Use These Tips to Drain a Water Heater Properly
Most water heater maintenance instructions recommend that you drain a water heater every six to twelve months, depending on how much use it gets. The reason for this is that it will aid in the removal of any sediment or buildup that may have accumulated on the bottom of the water heater tank as a result of the presence of minerals and other particles in the water. As a result of the accumulation, the water heater will have to work harder to heat the water, consuming more energy and increasing its operating costs.
Before You Begin
According to the majority of water heater maintenance instructions, it is recommended that you drain your water heater once every 6 to 12 months. As a result of the presence of minerals and other particles in the water, it is advised that you do this to help remove any sediment or buildup that has accumulated on the bottom of your tank’s bottom. When this accumulation occurs, the water heater must work harder to heat the water, consuming more energy and increasing the overall cost of operating it.

Perform a Quick Flush
- Using a garden hose connected to the drain valve, attempt to clean the water heater tank a little bit while the water pressure is still on before shutting off the water supply. In order to accomplish this, first open the drain valve for a few seconds before closing it again. The pressure will blast away any silt that has become lodged in the valve, allowing the tank to empty more quickly. If a significant amount of sediment is expelled, you may need to repeat the process several times. Make certain that you’ve connected your garden hose to an outdoor place or into a bucket in order to collect the water and sediment that will be emitted from the faucet. The Spruce / Kevin Norris

Turn Off the Water Heater
- Turn off the gas to your water heater, or turn off the electricity if you have an electric water heater. Remove water by shutting off the valve on the cold-water pipe above the water heater or the main water supply valve to the home, whichever is most convenient. Test the hot water faucets around the home by turning them on and checking for water to ensure that the pressure has been released. Water may flood out at first, but if the water has been cut off properly, it should rapidly decrease to a trickle and then stop. It is important to leave a hot water faucet open in the sink closest to your hot water heater in order to relieve pressure in the entire system. The Spruce / Kevin Norris

Open the Drain Valve
- Open the drain valve while holding your garden hose in one hand. Normally, you may complete this task by hand, but you may need to employ your flat-head screwdriver in this instance. Once the valve is opened, water will begin to rush out of the drain, so make sure your hose is either connected to the outside or to a bucket to catch the water. You should switch off the drain valve as soon as the bucket is full so that you may empty it. Repeat the operation as many times as necessary to completely empty the tank. The Spruce / Kevin Norris

Flush the Tank With Water
- Open the drain valve while holding your garden hose in your hand. The majority of the time, you can complete this task by hand, but you may need to employ your flat-head screwdriver in this situation. After you have turned the valve to the open position, water will begin to rush out of the drain, so make sure your hose is either connected to the outside or to a bucket nearby. You should switch off the drain valve as soon as the bucket is completely full so that you may empty it. The operation should be repeated as many times as necessary to completely empty the tank. Kevin Norris’s novel The Spruce
Refill the Water Heater
- Attach your garden hose to the drain valve and turn it on. Normally, you may complete this task by hand, but you may need to use your flat-head screwdriver in this instance. Once the valve is opened, water will begin to rush out of the drain, so make sure your hose is either connected to the outside or to a pail to catch it. As the bucket fills, close the drain valve to allow you to empty it. Repeat the procedure as many times as necessary to completely empty the tank. The Spruce / Kevin Norris

Relight the Water Heater
- Re-ignite the water heater’s pilot light, or if it’s an electric heater, re-energize the circuit breaker. You should be able to use hot water after an hour or so. The Spruce / Kevin Norris

Check the Drain Valve
- Check for leaks at the spout of your water heater to see if the drain on the heater has completely closed. If the outlet does not completely close, you can stop the leak by placing a threaded hose cap over the hose thread of the outlet. Alternatively, you can replace the valve entirely.

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.
Photograph courtesy of shutterstock.com. For the first time since it was installed in 1989.24 years ago.I just finished draining my water heater. I stopped after approximately five minutes since the water came out quite pure, with no signs of silt. So, my heater has no sediment, does this imply that it is clean? Whatever sort of storage tank water heater you own, draining your water heater once a year is a good idea. Over time, sediment accumulates within the appliance, reducing its energy efficiency and causing blockages in other fixtures throughout the house, including the dishwasher.
A water heater must be thoroughly drained in order to eliminate sediment, which means it must be drained for an extended period of time (not just five minutes).
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.

Frozen Hose Bib: How to ThawPrevent Major Water Damage
The capacity of hot water tanks is meant to last for many years, but cleaning them should be included in your normal home maintenance program. Following our step-by-step directions outlined below, this is an easy DIY project that you can complete on your own.
Why should I flush my water tank?
The majority of hot water tanks feature a large holding tank, which guarantees that there is always sufficient of hot water available when it is needed. Nonetheless, because the water is left to stay in the tank on a continuous basis for an extended period of time, naturally occurring minerals in the water, as well as sand and grit discharged from municipal water pipes, can accumulate in the tank’s bottom. The accumulation of silt in your hot water tank may make it more difficult for it to perform its function.
This increases the likelihood of your water heater breaking sooner than it should. Hot water tanks should have a life lifetime of at least 10-12 years, however failing to remove the sediment from the tank on a regular basis can dramatically shorten that life term.
What about my gas hot water tank?
In addition, sediment can reduce the effectiveness of the burner in a gas water heater. Have you ever experienced cracking and popping noises when your furnace was heating up? This is due to the silt that has accumulated in your tank. Sediment builds up in a gas hot water tank, forming a thick, crusty layer on the surface. This reduces the amount of heat that is transferred from the burner to the water in the tank. This is a waste of energy and, more importantly, of your money! In the long run, this can create corrosion in the tank, which may produce a major problem if your tank begins to leak all over your floor.
This will guarantee that your water heater performs at its best.
Can sediment affect my plumbing pipes or water?
Fortunately, the quick answer is “yes!” The sediment or crusty stuff that collects at the bottom of your tank has the potential to break loose and become caught in the pipes that distribute water throughout your home. This might cause the flow of water via your pipes and faucets to become more difficult to control. It also has the potential to clog the drain valve on your hot water tank, making it hard to drain the tank without a major plumbing repair job.
An important word of advice:
If you haven’t cleansed your hot water tank in a number of years, it may be in your best interests to hire a Licensed Plumber to take care of the job on your behalf. You run the danger of causing leaks to be activated. It’s conceivable that the silt that has been accumulating in the tank for years has developed fractures in the bottom of the vessel. The existing sediment is clogging those cracks, however draining and flushing the hot water tank may be able to remove the sediment that is “sealing” the leaks and allowing them to reopen.
The fact that you hired a Licensed Plumber to complete the operation ensures that if it does leak, you’ll be prepared to deal with it immediately.
Speaking from experience.
The reason I warn you with the word of advise above is that we had exactly that scenario occur with a client of ours and we wanted to share our experience with you. Approximately 7 years ago, I published a simple advice to draining your hot water tank in a newsletter that I had written. After eight years in his house, my client realized that he had never drained the tank and decided that it would be a good idea to do so now that the weather was getting warmer. He diligently followed all of my directions before calling me in a panic because there was water coming out into his basement floor and he needed me to come immediately.
He, on the other hand, had not anticipated such a problem as a result of following my detailed directions.
It was clear that they had been there for a long time, and the sediment itself was preventing the leak from occurring again.
Our customer ended up needing to purchase a new hot water tank, but he ended up saving a significant amount of money over the long run since his new tank was far more energy efficient. Our client now flushes his hot water tank once every six months as a preventative measure.
One important first step
The first step is to identify where the drain valve is located on your tank. It has the appearance of a little outside faucet. Before draining your hot water tank, we highly advise that you cut off the gas or electricity to the tank and let the water drop to room temperature before draining it. It will take several hours to complete this task. This is not required in order to drain your tank, however it is recommended as a safety measure. If you do not want to wait the appropriate amount of time for all of the water in your water heater to cool, just keep in mind that the water that comes out of the drain valve will be extremely hot when it does.
Steps to Draining Your Hot Water Tank
- Turn off the gas or electrical power to your hot water tank if it is connected. The “pilot” setting on a gas water heater is what you’ll want to use. If the water heater is electric, turn off the breaker or unplug the fuse located at the electrical panel
- Turn off the cold water supply valve located at the top of the water heater
- And turn off the gas supply valve located at the water heater. When you touch this pipe, it should be ice cold. If the valve feels warm to the touch, you’ve got the incorrect valve. Locate the tank drain valve, which should be towards the bottom of the tank, and connect a regular garden hose to the drain valve. Keep in mind that certain models may have a cover over the valve opening
- The other end of the hose should be placed in a floor drain or on a driveway where it may safely drain. Buckets can be used if required, but take care not to be burnt by the hot water while you’re doing your task. To prevent this from happening, make sure the hose’s end is lower than the water tank’s valve. Locate the hottest water tap that is closest to the water heater, preferably on the second or third story above. Opening the drain valve and allowing the water to flow from the tank can relieve pressure in the system, similar to withdrawing your finger from the top of a drinking straw loaded with liquid
- Close the drain valve and let the water to drain from the tank. Once again, if you haven’t allowed the water to cool before using it, proceed with caution. Once all of the water has been emptied from the tank, switch on the cold water supply to the tank for a limited period of time. This will help to stir up any silt that has accumulated. It is necessary to repeat this procedure until the water flows clean
- Disconnect the drain line and switch on the cold water supply valve after closing the drain valve. The tank will begin to fill as soon as possible. Return to the hot water faucet that was previously opened. Once cold water begins to flow from the faucet, cut off the water supply. Return the gas valve to the on position from the pilot position, or reconnect the power to the tank. It is important to double-check the valve opening once it has been closed to ensure there are no water leaks.
What if my tank won’t drain?
Your hot water tank’s gas or electricity supply should be turned off first. The “pilot” setting on a gas water heater is what you’ll need to use. Shut off the breaker or remove the fuse at the electrical panel if it’s an electric water heater; close the cold water supply valve located at the top of the water heater if it’s a gas water heater To the touch, this pipe should be very cold. If the valve feels warm to the touch, you have the wrong one. Locate the tank drain valve, which should be towards the bottom of the tank, and connect a regular garden hose to it.
- Buckets can be used if required, but take care not to be burned by the hot water while you work to avoid getting scorched.
- Opening the drain valve and allowing the water to flow from the tank can relieve pressure in the system, similar to withdrawing your finger from the top of a drinking straw full with liquid; close the drain valve and let the water to drain from the tank.
- After all of the water has been emptied from the tank, switch on the cold water supply to the tank for a brief period of time.
- Continue in this manner until the water runs clean, then stop.
- Beginning with the next refill, the tank will fill up.
- Once cold water begins to flow from the faucet, cut off the water supply immediately.
- As soon as the valve is closed, double-check to see if any water is leaking out of the aperture.
To sum things up.
Despite the fact that it is one of the most often used items in your home, the hot water tank is also one of the most ignored.
If you follow the methods outlined above, maintaining your hot water tank will be a simple chore. If you prefer that our Licensed Plumbers handle the maintenance on your hot water tank, please contact us at 905-259-3344 to make arrangements.

- It is necessary to flush your water heater tank twice a year in order to remove mineral silt and scale accumulation. With improved efficiency and longevity, your water heater will perform better. This professional guidance demonstrates how to flush and drain a water heater through the use of videos, graphics, and simple text. The following are the reasons why flushing or partially emptying a water heater is necessary. Firstly, it helps to avoid the accumulation of mineral deposits within the water heater. Mineral deposits build up in a water heater tank over time, resulting in silt and scale build-ups. A very thick, crusty coating can form at the base of a gas water heater, and the heating components of an electric water heater can be completely covered by these deposit buildups as well. In addition to losing energy and money, this coating reduces heat transfer from the burner or heating sources to the water in the tank. It eventually results in rusting as well. Scale and mineral deposits can eventually break loose, causing the flow of hot water via pipes and faucets to be slowed significantly. They can also clog the drain or flush valve on a water heater tank, which can cause it to overflow. ADVICE FROM EXPERTS What many people are unaware of, however, is the following fact: Some plumbers advise against flushing your water heater if it hasn’t been flushed in years since doing so may cause leaks to appear. As an example of a theory: Tiny fractures in the base may have filled with sediment, which helps to prevent leaks, especially in a gas water heater where the flame has been roasting the steel bottom for a long time. Because the sediment is being flushed out, it’s possible that part of the leak prevention will be compromised. Consider consulting with a few of plumbers in your region if your water heater hasn’t been cleansed in years and might benefit from their advice.

- To avoid scorching, exercise extreme caution.
- 5Depress the drain valve on the water heater.
Once this is done, close both the drain valve and the PT valve.
In the event that you are totally draining the water heater, leave the drain valve open until the tank is completely empty.
7Refill the water heater with fresh water.
Return the water supply valve to its original position to re-fill the tank.
Then, reopen the hot water faucet to allow any remaining air to escape from the tank and pipes.
Allow the water to clear for a few minutes before turning off the faucet. 8Restart the water heater if necessary. If you have a gas water heater, relight the pilot light, or switch on the electric circuit if you have an electric water heater.
Water Heater Won’t Drain
If your water heater is draining slowly or not at all when you open the drain valve, you should try opening the pressure-relief valve to see if it helps (see the illustration at the top of this page). This has the potential to dislodge the vacuum that is keeping the water from leaving. In most cases, if the water heater won’t drain or drains slowly, the problem is most likely due to an excessive amount of sediment building up in the water heater. The drain valve of a water heater can become clogged with sediment.
First Steps in Breaking a Drain Valve Clog
It may be necessary to open the pressure-relief valve if your water heater is not draining properly or at all when you open the drain valve (see the illustration at the top of this page). This has the potential to dislodge the vacuum that is keeping the water trapped. In most cases, if the water heater won’t drain or drains slowly, the problem is most likely caused by a buildup of silt in the water heater’s tank. In some cases, sediment can jam the drain valve on a tank-type water heater. You may drain a blocked water heater through the drain valve by following the methods outlined below.
How to Back-Flush a Water Heater

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.
Disconnect the tank’s water supply with a hose until the water begins to flow clean of sediments.
In addition, if you’ve opened the water heater’s pressure-release valve or any hot water taps, make sure you close those as well.

Know When to Drain the Tank
Natural minerals found in your home’s water supply might accumulate at the bottom of your water heater tank over time, causing it to malfunction. Because that sediment can impair the effectiveness of the heater, limit its life, and even cause blockages, keeping it cleansed is a good idea. Experts recommend that you wipe away the sediment around once a year, according to the experts. Part of determining when to do it will depend on how hard your water is and whether or not you’re linked to a municipal water supply where sand and grit may find their way into the water supply.
How to Drain a Water Heater
The first step in this project is to make sure that your water heater is turned off before you begin. With a gas water heater, you may accomplish this by setting the knob to “pilot.” The circuit breaker that controls your electric heater must be found and turned off in order to prevent damage to the heater from occurring. Typically, the water heater is protected by a separate circuit breaker. It will be necessary to turn off the cold water that feeds into the tank as well, which can be accomplished by twisting a knob located at the top of the tank in the opposite direction.
Step 2: Run the Drain Line to a Good Draining Location
In order for the water within the tank to be able to depart, you must first provide a passage for it. As long as your water heater is elevated or located on a higher floor of your home, the process of draining the water heater can be as simple as connecting the heater to a safe draining position outside your home. If the water heater is located below grade, such as in a basement, you have two options to consider. Use a bucket to collect the water, or you may purchase a pump and attach a hose line to pump the water up and out of the hole.
Step 3: Check Your Pressure Relief Valve
When it is not a “must-do” step in the process, inspecting your pressure relief valve while cleansing your water heater is always a good idea regardless of whether it is necessary. It will aid in the release of pressure in the tank, preventing the formation of a vacuum. You just switch the latch on a valve located on the cold water pipe that supplies the tank in order to do this task. The valve is in excellent operating condition when you hear a hiss and see water spurting out – it’s a good idea to do this with a bucket or cloth nearby, by the way — which indicates that the valve is in good working order.
You’ll need to contact a plumber in order to have the valve evaluated and maybe replaced if this is the case.
Step 4: Open the Hot Water Faucets in Your Home
Start all of your hot water faucets in your house at the same time to relieve even more pressure in the tank and aid in its emptying. If you prefer, you can simply turn on the hot water tap that is closest to the tank. Additional Related Articles:

- Whether a tankless water heater is worth the investment.
Step 5: Open Your Drain Valve
Prepare your bucket or pump system, and then release the drain valve located towards the bottom of the tank to allow the water to drain. A built-in knob is normally available for this valve, however it is occasionally necessary to put a flat-head screwdriver into a slot and turn it counterclockwise to operate it properly. It is at this moment that water will begin to pour out of the tank in large quantities, so be prepared to collect or redirect it as soon as possible. In order to empty your bucket, you can shut off the valve whatever many times you need.
Step 6: Flush the Tank
However, even though much of the sediment will be removed simply by draining the tank, it’s always a good idea to check that your water heater is completely clear of sediment by flushing it with cold water. To do so, just turn the cold water knob at the top of the tank back on and let it run until the water drains completely out of the hose linked to the drain valve, which should take around 15 minutes. If the water flow stops at any time throughout the draining process, you’ll want to remove the hose and use a tiny screwdriver or awl to scrape away any debris that may have accumulated in the output.
Step 7: Refill the Tank and Turn It Back On
Remove the drain knob from the water heater once it has been completely cleansed and the output is flowing freely again. Ensure that you close your pressure release valve if you had previously opened it. Then, reconnect the cold water supply line at the top of the tank by turning it back on. Make your way to the hot water spigots that you previously unlocked and wait for the water to start flowing through them. When this occurs, you will be able to turn them off. Depending on the type of water heater you have, you will need to either turn the electricity back on or the gas back on.

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