A typical water heater maintenance procedure is as follows:
- Power and water supplies disconnected
- Water tank drained
- Anode rod condition checked
- Pressure relief valve examined
- Thorough inspection for leaks
- Temperature adjustments, as needed
- Ventilators scrutinized for damage
- Power and water supplies restored
Between maintenance appointments, you should keep an eye out for telltale signs of trouble. Unusual noises from the unit, discolored water and temperature fluctuations warrant a call to a professional plumber. If your unit operates on gas, ensure the pilot light remains steady and there are no detectable gas odors.
If you do notice a gas smell, evacuate the area immediately. Lastly, although repairs cost, they’re cheaper than a hot water heater installation that replaces one that may have lasted longer.
