System Maintenance

What general maintenance should be done on my water heater?

Professional technicians should perform most repairs and maintenance. However, here are a few measures you can take yourself:

Ensure that there are no sources of flammable vapors in the same area as your water heater (this includes gasoline, heating oils, lighter fluid, propane, etc.)

Keep the top of the water heater clean. If you notice water dripping on the water heater from any piping, contact a plumbing professional to have the leak repaired.

Keep the space around your water heater clean and free of dirt, boxes, paint cans, aerosol cans, household cleaners and trash. It is important to keep the heater accessible for proper operation and easy maintenance.

Drain 1 to 2 gallons per month.

Have the anode rod inspected periodically.

Refer to the I&O manual for complete maintenance instructions.

How do I drain my water heater?


On a gas water heater, turn the gas valve to the off position. On an electric water heater, turn the electric off to the heater.

Shut the cold water off to the water heater.

Open a hot water faucet.

Connect a hose to the drain valve on the heater and run to a drain.

Open the drain valve and allow the tank to completely drain.

Turn back on the cold water into the water heater.

Allow the water to run through the water heater and out of the drain valve. Do this for approximately five (5) or ten (10) minutes.

Close the drain valve and allow the tank to refill, keeping the hot water faucet open. When water comes out of the faucet, the tank is full.

How do I adjust the temperature on my water heater?

Locate the thermostat dial on the side of your water heater.

Rotate the dial clockwise to increase the water temperature, and counter-clockwise to reduce the temperature.

Check the I&O manual for proper operational adjustment procedures.

How often are you supposed to flush the water heater?

You should flush your hot water tank once every 6 months. If your local water is harder or contains more minerals, you may need to do so on a more frequent basis. At a minimum, drain 1 to 2 gallons of water from the drain valve monthly.
