A water heater is one of the hardest-working appliances in your home, and in San Diego's hard water it takes a beating. A little maintenance is the difference between replacing it at 8 years and getting 12+.
1. Flush it once a year
This is the big one. Sediment and scale settle at the bottom of a tank, insulating the burner and forcing it to work harder (that's the rumbling sound). An annual drain-and-flush clears it out, restores efficiency, and protects the tank. In our hard water, skipping it is the fastest way to a short life.
2. Check the anode rod
The anode rod is a sacrificial metal rod that corrodes so your tank doesn't. It wears out over a few years. Replacing a spent anode rod is cheap and can dramatically extend the life of the tank — one of the most overlooked moves in all of home maintenance.
3. Test the T&P relief valve
The temperature-and-pressure relief valve is a safety device. It should be tested periodically to make sure it isn't stuck. A valve that constantly drips, though, can signal a pressure problem worth checking.
4. Set a sensible temperature
Around 120°F is the sweet spot — hot enough for comfort and safety, not so hot it wastes energy, scalds, or accelerates scale.
5. Keep the area clear and look for drips
Give it airflow, keep boxes away from a gas unit's base, and glance underneath now and then. A little rust or moisture is an early warning worth acting on.
Never flushed your heater, or not sure when it was last serviced? give K2 a call — a tune-up now is a lot cheaper than a replacement later.
