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 the water, causing it to work harder to heat the water as a result.
It takes around 20-25 minutes to drain the whole amount of water from the heater and complete the entire operation.
Ideally, with a flow rate ranging from 9 GPM to 17 GPM, for a 5—gallon tank, if the water runs out in full force, the tank will be completely emptied in 6-7 minutes, according to the manufacturer.
How to Flush Sediment from a Water Heater (with Pictures)
- 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 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 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.
Leaks are prevented by using a hose with a rubber gasket.
Those circumstances necessitate the use of two hoses: one to connect to the pump and another to connect to the outside.
Then, switch off the water supply to the tank, if necessary. Here’s where you’ll be spending the most of your time. It will be necessary to allow the water to cool. This might take a few hours or it could take a whole night. 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.
- Every year, cleaning your water heater will help you save money on your water costs.
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.
This can result in a loss of available water in both gas and electric water heaters, as well as a reduction in the transfer of heat to the water and the possibility of clogging the drain line, making it nearly hard to drain.
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
Just a few words on this subject: when hot water is passed through inexpensive hoses, they become exceedingly soft and prone to bursting. Don’t just dump the water into your crawl space; direct it to a handy drain, sump pump, or other location. It is possible to employ the bucket brigade or purchase a pump to help force the water out of the home in circumstances when a drain is entirely unavailable or the water heater is located at a higher elevation than a drain.
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:
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!

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.
If it does not, continue reading.
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.

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.
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?

- We’ve just published a new post about the best 50 gallon gas water heater on the market.
- A4.A high-pressure release valve is installed in the majority of the 40-gallon water tank.
- 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 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 What follows is a question about how long a 40 gallon hot water heater will take to empty. 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.
It usually takes about an hour or so for a 60-gallon unit to empty. How do you get the sediment out of a hot water heater that has built up? How to Flush Sediment from a Water Heater (with Pictures)
- 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.

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.
Examine the pressure-relief valve on a water heater before draining it. This is the device that prevents the tank from exploding due to excessive pressure. You must confirm that the valve is in perfect working order. The water heater’s electricity should be turned off.’ The unit should be turned off if it is powered by electricity (if so). The heater should be switched to “pilot” mode if it runs on gas.) After that, open the cold water supply line by pulling the lever on the valve. For the final step, place a bucket beneath the pressure-relief valve to contain the mess.
You should move to the next phase if you feel one of these symptoms, which indicates that the valve is functioning properly.

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 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, similar to tank capacity, will drain more water in a given amount of time.
- 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.
- Three, the amount of water pressure applied to the hose.
- 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.
- 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.
- 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.
- You should follow this guidance for the optimal implementation in the situation of a drain valve not being available.
- 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.
- As a result, the 60-gallon water heater will empty somewhat more quickly than the 40-gallon model in that situation.
- 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.
- For the most part, water heaters drain at a rate of between nine and seventeen gallons per minute (GPM).
- 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.
- 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 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.
If you have hard water, you may want to empty it more often as well.
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.

Why Is It Important to Flush and Drain Your Water Heater?
Different forms of sediment, such as limestone, chalk, and gypsum, get deposited in your water heater over time. Those are naturally occurring minerals that may be found in water and that, over time, accumulate in the bottom of your tank. Heat loss, longer heating periods, and leakages are all possible consequences of sediment building in a system. This is due to silt deposits accumulating on the burner plate at the bottom of your water heater, which prevents heat from flowing through the system.

Finding Information About Your Water Supply
To find out how often you should clean and empty your water heaters, see your water supply report from the previous year. On or before July 1, water companies send you an annual report that contains information on your water supply. This page contains information about where it originates from, what minerals it contains, and other pertinent information.
Keep in mind that if you have hard water (water with a high mineral content), your water heater should be emptied and cleansed more frequently than once a year. The report is usually included with water bills or made accessible for download on the internet.
What to Expect When You Flush and Drain a Water Heater

Water Heater Flush Cost
As you’ll see, a water heater flush is really inexpensive when you consider that it can be completed in a matter of minutes by following a few simple procedures.
How Frequently Should You Do a Hot Water Heater Flush?
If you consider how important your water heater is, you should not put off cleansing your system for an extended period of time. Every water heater has a varied lifespan, but making sure you clean out your water heater on a regular basis can help it last as long as it was designed to. A flushing of your heater should be done every couple years or so, on average. In order to guarantee the optimum performance from your unit, flushing it once a year is recommended, and the following instructions will demonstrate how simple it is to do.
Steps for Performing a Water Heater Cleanout/Flush
Your heater, like any other item in your home, will require some level of electrical power to operate properly. Depending on your unit, you may only need to complete one of these procedures during a water heater flush, or you may need to complete all of them. By turning off your gas, you can assure that the machine is not getting any gas and will not overheat or leak as a result. In most cases, turning off the electricity to your unit may be accomplished through your circuit breaker, which should include a switch labeled for the heater.
Keeping this step in mind will help to provide a safe working environment for whoever is responsible for finishing the flush.
Open a Hot Water Faucet
This is accomplished by tricking your system into believing it is required to be running, which requires you to open a hot water tap in your home. Despite the fact that water will flow out, it will not be heated at the time of the process. In addition, this procedure is critical because it prevents a vacuum from accumulating in the pipes, which might result in the formation of undesired air bubbles in your water system.
Turn Off the Cold Water Valve
Your water heater will have a supply valve that will connect to the unit and be used to feed cold water to the unit. You will want to turn off this valve while you are completing the flush. It should be positioned on or near your unit, and it will usually be towards the top of the unit’s interior. It will have the appearance of a typical faucet valve, with the possibility of being dyed blue to indicate cold water. It is important to turn this valve off during the flush process to avoid water running into the unit, which would make the whole procedure a lot messier.
Connect a Hose to the Heater
Find the location of your spigot as the next step. This will be located at the bottom of the unit and will seem to be a standard hose faucet in appearance. You may want to set a bucket below this before proceeding with the rest of the project because it may begin to drip as soon as the lid is removed. It is necessary to locate a garden hose that can be screwed onto this spigot since this is the most convenient method of draining the system. If your water heater is located higher up in your home, gravity should be able to facilitate the flow of water.
If the unit is located in your basement, a pump may be required to assist in the removal of the water from the unit. Make certain that the hose’s end is placed in some form of pail or containment area to prevent it from spilling everywhere.
Water Heater Flush for Sediment: Drain the Tank
It is at this point that you may begin draining the unit by turning the faucet to which the hose has been connected. It is possible to see the circumstances that your heater may be encountering when the water drains out of the tank during this period of time. If the water is largely clear and typical in appearance, it is likely that your water heater is in good working order. Water that is deeper in color and that contains silt, on the other hand, might be a much greater problem. The inside of the tank might be in far worse shape than you can remedy with a simple water heater flush for sediment if you are emptying the tank and a large amount of solid material is coming out of the tank.
This step will be skipped if you are flushing a tankless electric water heater, which is the most common scenario.
Flush the System
Now that the water has been removed from the system, you will begin the process of flushing the unit. Keep in mind that you already switched off the cold-water spigot. This is what you will be turning back on in order to allow the new water to clean out the system properly. It is recommended that you drain the old bucket and thoroughly inspect it for sediment before refilling it with the fresh cleansed water. Remove the tank’s fill valve and flush it for a few minutes until the water pouring out seems clean and typical.
Always remember to switch off the cold-water supply before unhooking the hose and removing the bucket from the sink.
Reactivate Power and Gas
Now that the flushing has been completed, it is time to clean up. The first step is to cut off the drain to which the hose was attached in order to prevent any water from escaping through it. Also, remember to turn off the hot water tap in your house that you opened at the beginning of this process as well. Replace the cold water supply valve and let the tank to re-fill with cold water. When your tank is full, you’ll want to open the pressure valve on the tank to allow the air to leave for the machine to function properly.
Finally, re-start the gas and water lines heading to the storage tank.
Conclusion
Clean-up has begun now that the flushing has been finished. In order to prevent water from escaping, the first step is to turn off the drain that the hose was attached to. Also, remember to turn off the hot water tap in your house that you opened at the beginning of this procedure. Replace the cold water supply valve and let the tank to re-fill with cold water again. When your tank is completely full, you will want to open the pressure valve to allow the air to leave for the machine to function properly.
Open the hot water faucet in your home once again to allow any trapped air out of the building. After that, re-start the gas and water lines that lead to the storage tank. To ensure that the water coming out of your residence is hot when needed, allow it to heat for around 30 minutes before testing.
