Common Water Heater Repairs in San Rafael

Older homes and hard water can cause sediment to collect, reducing efficiency and causing rumbling noises.

Faulty thermostats or elements lead to inconsistent water temperature, common in aging units.
Leaking Pressure Relief Valve
A leaking T&P valve often indicates high pressure or a failing valve, requiring prompt repair.
What to Expect During a Water Heater Repair
A technician will first diagnose the issue (diagnostic fee $85–$225). For gas units, they check the burner and thermocouple; for electric, elements and thermostats. Repairs often involve replacing parts like the anode rod or valve. Permits are required for any work that alters the system, and seismic strapping must be inspected.
