"We lost our hot water late on a Friday. I called Trevor, sent him a few photos of my old equipment, and he arrived at my house an hour later, removing the old water heater and making preparations for the new installation. On Saturday morning, he arrived bright and early and installed the new water heater and made all the necessary upgrades in compliance with current building codes. Trevor was thorough, professional, conscientious, and highly skilled--and the quality of his work, from the premium parts to the final fit and finish, is truly outstanding. He did everything possible to get us back into hot water as quickly as possible, and he's easy to work with, too. Franks Water Heaters is, quite simply, the best in the business."

I could not recommend Family First any more highly!"

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