Common Water Heater Issues We Fix
Water heater problems tend to fall into a handful of familiar categories, and our technicians see all of them regularly.
Leaks are usually the most urgent. A leak can come from a loose fitting, a failed pressure relief valve, or a cracked tank, and figuring out which one it is determines whether the fix is a simple part swap or a full replacement.
Sediment and mineral buildup are among the most common reasons a water heater underperforms, especially where the water supply runs harder. Minerals settle at the bottom of the tank over time, insulating the burner or heating element from the water above it and forcing the unit to work harder just to reach temperature. This is a major contributor to hard water buildup affecting home plumbing systems, and left unaddressed, it can shorten a water heater’s lifespan by years. Flushing the tank and checking the anode rod during a service visit usually resolves it before a replacement becomes necessary.
Thermostat and heating element failures typically show up as lukewarm water or water that never gets hot at all. These parts are straightforward to test and, in most cases, straightforward to replace.
Pilot light and ignition problems affect gas units specifically and can stem from a dirty sensor, a failing thermocouple, or a gas supply issue that needs a trained eye to diagnose safely.
Tank corrosion and rust are often the deciding factor between repair and replacement. Surface rust on fittings can usually be repaired, but rust coming from inside the tank itself is a sign the unit is nearing the end of its life.
