Common Water Heater Repair Problems in Sunnyvale
No hot water at all
A failed heating element, pilot light issue, or thermostat failure. We'll diagnose and restore hot water same day.
Water not hot enough
Sediment buildup, a failing dip tube, or thermostat issue can reduce temperature. We'll restore proper heating.
Water heater leaking
Tank corrosion, loose fittings, or a faulty T&P valve can cause leaks. We provide leak repair and replacement guidance.
Popping or rumbling noises
Sediment buildup at the bottom of the tank causes these sounds. We'll flush the tank and inspect for damage.
Tankless water heater error codes
Flow sensor, ignition, or venting issues trigger error codes. We're experienced with all major tankless brands.
Pilot light won't stay lit
A failing thermocouple, gas valve issue, or draft problem. We'll repair the ignition system for reliable operation.
