A few tips to check and maintain your home’s water Heater.
Give a twist to the water shut-off valve to keep it from seizing
- If it is a gas water heater, set the gas valve to “Pilot” to prevent the burners from coming on throughout the flushing process. If electric, turn off the circuit breakers.
- For gas water heater, make sure the flue is draining air properly by lighting a match next to the bell housing and watching the smoke. The smoke should be going up the flue.
Test the temperature relief
- Put a bucket below the extension pipe and open the valve, the water should flow when it’s open and stop when it’s closed.
- Set the thermostat to the recommended setting of 120 degrees F.
Make sure the pilot light on gas units and the burner flames are burning blue and steady
Flush water out of the tank
- Drain the sediment from the tank.
- Turn the thermostat down and shut off the cold water supply and open the drain valve.
- Open the temperature / pressure relief valve at the top of the tank by lifting the lever. Leave the valve open.
- Open the drain valve at the bottom of the heater allowing the water to flow out of the garden hose.
- Close the drain valve, turn on the cold water supply and set the thermostat to the recommended setting.
Open a hot faucet in the house and let it run until no air bubbles come out.
Turn the heater back on.
