We're known for our quality work and the integrity of our business. Our mission is to build long-term relationships with our clients, and guarantee your satisfaction.

"The plumber was prompt, professional, and completed the issue with my toilet in about 30 minutes. The downside was it was an expensive repair due to the $300 service call fee for such a quick fix. The plus was that the Plumber took off $25 as a first time customer ($275 instead of $300), but with the tank parts the total fee was $325."

"Chris was amazing. He was the first to arrive of all the contacted people. We talked about what I wanted (replace the cartridge) and he quoted me $250. That is not high to replace a cartridge. He determined that the shower knob faucet valve cartridge was probably NOT DEFECTIVE, possibly only cleaned, and I assumed the price would be lower with no new $100 part needed. He fixed it by adjusting the hiddent pressure valves, removed and cleaned the cartridge, but didn't lower the price. I'm mostly okay with it. The problem IS SOLVED, I know next time that I can probably adjust the valves myself, and he did a great job. So between the pretty-reasonable quote if it had needed all the work, the fast response, and quality work, I got my money's worth. I would recommend them and call them again for more work.."

"Contacted Mr. Rooter on a Saturday and they quickly sent Dave and his assistant. Dave diagnosed the problem, provided a couple of solutions (after discussing each with me) and once we settled on a plan-of-attack, he got right to it. Dave was great! He fixed the problem, the cost was reasonable and they cleaned up after themselves. I highly recommend Mr. Rooter. (P.S.- ask for Dave)."

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