How to Flush a Rheem Water Heater
Draining and flushing the tank of your Rheem water heater on a regular basis is one method of extending the life of your water heater and keeping it operating properly. In the course of time, silt accumulates inside the tank, resulting in decreased tank function. The length of time between flushes is determined by the hardness of your water. Once a year, most water heaters benefit from a cleansing of the system. Flushing a Rheem water heater is similar to flushing any other model of water heater.
Step 1
Turn off the hot water heater’s electrical and gas supplies by pressing the appropriate buttons. The circuit breaker is located within the electrical panel of your home. The gas shutoff valve of a Rheem gas water heater is located on the lower front of the water heater.
Step 2
Using your hand, turn the cold water supply shutdown handle counterclockwise to halt the flow of water to the water heater.
Step 3
Attach a garden hose to the drain valve on the water heater tank with a hose clamp. When installing a Rheem water heater, look for the drain valve, which is often located on its bottom half, to its right of the gas valve or below the lower electrical panel door. Alternatively, you may place the opposite end of the garden hose into an adjacent bathtub or outdoors through an external door. While the tank is being drained, keep children and dogs away from the garden hose to avoid injury.
Step 4
Turn on the hot water at the tap closest to the water heater to save energy. Drain the water from the tank by turning the drain valve handle counterclockwise and allowing it to drain through the hose.
Step 5
When the water in the tank has been entirely emptied, turn on the cold water supply valve. Water should be allowed to circulate through the tank and garden hose until the water becomes clear.
Step 6
Close the drain valve gently, allowing the tank to fill with water while it is being filled. The handle of the open faucet should be turned off after the water is flowing consistently through it.
Step 7
Allocate time for the water heater tank to completely fill before disconnecting the garden hose from the drain valve. Activate the electricity and natural gas supplies. Relight your pilot light according to the instructions in your Rheem owner’s handbook for your particular model.
Tip
Using a plumbing electrical pump, you may thread the garden hose through a window if necessary. If you have hard water, Rheem recommends emptying a few quarts of water once a month to eliminate mineral deposits from the system.

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.
Materials
- Drain valve (if necessary)
- Threaded hose cap (if necessary)
- Drain valve (if necessary)
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 to a bucket in order to collect the water and sediment that will be emitted from the faucet.
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. To relieve pressure in the system, keep a hot water faucet open in the sink closest to your hot water heater.
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 procedure as many times as necessary to completely empty the tank.
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. As soon as the outflow is free of silt, it will be evident that you have completed the process and may proceed to the following stage.
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.
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.
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.

How to Unclog a Drain Valve: 7 Ways to Get the Water Flowing
As an Amazon Associate, we receive a commission on qualifying purchases made via our links. Find out more. When your water heater won’t drain, the most likely reason is that the drain valve has become clogged. This is usually the result of an excessive amount of silt accumulating within the tank. During the heating process, the minerals present in the water separate and settle to the bottom of the water heater. If the sediment in the tank is not removed on a regular basis, it will not only diminish the effectiveness of the device, but it can also clog the drain valve, causing the water to become trapped within the water heater.
If left ignored, it will eventually need the purchase of a new water heater since the sediment will corrode the interior of your tank and cause an unrepairable leak.
7 Methods to Unclog a Drain Valve
In order to verify if your water heater drain valve is genuinely clogged, you must first ascertain whether it is. Take the following steps:
- Turn off the fuel supply for your water heater (electric: turn off the power to the water heater). Turn off the circuit breaker (in the case of gas, turn the on/off control knob to the off position)
- Drainage should be connected to the drain valve and the valve should be OPENED. DEPRESSURE IN THE TANK: OPEN a hot water faucet inside your home (and leave it open) to allow the negative pressure to escape
- It is unlikely that your valve is clogged if the water drains and turns clean. Clogged valves cause the water to dribble or not drain at all
- This indicates that the valve is clogged.
Caution is advised since there is a strong likelihood that the water in the tank is extremely hot. To avoid being burnt in this situation, you should take appropriate safety steps before proceeding. When attempting to drain a water heater, always use work gloves and safety eyewear to keep yourself safe. Additionally, the water should be allowed to cool before being drained. There are numerous techniques for cooling the water inside the tank, which are as follows:
- It is necessary to turn off the natural gas or electric supply to the water heater and let it sit for up to 24 hours. To check if your water heater is not entirely blocked, remove all of the water that you can from the drain valve while leaving the water inflow valve open. Cold water will be able to enter your tank and dilute the hot water as a result of this. It is necessary to cut off the fuel supply (gas or electricity). If your water heater is entirely blocked, you can draw hot water from the tank by opening the hot water taps in the kitchen and bathroom. Keep the cold water intake valve open to allow the hot water to cool down to a more comfortable temperature. It is necessary to cut off the fuel source (gas or electricity) in order to prevent the water from warming.

How to Unclog a Water Heater Drain Valve
There are a variety of methods for draining a clogged water heater tank, and the degree of the blockage will play a significant factor in selecting which approach is most effective. Begin with the simplest item on the list and work your way down to the more difficult items. Take note that the water in the tank is most likely quite hot, so take precautions to avoid getting burned by following the safety guidelines stated above.
Before you begin, make sure that the water heater’s power supply is turned off. If you have an electric water heater, turn off the circuit breaker; if you have a gas water heater, turn the on/off control knob to off.
Wait
If your drain valve is clogged, the first thing you should do is to wait it out. Occasionally, the weight of the water within the tank will be sufficient to dislodge the blockage on its own. Here’s what you should do:
- Continue to leave the drain valve open while the hose is connected. Close all hot water faucets in the home except for one. Continue to wait for an hour or so to observe whether the tank begins to drain.
Wire Coat Hanger
If waiting doesn’t work to unclog your drain valve, the next step is to use a wire coat hanger to clear the obstruction.
- Close the drain valve and take the hose out of the system. Under the drain valve, a small pail or a couple towels are a good idea to keep the water from backing up. Make use of a sturdy wire, such as a wire coat hanger, for this project. Drain the tank by opening the drain valve and inserting the wire through the valve hole into the tank. Move the wire in a circular motion to try to dislodge any debris that has accumulated. If you are successful, the water will begin to flow out of the tank
- Otherwise, nothing will happen. Once you have a steady flow of water, you may close the valve and connect a hose to allow the tank to drain completely. Before your tank is totally empty, the valve may become clogged again
- However, you may just repeat the operation.
Watch the Video
Stomping on the hose may help if your drain valve is still not working properly.
- As soon as you have connected the hose to the drain valve, stand firmly onto the hose around 2 feet away from your water heater
- If the sediment is the source of the blockage, an air bubble will be blasted back into the tank, clearing the obstruction and unclogging the valve. You shouldn’t be surprised if the drain valve becomes clogged once more when you are attempting to drain the tank. Basically, you just have to keep repeating the process until the tank is totally emptied.

If none of the procedures listed above were successful, it may be necessary to attempt back cleansing your water heater. Here’s how it’s done:
- Fill the hose with water from a washing machine. On both ends of these hoses, there is a female connector. DON’T forget to close the drain valve and attach one end of the wash machine hose to the valve. Use a garden hose to connect the other end of the hose to a nearby washtub faucet (washtub faucets are commonly threaded) or to an outside faucet (and connect the garden hose to an outside faucet)
- Turn the water supply to the faucet on. OPEN the water heater’s drain valve and allow the water to flow into the tank for 10 to 15 seconds
- OPEN the water heater’s drain valve and allow the water to flow into the tank
- In order to unclog the valve, water from the hose should be used to drive the silt away from the valve. Close the drain valve and turn OFF the water at the faucet to prevent a puddle from forming. Unplug the hose from the faucet (leave the line attached to the drain valve, or use a garden hose to drain the tank)
- OPEN the water heater drain valve and allow the water to drain from the tank. It’s possible that your blockage is too severe or that your drain valve is malfunctioning, in which case you’ll need to replace your drain valve.

If backflushing does not resolve the issue, it may be necessary to replace the drain valve. It IS feasible to change the drain valve while your tank is still full with water if the procedure is followed correctly. Here’s how it’s done:
- A replacement drain valve (preferably brass) should be purchased. Tape the threads of the replacement drain valve with Teflon tape. Check to make sure that ALL of the faucets in your home are closed. When this happens, your water heater will generate a vacuum, which will prevent the water from “pouring out.” Place a bucket and a few towels beneath the drain valve to catch the water. To open the drain valve, use an adjustable wrench to turn it. Remove the drain valve one turn at a time. Keep in mind that some water will be dripping from your tank. Even if your tank is completely blocked, you will very certainly have some water escaping from it. If, on the other hand, the problem is a defective drain valve, you will almost surely have water. Insert the replacement drain valve as soon as possible. This shouldn’t take more than a few seconds. To drain your tank, just connect it to the new drain valve using a garden hose
- We propose that if you’re going to go to the trouble of changing your drain valve, you consider replacing it with a ball valve to save time and effort (see below). Your drain valve will never clog again, and you will never have to worry about it again.
Many water heaters are equipped with low-cost plastic drain valves. You should replace it with a high-quality brass valve, such as this one from Rheem, if you find yourself in this situation.
Replace the Drain Valve with a Ball Valve
It is substantially larger than a conventional drain valve to operate a ball valve. Replace your drain valve with a ball valve to not only clear your tank, but you’ll also prevent sediment from blocking it in the future as a result of the replacement. The following steps will show you how to replace your drain valve with a ball valve:
- Purchase a 3/4″ abrasive ball valve as well as two 3″ dielectric nipples. (The nipples have been covered with acrylic to keep them from rusting). Each nipple will be attached to one of the ball valve’s two halves. Make use of teflon tape on the threads of the nipples that screw into the ball valve
- And Keep in mind that the ball valve’s handle should be turned away from the tank when it is opened. Teflon tape should be applied to the second side of one of the nipples (just three of the four threads on each of the two nipples will be lined with teflon tape). Check to make sure that ALL of the faucets in the home are closed. When this happens, your water heater will generate a vacuum, which will prevent the water from “pouring out.” Place a bucket and a few towels beneath the drain valve to catch the water. Loosen the drain valve by turning it with an adjustable wrench. Remove the drain valve one turn at a time. Keep in mind that some water will be dripping from your tank. Even if your tank is completely blocked, you will very certainly have some water escaping from it. If the problem is caused by a defective drain valve, you will almost likely have water on your hands. Insert the new ball valve as soon as possible. This shouldn’t take more than a few seconds. Connect a garden hose to your tank and drain the contents
- You should either replace the ball valve with a conventional drain valve or remove the handle for the sake of safety once your tank has been drained completely. It is possible that the handle will be accidentally opened, resulting in the draining of your tank. This has the potential to cause water damage and/or significant burns.
Make the purchase of two dielectric nipples and a 3/4″ abrass ball valve. For rust prevention, the nipples are covered with plastic. Each nipple will be attached to one of the ball valve’s two halves: Make use of teflon tape on the threads of the nipples that screw into the ball valve, and Take note that the ball valve’s handle should be turned away from the tank while in use. To line one of the nipples with teflon tape, place it on the second side (just three of the four threads on the two nipples will be coated with teflon tape); Check to make sure that ALL of the faucets in the home are CLOSED before proceeding.
- Disengage the drain valve with an adjustable wrench; Remove the drain valve slowly by unscrewing it.
- If your tank is blocked, you will almost certainly have some water leaking out of the opening.
- Replace the ball valve as soon as possible.
- Pour out the contents of your tank using a garden hose You should either replace the ball valve with a conventional drain valve or remove the handle to ensure your safety once the tank has been drained.
You might unintentionally deplete your tank if the handle is accidentally opened. This has the potential to cause water damage and/or significant burns; nevertheless,

Water Heater Flush: How To Do It Safely and Easily
Your water heater is responsible for delivering all of the necessary hot water to your home when you require it. You may only understand how crucial a piece of equipment is when it is not functioning properly or is backed up in some way. In order to guarantee that your water heater is operating at peak performance, you must ensure that it is thoroughly flushed and cleaned. For the purpose of assisting you in understanding the fundamentals of water heater flushing, we will first discuss why it is so important and how frequently you should perform it.
Why Do You Need to Do a Hot Water Heater Flush?
Water heaters begin to acquire silt and accumulation that is naturally contained in the water supply over lengthy periods of time of usage. Sediment can accumulate in the heater and clump together, resulting in decreased efficiency or damage to the device, depending on the circumstances. When it comes to water heaters in Phoenix, where the water is extremely sediment-rich, this is a regular occurrence. When you flush out your heater, you are preventing excessive sediment building and ensuring that you are able to use the unit more efficiently while experiencing less fear about failure.
Water Heater Flush Cost
As you’ll see, a water heater flush is really inexpensive when you consider that it can be completed in a matter of minutes by following a few simple procedures.
How Frequently Should You Do a Hot Water Heater Flush?
If you consider how important your water heater is, you should not put off cleansing your system for an extended period of time. Every water heater has a varied lifespan, but making sure you clean out your water heater on a regular basis can help it last as long as it was designed to. A flushing of your heater should be done every couple years or so, on average. In order to guarantee the optimum performance from your unit, flushing it once a year is recommended, and the following instructions will demonstrate how simple it is to do.
Steps for Performing a Water Heater Cleanout/Flush
Your heater, like any other item in your home, will require some level of electrical power to operate properly. Depending on your unit, you may only need to complete one of these procedures during a water heater flush, or you may need to complete all of them. By turning off your gas, you can assure that the machine is not getting any gas and will not overheat or leak as a result. In most cases, turning off the electricity to your unit may be accomplished through your circuit breaker, which should include a switch labeled for the heater.
As you work on the equipment, this will help to avoid any electrical problems from developing. Keeping this step in mind will help to provide a safe working environment for whoever is responsible for finishing the flush.
Open a Hot Water Faucet
This is accomplished by tricking your system into believing it is required to be running, which requires you to open a hot water tap in your home. Despite the fact that water will flow out, it will not be heated at the time of the process. In addition, this procedure is critical because it prevents a vacuum from accumulating in the pipes, which might result in the formation of undesired air bubbles in your water system.
Turn Off the Cold Water Valve
Your water heater will have a supply valve that will connect to the unit and be used to feed cold water to the unit. You will want to turn off this valve while you are completing the flush. It should be positioned on or near your unit, and it will usually be towards the top of the unit’s interior. It will have the appearance of a typical faucet valve, with the possibility of being dyed blue to indicate cold water. It is important to turn this valve off during the flush process to avoid water running into the unit, which would make the whole procedure a lot messier.
Connect a Hose to the Heater
Find the location of your spigot as the next step. This will be located at the bottom of the unit and will seem to be a standard hose faucet in appearance. You may want to set a bucket below this before proceeding with the rest of the project because it may begin to drip as soon as the lid is removed. It is necessary to locate a garden hose that can be screwed onto this spigot since this is the most convenient method of draining the system. If your water heater is located higher up in your home, gravity should be able to facilitate the flow of water.
Make certain that the hose’s end is placed in some form of pail or containment area to prevent it from spilling everywhere.
Water Heater Flush for Sediment: Drain the Tank
It is at this point that you may begin draining the unit by turning the faucet to which the hose has been connected. It is possible to see the circumstances that your heater may be encountering when the water drains out of the tank during this period of time. If the water is largely clear and typical in appearance, it is likely that your water heater is in good working order. Water that is deeper in color and that contains silt, on the other hand, might be a much greater problem. The inside of the tank might be in far worse shape than you can remedy with a simple water heater flush for sediment if you are emptying the tank and a large amount of solid material is coming out of the tank.
This step will be skipped if you are flushing a tankless electric water heater, which is the most common scenario.
Flush the System
Now that the water has been removed from the system, you will begin the process of flushing the unit. Keep in mind that you already switched off the cold-water spigot. This is what you will be turning back on in order to allow the new water to clean out the system properly. It is recommended that you drain the old bucket and thoroughly inspect it for sediment before refilling it with the fresh cleansed water. Remove the tank’s fill valve and flush it for a few minutes until the water pouring out seems clean and typical.
This will signal that the system has been completely cleansed and that the procedure is nearly completed. Always remember to switch off the cold-water supply before unhooking the hose and removing the bucket from the sink.
Reactivate Power and Gas
Now that the flushing has been completed, it is time to clean up. The first step is to cut off the drain to which the hose was attached in order to prevent any water from escaping through it. Also, remember to turn off the hot water tap in your house that you opened at the beginning of this process as well. Replace the cold water supply valve and let the tank to re-fill with cold water. When your tank is full, you’ll want to open the pressure valve on the tank to allow the air to leave for the machine to function properly.
Finally, re-start the gas and water lines heading to the storage tank.
Conclusion
Congratulations! This means that you have done all of the necessary procedures to cleanse your water heater in a reasonably short period of time. Now that you have a better understanding of the procedure, you will be better prepared the next time your heater requires flushing. The time spent flushing your heater will guarantee that it operates at peak performance and that it serves you for many years to come.
