How To Drain A Water Heater?







Question: What is the best way to drain a water heater? My water heater has never been drained. I have a 50 gallon electric water heater that is 5 years old. I would like to flush it out for preventative maintenance purposes. I have heard that draining it will make it last a little longer. I was told by a plumber that flushing out a water heater will allow the water heater to heat the water faster and more hot water will be available. Is there anything I should know before I attempt to drain the water heater myself? Can you also tell me all the benefits of draining a water heater and how often I should flush it out? What is the easiest, safest, and best way to drain my water heater?

How To Drain A Water Heater (Electric or Gas)?

IMPORTANT NOTE: First read your owner’s manual as there may be certain specific info about your water heater.
CAUTION: When draining your water heater the water coming out WILL BE HOT! Use heavy gloves if possible.

1 – Start by turning POWER OFF to your electric water heater at the breaker OR TURN OFF THE GAS and pilot to the gas water heater.
2 – Next turn off the water supply valve that brings water flow into the water heater.
3 – Thread a heavy duty water hose to the bottom drain valve of the water tank.
4 – Put the other end of the hose in a bucket or outside where it can flow out.
5 – Turn the drain valve knob counterclockwise to open it up and let water begin to drain out.
6 – Allow the pressure relief valve on top of the tank to OPEN by pulling up on it and keep it open.
7 – Give the water tank enough time to empty all of the water.
8 – Once the water tank is emptied you will need to open the inlet water valve for 5 minutes.
9 – Allow the inlet water valve to bring water back into the tank to flush out any extra sediment build up.
10 – Once all sediment flows out of the tank and the water is clear, close the water drain valve at the bottom of the tank.
11 – Close the pressure relief valve at the top of the tank.
12 – Remove the hose from the drain valve at the bottom of the water tank.
13 – Let the water heater completely fill back up with water.
14 – If you have a gas water heater then relight the pilot to the heater and turn it back on.
15 – If you have an electric water heater you need to switch the breaker back to ON.
16 – Your water heater is now FLUSHED OUT (DRAINED) and has removed the sediment and now ready to supply you with HOT WATER.

HELPFUL NOTE: As a reminder to drain your water heater once a year use a permanent marker and write the date you flushed it out. This will let you know when the last time it was drained and will remind you when to drain it next.

Draining your water heater once a year (annually) will help to ensure hot water in your home for many more years to come.
