How to Flush a Water Heater

Nothing is more relaxing and rejuvenating than soaking in tub full of hot water or having a warm shower cascade over you at the end of a long, tiring day.
If you want the water heater in your house to continue working effectively and efficiently, then it’s essential to periodically flush the heater. That’s because minerals deposit over time and can build up into large, thick rusty lumps.

Not only does that hinder the heat exchange between the burner and the water, but it also leads to corrosion and possibly other severe pipe blockages throughout your house.
Instead of looking for a plumber and waiting for them to do the job, flush the water heater yourself.
It’s simple, easy and only takes a couple of minutes to an hour at most.

Follow the steps below to be guided through the process.

1. Turn off the heat

Whether it’s a gas or an electric powered water heater, turn the heating knob to off to stop the water in the tank from continuing to heat.

Turn off the water inlet valve. You don’t want continuous flow for now.

After switching off the heat and double checking to make sure the tank did not fill up any further, you’re ready to proceed.

Wait for some time before going on to the next step so that the water already present in the tank has a chance to cool down.

2. Attach a pipe to the drain valve

At the bottom of your water heater, you will see a drain valve. It’s that thing with the threads on it that looks kind of like the end of a garden hose. Without opening it yet, fix one end of a hose or garden pipe to this drain valve. Snug it up like you would any hose to attaching to an outside faucet for example.

Run the other end of the hose or pipe, whichever you used, out into your garden or down to a drain or into a large bucket. Make sure that the end of your hose is lower than the drain valve so that water can easily flow out due to gravity.

3. Open a hot water tap

Turn open one of the hot water faucets anywhere in your house. Some people prefer the one farthest from the water heater. Then open the water heater’s pressure-release valve, usually on top of the heater. That will let air enter the heater, releasing any pressure, and allow the water to drain out.

You might consider collecting the draining water in a bucket to be a good conservationist and avoid wasting the water. You can use it to do dishes, soap up your car, water plants, or any other purpose.

4. Turn on the drain valve

Drain out about 5 gallons of water until the water from the drain valve appears to run clear.

This ensures you got most of the sediment removed.

5. Close the valve

Once the heater is relatively emptied, close the drain valve and return it to its former position. Also, close the pressure-release valve on top of on your water heater.

Close that hot water faucet you turned on in your house and be glad you did so you don’t have water needlessly running when you fire everything back up!

Switch on the main water supply to the heater and wait for the tank to fill.

Now, turn on a hot water faucet on again to bleed air out of the water system and to ensure that the tank has been filling. Note that this water will not be warm yet because the heat is still off.

If you have water running reliably at the faucet from the previously emptied hot water heater, then go ahead and relight the pilot (on gas-powered heaters) or turn on the electronic ignition (for electrical heaters)— as the case may be.

Your clean hot water supply is back!

Now, that super easy after all!
So, don’t further delay cleaning out your water heater. Flush out it out today and save yourself from future troubles.
