"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."

"Isaac and team were incredible in getting a bunch of updating old and out-of-code plumbing work done on our tricky 100-year-old house. They took time to really dig in and assess the right game plan to make sure not only that all the plumbing and vents were done properly, but that they looked great given some would still be exposed / visible under our porch. The team was communicative and courteous. Our new plumbing is working like a charm. The tankless heater and smart shutoff are cranking. And everything passed on first inspection. The inspector even commented how clean and detailed it all looked. Would recommend SplashFix for any project, big or small."

"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."

"Got a note from SFPUC for massive water use for the past several days, but no clear smoking gun. Was really worried and called Francisco asking for immediate help. He was at my house in 15 minutes and walked through all the most common culprits (toilets, etc), until we heard the water running outside and found that my kids had left the hose running. Paid him for his time and will definitely be calling him the future - amazing service. Kids learned a good lesson too."

"JPC team did an excellent, professional job on our storm water sump pumps related project. (Two sump pumps were working; they did not need repairs.) 1) Cut and replaced two broken pipes; installed new valves 2) New float sensors installed and set to auto-start the sump pumps 3) long outflow pine, connecting to city's water drainage system, was cleaned using long snake and high pressure water pump combination. 4) successful final test with water filled in water chamber and sump pumps working 5) JPC gave warranty for work done and signed up for once-a-year annual maintenance visit in October."

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