"David and Eli at First Class were knowledgeable and personable. David responded in five minutes on a Sunday and came out the next morning. They would have charged $1300 less than the other bid for a 50 gallon heater but we chose a Navien point of source to save money on PGE gas bills. That cost $3900 July 2025-beware tariff price increases - which was half and less than competitors. "

"Spent too much time discussing a replacement faucet. Did schedule very quickly which was appreciated, did do the work requested quickly after “discussion “ stopped. I do feel that the “come on” $49 work estimate fee gets you involved with them when you have no idea that the cost would be so much! This I find is the norm with plumbers on Angi. Total cost for a simple procedure( yes I could not do myself) was at least 50% more than I thought."

FAQs for water heater repair or service projects in Castro Valley, CA

Warning signs include fluctuating water temperatures, a pilot light that repeatedly goes out, unusual noises from the tank, or complete heating failure. You might also detect a rotten egg smell, indicating a potential gas leak, or notice water that never reaches the proper temperature. If your water heater is over eight years old and displaying these symptoms, the gas valve is a likely culprit. Professional inspection is recommended, especially if gas odors are present.

Water heater gas valves are not universally interchangeable. Each valve must match your specific water heater's make, model, and specifications. Important compatibility factors include gas type (natural gas vs. propane), BTU rating, connection types, and physical dimensions. Using an incorrect valve can result in poor performance, premature failure, or dangerous gas leaks. Always consult your water heater's documentation or a professional plumber to identify the appropriate replacement valve for your unit.
