Keeping your water heater in good working order is essential to any home. Maintaining your water heater is a relatively simple process as long as you don't put it off for too long. Even better, keeping a maintenance schedule can help you to keep track of your various maintenance requirements.

Pressure relief valve

The pressure relief valve is a release valve on the top of your water heater that is meant to keep you safe if your water heater builds up too much pressure. As well, this valve will release if the temperature exceeds the maximum level it should.

This valve should be tested once a year to ensure that it is perfectly in order. There is a lever on the top of the relief valve. If you raise it, you should hear that there is water rushing through the drain line. If you can hear this, your valve is working properly. Slowly lower the lever to close the valve, so as not to damage the relief valve.

Anode Rod

Within each water heater, there is an anode rod. This anode rod will deteriorate over time. You should check the anode rod every year to make sure that it hasn't deteriorated completely. If it has you will need to have it replaced by a professional.


Your water heater should be drained before you flush or clean the system. First turn off your heater, either by the control knob or by the breaker box. Next, turn off the water. Finally, attach a garden hose to the drain valve and open the drain valve on the bottom of the heater. This will either be a plastic toggle, or will require a flat screwdriver to open a screw that keeps the drain shut. This should allow the water to drain out through the hose.


Flushing the water heater is very simple. All you need to do is turn on the water supply and let the tank fill with 5 gallons of water, then turn off the water supply and let it drain. Do this three or four times, or until the water runs clear. Flushing should be done every four months or so.


Once you have drained the tank, you have to remove the drain valve and insert a brush into the opening in order to scrub the tank bottom. Scrub the bottom of the tank until you have loosened up all of the rust and calcium deposits. Then flush the tank a few times in order to get the sediment out of the tank. This cleaning should be done once a year.
