"Call in the morning, visit that afternoon with quote, installation next day. They didn't have our model in stock, so we got an upgrade to the next larger water heater at no additional cost. Installer was very knowledgable and friendly."

"Steve was timely and quick with replacing my water heater and was very responsive when I messaged him. He also provided great suggestions and options for my water heater replacement and streamlined the bayren rebates process for me. Provided services at a very fair price compared to other plumbing services. 10/10 would go to him for future plumbing issues."

Customers say: Super punctual

"The first visit lead to cleaning the area around the heater and burners and checking the thermocouple. Sadly that seemed to make it worse. Less than a week later No hot water for over 30 hours till the second technician replaced the thermocouple. All is perfect now. No charge for the second visit. The next step, if needed will be a tankless and their quote looks a bit steep. But I am really hoping I won’t need to go that far."

"I noticed my water heater leaking late in the evening (Saturday night), and Sunday morning I reached out to Angie's List for a water heater replacement. I set my expectations that it probably wouldn't be attended to until the work week, but Jesus for Jess Plumbing responded within minutes. Checking with some of the big box stores, Jesus had extremely reasonable pricing that included the purchase of the water heater, labor for removing/installing, and hauling away the old one. After confirming pricing, he was at my home with the new water heater in hand within the hour. Once he arrived, he had a very warm and open attitude as he broke down all the steps that we'd be going through. he was very knowledgeable with the alternate methods of electric or tankless, and gave the pros/cons should I decide for an upgrade in the future. Throughout the install, I enjoyed our conversation very much and he didn't mind that I hung out in the garage while working on other projects. He moved with the intention that only comes with years of experience, deliberate and precise. When we had to shut off the water he communicated that ahead of time knowing that my family could possibly have a need to access it. Overall the whole process went incredibly smooth and would not hesitate to hire him again or to recommend him to a friend."

FAQs for water heater repair or service projects in San Mateo, 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.
