| Task | How often |
|---|---|
| Check for leaks and rust around the tank | Every few months |
| Test the temperature and pressure relief valve | Once a year |
| Flush the tank to remove sediment | Once a year |
| Inspect the anode rod | Every two to three years |
| Check the burner and venting (gas) | Once a year |
| Set the thermostat to about 120 degrees | Once, then check yearly |
Flushing the Tank
Sediment collects at the bottom of the tank and reduces efficiency. A yearly flush removes it. Turn off power or gas, connect a hose to the drain valve, open it and let the tank empty until the water runs clear. Hard water speeds buildup, so some homes benefit from flushing more often.
Hot water can scald. Let the tank cool and run the hose to a safe drain.
The Anode Rod
The anode rod corrodes in place of the tank steel. Once it is gone, the tank begins to rust. Checking it every few years and replacing it when worn is one of the best ways to extend tank life.
Testing the Relief Valve
The temperature and pressure relief valve protects against dangerous pressure. Lift the lever briefly to confirm water flows and the valve resets. If it leaks, sticks or does not move, have it replaced.
Burner and Venting Checks
On gas heaters, check that the flame is blue and steady and that the vent is clear. Yellow flames or soot mean the burner needs cleaning. Our guide to gas water heater repair explains common burner and pilot problems.

Water Heater Maintenance Questions
How often should a water heater be serviced?
Once a year is a good rule, with flushing and a valve test.
Does flushing a water heater help?
Yes. It removes sediment that reduces efficiency and shortens tank life.
What temperature should a water heater be set to?
About 120 degrees is a common setting for safety and efficiency.
What does an anode rod do?
It corrodes first so the tank steel does not rust.
Can I maintain a water heater myself?
Basic checks and flushing are doable. Gas and electrical work should be left to a plumber.
