Water Heater Maintenance Checklist — Wilmington, Delaware

Lift the lever on the temperature/pressure relief valve. Water should flow freely and stop when released. If not, replace.

Remove and inspect the anode rod. Replace if less than 1/2 inch thick or coated with calcium. This rod prevents tank corrosion.

Connect a hose to the drain valve and flush until water runs clear. Removes sediment that reduces heating efficiency and tank life.

Set to 120°F for optimal balance of comfort, energy savings, and scald prevention. Each 10°F reduction saves 3-5% on heating.

Check all connections, the T&P discharge tube, and the tank bottom for moisture or corrosion.

Check that the vent pipe is properly connected, slopes upward, and has no rust holes or obstructions.
