3 Water Heater Maintenance Tips

Your water heater is one of the most important parts of your home – it’s used for everything from showering to doing laundry to washing dishes and more, which is why it’s important to maintain it. Learning how to do simple maintenance on your water heater can extend its lifespan and keep it running smoothly all year long. Here, our water heater experts share some tips:

Checking the Pressure Valve

Whether you have an electric water heater or a gas-powered water heater, you’ll find a safety devices called a temperature and pressure relief valve. It’s important to make sure this valve is operating correctly because if it’s not, it can mean an explosion.

First, turn off the power to the water heater and shut off the cold-water inlet. Next position a bucket of water underneath the valve and pull up the lever. (You should hear a rush of air and see some water vapor.) If water continues to flow out of the valve, drain the tank partway, unscrew the old valve, and replace it with a new one.

Replacing the Anode Rod

A water heater’s anode rod protects the exposed steel of the water heater when the tank is filled through a method called electrolysis. Because the rod protects from rust, it can become coated with calcium carbonate and should be replaced.

Start by connecting a garden hose to the tank’s drain valve and open the pressure relief valve and the drain valve. Let a few gallons of water drain out and close the drain valve. Next, look for the hex head of your anode rod on top of the heater or under the top plate. Once you locate it, fit a 1 1/16-inch socket onto the head and unscrew the rod. Examine it – if it’s less than 1/2 inch thick or covered in calcium carbonate, buy a new one, wrap its threads with Teflon tape, and replace the rod.

Flushing the Tank

As your water heater gets older, sediment will begin to settle in the tank and not only reduce the heater’s efficiency, but clog the lines. This is why you should flush your tank on a regular basis.

First, start by turning off the power to your water heater and shut off the cold-water inlet. Connect a garden hose to the tank’s drain valve and make sure the other end of the hose is in an area that won’t be negatively affected by hot water. Open the pressure relief valve, then open the drain valve. Let the tank drain completely and close the relief valve and drain valve. Turn the cold-water inlet back on and open up all hot water spigots in your home to refill.
