How to Flush a Water Heater

  • Article to be downloaded article to be downloaded According on the type and supply of water, water heaters should be cleansed every one to three years on average.
  • This aids in the prevention of the accumulation of mineral deposits.
  • Your water heater will work more effectively as a result, which will often result in a longer service life for the heater.
  • To flush your water heater, follow the instructions on this page.
  1. 1 Locate the breaker/fuse box if the heater is powered by electricity, or the thermostat if the heater is powered by gas. First and foremost, you will need to locate and switch off the primary power supply for your water heater before you can begin emptying it. In most cases, the breaker box, also known as the fuse box, is a tiny, grey power panel (about the size of a shoebox) with a sliding door. In most cases, it is fastened to a wall by screws. In some homes, the thermostat for the gas heater is situated in the garage, while in others, it may be found on the exterior of the house
  2. the thermostat for the gas heater is often a red knob positioned on the outside of the heater near where the gas line enters the unit. There should be three settings on the knob: ″Pilot,″ ″On,″ and ″Off.″
  • 2 Disable the circuit or fuse that supplies electricity to the electrical water heater, or set the gas water heater’s thermostat to ″Pilot″ position. According to the circuit or fuse you block, either the water heater or the entire house will be without electricity as a result. There should be modest on/off switches visible. These are referred to as ″branch circuit breakers,″ and they are responsible for providing protection against electrical overload to the many circuits that power your home. If you know which branch circuit breaker is responsible for powering your water heater, you can turn off that specific switch.
  • If you are unsure of which specific circuit breaker is providing electricity to your heater, look for a bigger switch labeled ″Main″ above the branch circuit breakers to find.
  • The primary circuit breaker should have a greater amperage rating, such as 100, 150, or 200 amps, to protect the system.
  • Smaller numbers will be assigned to the branch circuit breakers, ranging from 10-60 amps.
  • Open your fuse box and you will discover round, glass-topped forms or tiny tubes with metal ends
  • if you open the box and find round, glass-topped shapes or small tubes with metal ends, you have a fuse box rather than a circuit breaker box. In this situation, you will need to unscrew and remove the fuse that is supplying electricity to your water heating system (similar to turning off the branch circuit breaker). Identify a huge rectangular box with a handle/lever at the top of the panel if you are unclear about which fuse to remove. Take a firm grip on the handle and pull it straight out, but be careful since the metal pieces may be hot. The electricity to your entire home has been turned off at this point.
  • Promotional material
  • 3 The cold water supply can be turned off by twisting the water shut-off valve counterclockwise. This valve should be situated at or near the cold water inflow pipe, which should be located towards the top of the tank. Ball valves and gate valves are the two types of valves that are often used. A ball valve can be closed and opened with a single 90-degree turn, whereas a gate valve requires many revolutions.
  • Some gate valves have a ″stop″ before they may be fully closed or opened, so be sure you turn the valve past that stop before closing or opening it completely.
  • It is permissible to leave the gas and propane supply valves for non-electric heaters open.
  • Make a note of the temperature setting on your natural gas or propane (LP) water heater, and then change the thermostat, which is the huge red dial on the front of the control, to the lowest setting, often known as ″Pilot.″
  • You should turn off the heat ahead of time and allow the water to cool overnight before emptying it if you intend to utilize the water for other reasons.

4 Turn on the hot water tap in your sink or tub to get started. This will prevent a vacuum from forming in the lines, which would otherwise keep the water trapped inside. As an illustration, consider the case of a straw that has been partially covered to retain water.

  • 5 Connect a garden hose to the drain cock, also known as a valve, which is positioned at the base of the heater. It is generally in the shape of a standard garden hose fitting, such as a garden faucet, or a circular dial with a threaded hole in the center. You may need to remove a cover to access the drain cock. If you don’t have a garden hose, you can use a bucket to collect the water and physically dump it somewhere safe. Don’t overfill the bucket since the hot water will weaken less expensive plastic buckets or even burn you if you overfill it.
  • 6 Extend the garden hose to a location where the water from the heater may be discharged without danger. Either connect your hose to an exterior drain or to the driveway of your house. It is possible to drain the water into buckets and use the water for other uses once it has been allowed to cool overnight. Because of the presence of sediment, it should not be used for fragile plants or to wash your car. If you are draining hot water, you should also be cautious about the materials you use. High temperatures can cause low-quality hoses and buckets to weaken, resulting in leaks. Drain directly into a suitable basement drain or sump hole to make the operation as simple as possible.
  • To avoid scorching water from blasting and spraying out of a drain cock and hose connection in the event of a pressure leak, especially if the water heater serves the second floor or is located in the basement, cover them with a cloth or rag before turning on your faucet.
  • Drain the heater by opening the flow cock to enable the water to drain from the heater. Take into consideration opening the pressure-relief valve, which is often located on the unit’s top, to allow water to flow freely. The pressure-relief valve, on the other hand, should not be opened without first putting a bucket under the discharge pipe. Opening it may result in water draining onto the floor unless something is placed beneath the discharge pipe to catch the water as it drains. The pressure relief valve is often a lever that must be moved to the ″up″ position in order to be opened.
  • Make certain that the water flows at a pace that can be regulated wherever the water is draining to
  • Keep in mind that if you don’t allow the water to cool down before using it, it will be quite hot as it exits the tank.
  • Be aware that if the drain cock is made of plastic and the heater is many years old, it may be difficult to open and, if forced, may shatter.
  • 8 After a few minutes of flushing, fill a ″test″ bucket with the water that is remaining in the toilet. After allowing the water in the bucket to remain undisturbed for a minute, check to see if it is clear or if any sand-like material has settled to the bottom of the bucket. The tank should be drained until the water is clear, even if it seems to be foggy or there is sand-like material on the bottom of the bucket (free of sediment or discoloration). If the tank is completely empty but you believe sediment is still there, switch on the cold-water supply to allow additional water to enter the system. Fill the tank partly with water and then empty it completely. Continue to follow this procedure until the discharge is clear.
  • If the water is clean and there is no evidence of silt, you may go to the following stage
  • otherwise, stop.

1 Disconnect the garden hose from the drain cock and close the drain cock. If the pressure-relief valve has been opened, it must be closed. In addition, make sure you shut off the hot water tap in your sink or bathtub.

  • 2 Reconnect the water supply and let the tank to fill.
  • When the tank is completely full and the pressure has returned to normal, slowly reopen the pressure-relief valve to allow the extra air to be released.
  • The water heater will not ″ping″ as cold water re-enters the system during regular operation as a result of this.
  • Close the pressure-relief valve once again once all of the compressed air has been exhausted.

3 Close the drain on the water heater. To drain air from the bathroom, turn on the hot water faucet. Do not switch on the electricity just yet. You run the risk of damaging the heating element if you switch on the electricity without filling the tank. Start by turning on the hot water tap in the bathtub or washbasin and waiting for a steady stream of water to come out.

  • Reconnect the water supply and wait until the hot water line begins to run consistently after it has been turned back on. It is safe to turn on the circuit breaker or fuse box after the hot water tap has been flowing at maximum volume for a while.
  • 5 Turn off the water supply to the tub. Once you’ve waited around 20 minutes, check for hot water in the bathtub. To evaluate whether or not the water heater is operational, pay close attention to its sound.
  • Question Add a new question Question Is it ever necessary to use any additives, such as distilled vinegar, during the flushing and draining process? However, this is a professional-level work, and the type of acid needed will depend on the design of the heater.
  • Question Would it be permissible for me to switch off the cold water valve at the tank and take a shower in order to drain a little amount of hot water from the tank before connecting the hose to the drain valve? I really don’t want to waste all that hot water by flushing it down the toilet! That is not going to work. It will not be possible to use hot water if you close the cold water valve at the top of the faucet. Turning off the heating (gas or electric) and taking a shower is the best option. As the hot water is used up and replaced by cold water, the water will gradually get colder.
  • Concerning the Question What should I do if the water is hot when I turn it on but becomes chilly after a few minutes? There are several possibilities for what it may be. It is necessary to replace at least one of the components 90% of the time (normally the lower one). Additionally, the thermostat, dip tube, sediment, and other components are included.
  • More information can be found in the following answers: Advertisement When a pressure relief valve is opened, it is possible that it may be damaged and will need to be replaced. In order to avoid harming this safety component, open the highest faucet/sink on the home to bleed air out of the heater and lines before re-connecting the water supply lines.
  • The frequency at which heaters are flushed varies. If yours is more than a few years old or if you have recently moved into a new home, it should be flushed. How much sediment you detect will assist you decide how frequently it is necessary to cleanse that heater.
  • If the heater is powered by gas, do not turn off the gas supply to the heater.
  • Draining your water heater should be done using a garden hose.
  • If your home has a salt-based water softener, flush it once a year or every six months.
  • Be sure to cut off the power at the circuit box before emptying an electric appliance.
  • If you want to recycle water, make sure to prepare ahead of time.
  • If you want to avoid sediment accumulation, consider installing a whole-house filtration system. Also, remember to remove your aerators from your faucets while your tank is clean and full and to run a little clean water through each before reinstalling.
  • Thank you for submitting a suggestion for consideration! Advertisement Be cautious, since the water might be quite hot.
  • Do not turn on the water without entirely filling the reservoir. This will result in damage to the heating element.
  • You must take care not to break the drain cock.
  • Performing regular flushing will help to maintain your heater clear of dirt, but most plumbers advise that if the valve hasn’t been opened in more than five years, it’s better not to try to move the handle since the valve may fail.
  • You should seek the services of a qualified plumber if you do not feel comfortable performing this task yourself.
  • Do not turn off the gas or the pilot light on the water heater
  • instead, turn it to the lowest possible setting. You will not have to go through the relighting steps
  • instead, you will only need to crank up the gas control valve.

How To Clean A Water Heater The Simple Way

If you maintain your water heater properly, there is no reason why it shouldn’t survive for more than a decade or more. Knowing how to clean a water heater is one of the most important skills to have in order to do this. Our goal with this essay is to provide a comprehensive walkthrough of the process of cleaning your water heater, regardless of its make or model.

How To Clean Your Water Heater: The Basics

Why Should You Do It?

  • If you’ve read our article on drinking tap water in Phoenix, you’ll be aware that the water that arrives at your house in Arizona (or any other state in the United States, for that matter) includes silt, minerals, and chemicals.
  • In the course of time, these impurities might accumulate in your water heater, causing it to operate inefficiently.
  • Inefficiencies such as inconsistent heating, an element that fails to stay lighted, and a blocked drain valve are all examples of inefficiencies.
  • All of these will result in bills that are greater than planned.
  • In severe circumstances, the sediment accumulation can get so extensive that it causes leaks in your water heater’s internal components.
  • The most effective technique to avoid this is to flush the system on a regular basis.

How Often Should You Flush Your Water Heater?

  • At the absolute least, you’ll want to flush the system once a year, if not more frequently.
  • However, it is dependent on the composition of your local water supply as well as the equipment you have in your house.
  • In order to obtain information regarding the drinking water in your area, contact the Environmental Protection Agency (EPA).
  • If you have a high-efficiency water softener installed, your heater may not need to be flushed as frequently since the softener will lessen the amount of sediment that accumulates.
  • Water heaters in Phoenix have an especially difficult time dealing with sediment since the state of Arizona has some of the toughest water in the United States.
  • As a result, if you do not have a water softener installed, you may want to flush the heater as frequently as once or twice a month or two in order to prevent problems.

Signs It’s Time To Flush Your Water Heater

Water heater flushing on a regular basis is a successful technique, but it is also beneficial to be aware of the warning signals that suggest a flush is necessary in order to avoid costly repairs later on. Here’s a brief review on what each of these indications means.

You Can’t Get Hot Water

If you are having trouble getting hot water from your heater, it is possible that sediment has accumulated within it to the point where it is either preventing the element from lighting or stopping the heat from passing to your water. Regardless of the situation, this is a hint that you need to flush the heating system.

Your Water Heater Is Making Strange Sounds

It is possible that silt can cluster together and create calcified stones that will smash against the sides of your water heater in areas where water is very harsh. This is a warning indication that you should flush the heater before the stones grow to such a size that they choke the drain line.

Your Water Smells Funny

  • While sediment accumulation is often the most serious issue you should be concerned about when cleaning your water heater, germs can also form within a tank that has not been flushed in a long period of time if the tank has not been cleaned.
  • This bacteria has the potential to cause a strange odor in your water.
  • Not only will you need to flush the tank, but you’ll also need to sterilize it, which we’ll go over in more detail in the next section.

How To Clean Your Hot Water Heater: The Process

When cleaning your water heater, you will need to open many taps around your home and allow the water to drain entirely out of the tank. This is a necessary part of the process. Cleaning your hot water heater is actually pretty simple if you follow the correct procedures. You’ll discover that these procedures become second nature to you as time goes on.

Step1: Prepare The Heater For Flushing

  • Before you do anything else, be sure that the thermostat on your water heater is turned off.
  • For many tanks, merely switching to ″Pilot″ mode will suffice to get the desired results.
  • As a result, you will not have to go through the hassle of reactivating the pilot light, which is a simple but time-consuming task.
  • You will also avoid the need to turn off the gas if you follow this procedure.
  • It will be necessary to turn off the electricity to your water heater if you have one.
  • The proper switch will be located on the device.

Last but not least, turn off the cold water supply.The valve for this operation is normally found on top of the heater, which makes sense.

Step2: Open The Hot Water Faucets In Your Home

This will aid in the drainage of the tank. If you do not complete this step, a vacuum will build in your tank, which will keep the water trapped within. It’s a strange physics effect, similar to how water remains caught in a straw if you maintain your finger on the tip of the straw while drinking.

Step3: Connect A Hose To Your Tank’s Drain Valve

  • The drain valve should be situated near the bottom of the tank, preferably on the side.
  • In order to avoid damaging your home’s foundation, you’ll want this hose to either lead into a very large container or (ideally) to the outside and away from it.
  • If you use a little bucket, you run the chance of flooding your basement or the area where the tank is located, which is not ideal.
  • If your basement has a drain, you may be able to divert the water to it by placing the other end of your hose near the drain and directing it there.

Step4: Open The Drain Valve And Let The Tank Empty

Depending on how much sediment has accumulated in your tank, you may be able to see bits of sediment being discharged from it as they pass through. With increased frequency of cleaning, you’ll be able to determine whether or not you’re maintaining a high level of consistency based on the quantity of sediment that comes out.

Not Getting Any Water Out Of The Tank? Try This!

You will not see any flow if you open the drain valve when there has been an excessive buildup of silt in the tank, which has clogged the drain valve. To correct the situation, use a wet/dry shop vacuum to remove the obstruction. The majority of the time, this will enough. If it does not, the situation may necessitate the involvement of a professional.

Step5: Reactivate The Cold Water Supply

Before you unplug your hose from the drain valve, be sure the cold water supply has been reactivated. This water will aid in the dislodgmentation of any further sediment that may have accumulated in your tank. Continue to allow for a few minutes of drainage until the water escaping from the hose is clean. (Optional) After that, switch off the cold water supply one more time.

Step6: Shut The Drain Valve Off

After you have disconnected the garden hose from the drain valve, turn the valve back on before turning on the cold water supply.

Step7: Close The Faucets After A Minute Or So

During the refilling process of your water heater’s tank, you may notice that discolored water is coming out of your faucets. If you wait a minute or two, this should be resolved. Once this has occurred, you may turn off the faucets.

Step8: Return Your Water Heater To Its Ready State

It entails resetting the thermostat to its default setting, relighting the pilot light if you chose to turn it off, and re-connecting the electricity if you’re using an electric heater to complete the task.

How To Clean A Hot Water Heater With Vinegar

You may need to use vinegar to cut through sediment accumulation if you suspect that your water heater has become seriously clogged with sediment. As far as how to clean a hot water heater with vinegar is concerned, the procedure is simply a few steps longer than what we previously described in detail. Before you proceed with the actions outlined above, do the following.

Remove The Anode Rod

Please refer to your tank’s owner’s handbook for the specific procedure to be followed. In most cases, a recessed bolt will require the use of a wrench to be unfastened.

Use A Funnel To Place Vinegar Inside The Tank

When you remove the anode rod, you will see a hole in the area where it was previously located. This is the location where the funnel should be placed. Fill the tank with no more than four gallons of vinegar after passing it through this funnel.

Replace The Anode Rod And Activate The Cold Water Supply

Reinstall the anode rod and turn on the cold water supply again. This will cause the tank to fill up with water again. Make sure to let the tank remain with the vinegar-infused water for the whole 24-hour period. During that time, the acidity of the vinegar will begin to work its way through the sediment.

Go Through Steps1 through8

To completely remove the vinegar (as well as any sediment that should have dissolved) from your tank, follow the instructions in steps 1 through 8 to the letter.

How To Clean A Tankless Water Heater

  • The fact that your water heater does not have a tank does not rule out the possibility of silt and minerals accumulating inside it over time.
  • Essentially, a tankless heater does not store water and instead heats it on demand, as the name suggests.
  • As a result, becoming familiar with the process of pumping water into the system and then directing it out is essential to knowing how to clean a tankless water heater.
  • The following are the steps to follow in order to do this correctly.

Step1: Switch The Power And Gas Off

To begin, turn off the electricity and gas (if your tankless heater is powered by gas).

Step2: Remove The Unit’s Panel And Test The Electricity

It is possible to detect whether you have correctly unplugged the electricity from the tankless water heater by using a no-contact electrical tester. This is a safety measure in case you accidentally turned off the wrong switch on your circuit breaker. It will alert you if you have done so. Once you are positive that the electricity has been turned off, go to the following step.

Step3: Turn Off The Water Supply

Shut down the water supply line that runs directly into your tankless heater.

Step4: Connect The Hoses

  • In contrast to a traditional water heater with a tank, you’ll have to actually bring water into your tankless heater as part of the cleansing process.
  • That is why you will require two hoses.
  • There are two connections: one links the unit to a pump (which pumps water into it) and another connects the unit to an isolation valve (catching the water as it expelled from the tank after making its way through).

Step5: Prepare A Five-Gallon Bucket With Your Pump And Hose

Prepare the vinegar by filling a five-gallon bucket halfway with vinegar and placing your pump and the open end of your second hose inside.

Step6: Let The Pump Run For An Hour

Turn on the pump and let it running continuously for an hour. The pump will circulate the vinegar through your tankless heater in a closed loop configuration. Hopefully, the steady flow (together with the acidity of the vinegar) will be powerful enough to wear away at any built-up sediment in your heater.

Step7: Remove The Pump And Activate The Cold Water Supply

You should now be able to leave the end of your second hose in the five-gallon bucket, which should be completely empty of any vinegar. Before turning off the cold water supply, let the cold water run through the system and into the bucket for about five minutes before turning it off.

Step8: Return Your Tankless Heater To Its Operational State

Disconnecting the hoses, replacing the panel, and reactivating the water supply valves are all steps in this process. The final step should be to re-establish electrical power to the device.

How To Clean Out Your Water Heater: Conclusion

  • By the end of this article, you should have gained an understanding of the fact that knowing how to clean out your water heater does not involve any specialist knowledge of the system.
  • You should be able to do this task without difficulty if you follow the procedures outlined above.
  • To summarize, let’s take a look at some of the specific considerations you’ll need to make based on the sort of water heater you have.

How To Clean An Electric Water Heater: Special Considerations

The procedure for cleaning an electric water heater is much less complicated than the procedure for cleaning a gas water heater. Because everything is powered by electricity, you won’t have to relight the pilot light when you’re finished with it.

How To Clean A Gas Water Heater: Special Considerations

As far as the proper way to clean a gas water heater is concerned, there are two important aspects to keep in mind. Before beginning the operation, you must turn off the gas valves in the house. Because turning off the thermostat will deactivate it, you will also need to relight the pilot light after you are finished.

Cleaning A Tankless Water Heater: Special Considerations

The fact that your heater does not have a reservoir for fluid means that you will need to introduce water and clean it out.

  • If you have an electric water heater, make sure the power switch is turned off before continuing.
  • Ensure that your water heater is a gas heater, such as the one seen in the photo above, by setting your thermostat to ″pilot.″ This shuts down the heating element in your water heater, allowing the water to cool down as a result.
  • Ensure that no one in your home is currently attempting to take a shower, wash dishes, or do a load of laundry before beginning this home repair chore.

2. Turn the Cold Water Valve Off

  • Close the cold water valve and turn it off.
  • When cold water is introduced into the tank and dispenses with the hot water, the water heater circulates the hot water around your home.
  • You may entirely empty your tank of water if you don’t have any cold water coming into it from outside.
  • If you skip this step, you’ll wind up with water constantly flowing into the tank and down the drain, which might result in a significant increase in your monthly water bill.

3. Let the water cool.

Don’t dump scorching hot water down the drain. Allow the tank to cool after the heating components have been turned off. Some bigger water heater tanks might take up to two hours to complete the process.

4. Attach a drain or garden hose to the drain valve on the side of the tank

Drain your water heater by connecting a hose to the drain valve located on the side of the unit. Make certain that the hose is properly screwed on, otherwise you may experience leaks when you drain your water heater tank from the faucet.

5. Place the end of the hose in a bucket or drain.

Don’t let your house flood! Make sure to place the hose’s end in a heat-resistant pail or down a drain when you’re finished. Before you begin emptying the water heater, check to be sure that your drain will not overflow while doing so.

6. Turn on a faucet (or two)

The use of faucets around your house might help prevent a vacuum from accumulating inside your plumbing system. Turn on the ″hot″ setting on your faucets and leave them running. Due to the fact that you have shut off the cold water valve to your water heater, there will be little or no warm water displaced through them.

7. Start draining the tank by turning on the drain valve.

Turn the valve on carefully with a flathead screwdriver, making sure there are no leaks and that the bucket or drain you are emptying the water into is not going to overflow while doing so.

8. After the water heater tank has finished draining the sediment, turn the drain valve off, remove the hose, turn the cold water valve on, and turn the heating elements in the water heater back on. 

  • You are almost through with your water heater cleanup once you have thoroughly emptied it and removed all of the debris from the tank.
  • In order to refill your tank, close the drain valve and remove the hose from the tank.
  • Turn the cold water valve back on and the heating elements back on by turning the knobs on the thermostat.
  • Check to see that your faucets are still turned on, and after the water is flowing normally again, turn them off.
