water Heater When compared to gas tank hot water heaters, electric tank hot water heaters often require double the amount of time to heat water. Electric components, while often more cost-effective, are just incapable of matching the high performance of gas-fired systems. It would take approximately one hour for an electric hot water heater to heat the 40-gallon tank shown above from the moment brand-new water is introduced into the system. As a result, homes with higher water needs are more likely to choose for a whole-house gas tank water heater rather than an electric model.
A tank hot water heater that uses electricity takes 60-80 minutes to heat water, but a tank hot water heater that uses gas takes 30 minutes.
- Temperature of the incoming water-For both tankless and tank-style hot water heaters, the temperature of the incoming water will determine how long it takes for the water to heat up to the desired temperature. Due to the fact that tank heating systems conserve water while still maintaining a constant temperature, the incoming temperature should not have a significant impact. Tankless heating systems, on the other hand, supply incoming water as needed only a few seconds before it is released from the faucet. This suggests that if the groundwater temperature level is really low, the water may not heat up as quickly as it otherwise would. When the ambient temperature in the room or area where the heaters are housed is excessively cold, both types of heaters might be adversely affected. Even while water heaters appear to be relatively simple when compared to other household mechanicals, they often offer more configuration options.
