"Did a $59 consult only. Turned out the cost of repairing the old heater was almost as much as a new one, so we got a new one, and handled the install ourselves. Luis B was great, knowledgeable, friendly, didn't try to upcharge just to sell a heater, which we appreciated. Gave us an honest evaluation, several options, and was right on time. I will say, though, that the company failed to call me when he was on his way... not a big deal. All in all a good experience."

"My family recently moved Fresno. When we lived in LA we hired Johns Plumbing to install a new water heater. It was 40 gallon Bradford White water heater. John gave a free estimate first. Then his team installed water heater. Victor and his helper worked fast and accurate. We highly recomend Johns plumbing"

"Stop looking for a plumber! Sam is the man for you job. I can’t say enough about him and his team. He worked within our budget, did top notch service, and even offered free advice for our other bathroom. Sam installed a tankless hot water heater, ran plumbing out to a brand new Adu, and helped us complete a perfect compact bathroom. Sam is a master of his craft and priced well. Thanks again Sam!!!"

"Authority came out to service my tankless water heater, and I?m really impressed with the experience. Chris was the technician who handled everything, and he made sure to explain how the system works and what needed to be done. He performed a thorough cleaning, checked all the components, and made sure everything was running efficiently. He was professional, knowledgeable, and took the time to answer all my questions. My water heater is running like new again! I?m very happy with the service and will definitely call them again for any future needs. Highly recommend!"

FAQs for water heater repair or service projects in South Pasadena, 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.
