"Steve with Maverick Water Heaters came out to my home several times to try and repair my very old (obsolete) tankless water heater. He was very friendly and professional and did everything possible to try and repair the heater before recommending a replacement. Once it was determined that a new heater was needed, he ordered it and then came to my home immediately to do the installation once the heater was available. He completed the job in a timely manner and we were very happy with his service."

"We are very pleased to have found Steve and his cute pup Sam. Steve was very knowledgeable and had a very nice, trustworthy demeanor. He went over our options to either repair or replace our water heater. Clearly stating the pros and cons of both choices. We chose to replace our water heater, and he had the job finished in 1.5 hours ! I would definitely hire him again."

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."

FAQs for water heater repair or service projects in South 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.
