Most repairs cost $100–$400. Common fixes include thermocouple replacement ($150–$300), heating element replacement ($150–$350), and T&P valve replacement ($100–$250). A tank leak, however, means replacement is needed.
For gas units, check the pilot light — a failed thermocouple is the most common cause. For electric units, a tripped breaker or burned-out heating element is likely. Both are repairable for $150–$350.
Popping, rumbling, or banging is caused by hardened sediment at the bottom of the tank. A professional flush ($100–$200) usually resolves it. If the unit is 10+ years old, the sediment may have caused permanent damage.
Usually not. If the repair costs more than half the price of a new water heater, replacement is the better investment. A 10-year-old unit is near end-of-life and likely to need more repairs soon.
It depends on where the leak is. A leaky valve or fitting can be tightened or replaced for $100–$250. A leak from the tank itself means internal corrosion — that's not repairable and requires full replacement.
Most repairs in the Bellevue area can be scheduled same-day or next-day. For emergencies (flooding, gas smell, no hot water with an infant), plumbers offer priority response.
You can, but most homeowners prefer a professional flush ($100–$200). Improper flushing can stir up sediment and clog the drain valve. A plumber also inspects the anode rod and T&P valve during the visit.
