How To Empty A Hot Water Heater

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

Before you begin, make sure you understand where the main water shutdown valve is situated in your home. While you won’t necessarily need it during this procedure, it’s always a good idea to be familiar with this valve whenever you’re dealing with any type of plumbing fixtures in your house in case something goes wrong and you need to shut off all water coming through your pipes.

Safety Considerations

When doing this procedure, you will be working with water that can be quite hot. It is possible that you will need to switch off your hot water heater many hours before you begin in order to allow the water in the tank to calm down before you begin. If you are unable to do so, use heavy-duty rubber work gloves to protect your hands from any splashes and safety glasses to protect your eyes from any hot water droplets that may fall over them.

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
  • The Spruce / Kevin Norris

Flush the Tank With Water

  • Once the tank has been completely drained, you may flush it with a few gallons at a time by turning on the water for a few seconds and then allowing it to drain out again until it is completely empty. When the outflow is clean, you’ll know that you’ve successfully eliminated the sediment and may proceed to the following phase in the process. The Spruce / Kevin Norris
  • The Spruce / Kevin Norris

Refill the Water Heater

  • Close the drain valve and remove the garden hose from the system. Make certain that all but one of your home’s hot water faucets are turned off (the one in the bathtub closest to the water heater is best). You may now re-start the water heater by turning the water back on. After that, keep an eye on the faucet you left open and, as soon as you notice that you are receiving nothing but water out of it, turn it off. The Spruce / Kevin Norris
  • 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
  • The Spruce / Kevin Norris

Check the Drain Valve

  1. 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.

Why Drain Your Water Heater Tank?

On average, a tank-style water heater sees a large amount of water pass through its tank over the course of a year. While softened water is used in many houses today, certain minerals and sediment are still carried into the water heater — and if you have hard water, your water heater is more adversely affected by higher concentrations of these pollutants. During the storage of water in the tank, silt and minerals fall to the bottom of the tank where they gather. Water passing through them leads them to accumulate over the course of a year, causing troubles for your tank.

  • The water that passes through a tank style water heater over the course of a year is a significant amount. Even in houses with softened water, minerals and silt are carried into the water heater by the water – and if you have hard water, your water heater is subjected to higher concentrations of these pollutants. During the storage of water in the tank, silt and minerals fall to the bottom of the tank where they accumulate. They grow and grow over the course of a year as water runs through them, causing troubles for your storage tank. It is possible to have numerous problems caused by sediment accumulation.

When Not to Drain Your Water Heater Tank

When sediment accumulates in the water heater tank, hot spots along the bottom metal are frequently created, causing the metal to corrode and eventually fail completely.

If your tank is full of sediment, it’s possible that the sediment has actually closed these little leaks over the course of several years. If you drain the water heater and remove the sediment all at once, you will almost certainly end up with a leaking water heater.

Frozen Hose Bib: How to ThawPrevent Major Water Damage

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. It is important to note that having a lengthy, hot shower is a good approach for expediting this stage of the draining process!

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.

The water heater drain valve should be opened after you have opened all of the hot water taps in your home. The moment has come to turn on your pump, if you have chosen to use one.) Remove all of the water from the tank before turning on the water valve (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 water flow by doing the following: Remove the drain valve, in other words, to allow the silt to escape through a bigger hole.

How to Drain Your Hot Water Tank (And Why You Should!) — Multi Trade Building Services

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.

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.

Both gas and electric water heaters should be cleaned of sediment every 6 months to once a year, depending on your water supply and the mineral content. 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.

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

  1. 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
  2. Turn off the cold water supply valve located at the top of the water heater
  3. 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
  4. 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
  5. 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
  6. 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?

If your hot water tank is draining slowly or not at all, open the temperature and pressure relief (TPR) valve on the hot water tank to see if it helps. In the hot water tank, it’s at the top where you’ll find it. A pipe goes from the top of the tank to the bottom of the tank, and it’s normally operated by a lever that may be raised or lowered as needed. Opening the TPR valve may allow water to drain from the tank if there is a possible vacuum inside the tank that has been preventing it from doing so.

The most prudent course of action is to contact a Licensed Plumber in this situation.

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.

How to Flush Your Hot Water Heater

If you’re busy with home tasks, it’s easy to ignore the importance of flushing your hot water heater.

How to Flush Your Hot Water Heater

Hot water heaters are available in two different configurations: gas and electric. Due to the fact that I have a gas hot water heater, following instructions will be specific to flushing a gas hot water heater. While there are some similarities between gas and electric, the most significant distinction is that with gas, you will be shutting off the gas to your appliance; with electric, you will be turning off the power to your appliance. 1. Turn the Thermostat on your hot water heater to the “Off” position.

  1. In most cases, the thermostat for a gas hot water heater may be found in the bottom of the tank.
  2. If you switch off your hot water heater and it’s an older type, you’ll have to re-light the pilot light, which might be a hassle.
  3. 2.
  4. If you have a gas hot water heater, locate the gas pipe that runs from the tank to your thermostat and pilot light and switch the valve to the “off” setting.
  5. 3.

  7. Turn it all the way off.

Fill a sink or tub with hot water by turning on the faucet.

As a result, you will be less likely to have a vacuum build in the pipes while draining the hot water tank.

Connect the garden hose to the drain spigot on the wall.

Depending on whether or not your hot water heater is located in the basement, you may require a portable pump in order to pump water from the basement to the first floor of your home.

Turn on the spigot and drain the water.

If your tank is clogged with silt, you may need to thoroughly drain it.

I decided to drain it anyhow.

Flush your hot water tankTo flush your hot water tank, just switch on the cold water tap that leads into your hot water tank.

This might take some time.

Here’s a photo of the water that was flowing out of my tank when I first started flushing the toilet: As you can see, there was still some silt (which can be seen at the bottom) pouring out of the hole.

Flushing should continue until there is very little or no sediment left in your water. Turn off the cold water faucet that feeds into your hot water tank and leave it shut.

Finishing Things Up

Following your satisfaction with the purity of your water, it’s time to return everything to their original state.

  • Disconnect the drainage spigot and the hose from the drain
  • Turn off the water supply to your sink or tub that you had switched on at the start of the process. To begin, turn on the cold water tap that feeds your hot water heater. To get the air out of the system, turn on the hot water faucet in a sink or bathtub for a few minutes. At this point, you should be able to get cold water out of the faucet. To turn it off, press the button. Restart your hot water heater if you have accidentally turned off the gas supply. If you have accidentally switched off your hot water heater’s thermostat, re-light the pilot light (it’s simple — I may write an article on it in the future), and then turn the thermostat back on. For electric water heaters, locate the breaker switch on your electrical panel that supplies electricity to your hot water heater and turn it off. Allow around 20 minutes for the water to warm up. Start by turning on one of your house’s hot water spigots to confirm that hot water is flowing out

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 Using a hose, connect it to the tank drain valve, which is located in the bottom of the water heater, and direct it to a drain, the outdoors, or a large bucket.
  • Fill the tank with water by connecting a hose to the water heater’s drain valve.
  • As the water drains, this prevents a vacuum from building in the system.
  • 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.

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.

How to Flush Your Water Heater

Water heaters can lose their efficiency over time, resulting in greater heating costs as well as increased water bill costs. The silt that has accumulated in the tank is the source of their decreased efficiency since it is obstructing heat transfer and absorbing some heat at the same time. It is also possible that this sediment will cause harm to your water heater as well as obstructions in your water lines. An easy solution to this problem is to do a simple flush of your water heater. Most experts advocate having this done once a year at the very least.

Check with your manufacturer’s guarantee about maintenance to ensure that completing the maintenance yourself will not violate your warranty.

Steps to flush the water heater

Close or reduce the heater’s heating system or gas supply to prevent the water heater from going on and heating an empty tank of water. Setting your gas water heater’s thermostat to “off,” “pilot,” or “vacation mode” is one option; but, if you have an older system, it may be necessary to cut off the gas to the water heater as well as turn off the water heater itself. In certain older gas water heaters, if the gas has been turned off, you may need to relight the pilot light, and you should be familiar with how to do so and where it is situated before doing so.

  • If there isn’t a switch or unplug option, you may have to turn it off with a circuit breaker if there isn’t another means to stop the flow of energy to the water heater.
  • The main water valve to the house in some residences; in others, a shutdown valve near the water heater may be used instead.
  • Connect a garden hose to the tank’s drain spigot, which is located towards the bottom of the tank.
  • Place the other end of the hose in a location that is capable of handling the volume of water and the heat generated by the currently hot water in the water heater tank, if necessary.
  • When you have determined that the water temperature is cold enough, repeat the previous procedure and switch off the water supply to the heater to complete the process.
  • Allowing the tank to empty through the hose is accomplished by opening the drain valve.

If you don’t hear any water running and you don’t see any water draining from the end of the hose, you may have something blocking the air from flowing, such as a backflow preventer, or sediment has clogged the drain, and you will need to open the pressure release valve to allow air into the system to work properly.

Most Check the hose to make sure there isn’t any leakage along the way, and that the other end is still draining at the location you’ve picked, and that the water draining isn’t going to overflow the draining area after you’re finished.

At the end of the draining process, you want the water to be completely clear or mainly clear.

It may be necessary to turn on the water for approximately 15 seconds, then turn off the water and wait for a few minutes before repeating the process a few times to entirely remove any silt that has become lodged on the interior of the drain.

Observe the water draining to ensure that all sediment has been removed and that the water being drained is free of obstructions. When you have done flushing the system, turn off the water supply to the tank.

Now that the system is cleaned out, it’s time to put everything back:

  • Close the drain valve and take the hose out of the system. Re-open and close the pressure valve (if you already opened it
  • If not, double-check that it is still closed)
  • Restart the water heater by turning the water back on. Open all of the hot water taps in the house to confirm that the water is flowing and that there is no trapped air. The water may appear cloudy at first, but wait until the silt has disappeared. The faucet should be turned off after the water is clear. Turn on the heating source, which may entail re-igniting the pilot light if the water heater is a gas model and the pilot has gone out. Make careful you only turn it on when the tank is completely full. It is dangerous to turn on an electric water heater while the tank is not completely filled because the heating element will burn out

Removing the hose and closing the drain valve Ensure that you have closed the pressure valve (if you have already done so, double-check that it is closed). Replacing the water heater’s supply with clean water Ensure that all of the hot water taps in the house are operational and that there is no trapped air. If you notice sediment coming from the faucets, simply wait until the water becomes clear. The faucet should be shut off after the water is clear. If you have a gas water heater that has blown out the pilot light, you will need to re-ignite the pilot light to get it going again.

Using an electric water heater without having a full tank will result in the heating element being destroyed.

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.

After you’ve switched off the water heater, you’ll want to wait a few hours for the water inside to cool down before continuing.

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

In order for the water within the tank to be able to escape, 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 it to a safe draining position outside. It is possible to use two different options if the water heater is below grade, such as in a basement. 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 house.

Step 4: Open the Hot Water Faucets in Your Home

After that, you’ll need to provide a pathway for the water to depart the tank. 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 it to a safe draining position outdoors. If your water heater is located below grade, such as in a basement, you have two options: You may either purchase a pump and link a hose line to the pump to pump the water up and out, or you can use a bucket to do it yourself.

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.

You should switch off the cold water faucet and seek expert assistance if you are unable to see or clear the sediment.

Step 7: Refill the Tank and Turn It Back On

While most of the sediment will be removed simply by draining the tank, it’s always a good idea to double-check that your water heater is completely clear of sediment by flushing it with cool water. This may be accomplished by simply turning on the cold water knob at the top of the tank once again and letting it run until the water drains completely out of the hose connected to the drain valve. You should remove the hose if the water flow stops at any stage throughout the draining process and use a tiny screwdriver or awl to clean away any debris that may have accumulated in the outlet.
