Customers say: Quality work

"We are incredibly grateful to Pedro Galvan and his team for stepping in during a moment of urgent need. When our hot water system suddenly failed, leaving us without hot water for daily essentials, Pedro responded with a level of professionalism, clarity, and compassion that is truly rare. From the very first call, Pedro was attentive, transparent about pricing, and committed to solving the problem quickly. He provided us with the most cost-effective and honest quote out of several we obtained—and, even more importantly, was able to come almost immediately when others could not. His workmanship was precise, efficient, and tidy. It was clear we were in the hands of someone who genuinely takes pride in his craft. In a world where so many service professionals overpromise and underdeliver, Pedro Galvan delivers exactly what he promises—and does so with warmth, integrity, and a deep respect for his clients. We recommend him without hesitation to anyone needing plumbing services."

"Gabriel charged us ridiculous prices for simple tasks ($75 for replacing a valve faucet in the backyard and $200 for replacing an older bathtub drain with one that we bought) on top of the $300 (150/hour labor) that he took just to show up and diagnose a potential leak. He initially said that the $200 included work on a second drain that was very corroded and stuck and promise that he will come again since he was missing a tool but when he show up he asked for an additional $300 at which point we almost let him do it but he requested the money beforehand since he was worried (rightfully) that if he breaks the tub we will not be paying him. At which point we decided to not let him do the job since he does not put his money on his skill. We managed to fix the second drain with $20 given to another plumber who came in for an unrelated issue."

Customers say: Quick response

"I had an awful experience with Cupertino Plumbing. The plumber showed up, barely stayed for 15 seconds, and immediately started swearing at me, saying he didn?t care about the job. Completely unprofessional and disrespectful. If this is how they treat customers, I would never recommend them to anyone."

"The crew from Albert Nahman did a great job from start to finish. The project was to replace the original ductwork in our 60 year old house. Tom provided excellent advice for the estimate then Bryan’s crew did the job, 2 days, within a week of my acceptance of the proposal. Great work."

"We've been working with Mike Counsil for over 8 years - clogged drains, water heater, new toilets, and most recently a sewer re-pipe. Yes, they may be more expensive than other companies, but with Mike Counsil you get what you pay for - quality work. A big shout out to Rudy and the whole team - they are hardworking, reliable and courteous."

FAQs for water heater repair or service projects in Alviso, 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.
