How to Perform Annual Maintenance on your Water Heater
Step 1: Test the pressure relief valve on the top or side of the water heater. This valve will open if the internal pressure of the tank gets too high.
Step 2: Place a bucket under the valve and turn it. If the valve does not release water, you need to replace the valve.
Step 3: Next, close the cold water supply pipe that feeds the water heater.
Step 4: Turn on the hot water at any faucet to release the pressure inside the heater’s tank. Leave faucet on until you are finished.
Step 5: Electric Water Heaters – turn off the power to the main panel.
Gas Water Heaters – turn the gas control dial to “off”
Step 6: Drain Sediments from the Hot Water by releasing about 2-3 gallons of hot water from
the tank. These sediments build up over time and can mean a short life-span for your water heater and less efficiency and higher bills for you. Let the water flow until the water being released is free of sediments.
Step 7: Don’t worry about gurgling or groaning noises coming from the heater; it’s just air
entering the system as water drains out.
Step 8: To restart the water heater, open the shutoff valve and let the hot water run at any
faucet to force air out of the system.
Step 9: Turn on the power or re-light the pilot.
Step 10: Set water heater to 120 degrees Fahrenheit.
