Water Heater Repair FAQs — Castro Valley, CA

Why do I have no hot water in my Castro Valley home?

Common causes are a pilot or ignition failure, a bad thermocouple, a tripped breaker or failed element, or a gas valve problem. We diagnose it on the spot.

Is it worth repairing an old water heater?

If the tank isn't leaking and is under about ten years old, repair often makes sense. A leaking tank should be replaced.

Why is my water heater making noise?

Popping or rumbling usually means sediment has built up in the bottom of the tank. Hard water in many California areas speeds this up.

Do you repair tankless water heaters too?

Yes — we service and descale tankless units as well.
