Water Heater Problems We Repair in Sterling
Tank heaters fail in a vocabulary of about a dozen complaints. These are the ones Sterling calls about, translated.
No hot water at all
Electric: a tripped breaker, failed upper element, or dead thermostat. Gas: an extinguished pilot with a failed thermocouple, a bad igniter, or a closed gas control. Total loss usually traces to one component, not the whole heater.
Hot water runs out too fast
The lower element burned out under sediment, a dip tube cracked so cold water short-circuits the tank, or demand simply outgrew a tank sized for a smaller household. Three causes, three different fixes.
Rumbling, popping, kettle sounds
Sediment on the tank bottom flashes water to steam in pockets — the tank is asking for a flush, and the burner or elements are working overtime until it gets one.
Water too hot, then cold, then hot
Thermostats disagreeing with reality, or a failing gas control valve. Temperature swings are a control problem, and on the scalding side, a safety problem worth prompt attention.
Rusty or discolored hot water only
If cold runs clear and hot runs rusty, the tank interior or a spent anode rod is the source. This is the tank beginning to testify about its own condition.
Leak at the relief valve or drain valve
Valves weep from age, scale on their seats, or — for the relief valve — genuine excess pressure or temperature that must be understood, not just plugged. Safety hardware gets diagnosed, not silenced.
Pilot will not stay lit
Thermocouple wear, a dirty burner, weak draft, or a gas control at end-of-life. Each has a test; guesswork has no place around gas appliances.
Sulfur or rotten-egg smell in hot water
Bacteria reacting with the anode rod in a warm tank can scent the hot water. Flushing and anode strategy address it — a fixable nuisance, not a failing tank.
