Common Water Heaters Problems
View All →Leaking Water Heater
Water around the base demands immediate attention -- floor damage, mold, electrical hazards. Could be loose fittings, a failing T&P valve, a bad drain valve, or a rusted-through tank that needs replacement.
No Hot Water
No hot water from any fixture? Cause depends on gas vs. electric. Common culprits: pilot light out, tripped breaker, failed element, faulty thermostat or gas valve.
Pilot Light Won't Stay Lit
Lights but will not stay lit? Almost always the thermocouple -- a safety sensor that detects the pilot flame. When it fails, the gas valve shuts off. Straightforward DIY repair, under $25.
