" ⭐⭐⭐⭐⭐ Water Heater SOS was a lifesaver! When our water heater broke down, they responded quickly, diagnosed the issue, and had it fixed the same day. The technician was professional, knowledgeable, and took the time to explain everything clearly. Pricing was fair, and the service was top-notch. I highly recommend Water Heater SOS for anyone needing fast, reliable water heater repairs!"

"Dennis installed a new 75 gallon water heater and circulation pump in our home. His price was very competitive and lower than several other bids we got. He communicated with us well throughout the entire process. He worked around our schedule and the installation took only a couple of hours. The new water heater is working perfectly. I highly recommend Dennis and USA Water Heaters."

"Our sixteen year old water heater was leaking gas. My husband called The Water Heater Company who quoted for exactly what repairs were needed. The telephone representative who helped us requested photos of the water heater. He could tell what items were needed to bring the new water heater up to code. We were very pleased that Tony, the water heater installer, was scheduled to come the next day! Tony was punctual, thorough and answered all the questions I had. He explained everything that was done and made suggestions for other improvements we might want to have done. Everyone was very professional and very honest from beginning to end. They also use the very best water heaters with great warranties. Much higher quality than you can get at Home Depot or Lowes. We are very excited to recommend Tony and The Water Heater Company!"

"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."

"I was hoping to get a tankless water heater installed to replace my old tank heater. Phill's staff gave me a thorough itemized estimate, which unfortunately revealed that it would be too expensive to convert to tankless (mainly due to the cost of running a much larger gas line over to where the water heater is), so I had them do a straight-up replacement of my tank water heater. They were prompt and left a clean area behind."

"Your guys CJ & Andrew were awesome! They did such a nice clean looking job! Super professional and very informative. They walked me through setting up the app for the whole house water shut off valve they installed and now I get a reduced rate on my homeowners insurance. They also found that my water pressure reducing valve had failed and replaced that at the same time. Couldn’t be more happy with the job they did."

FAQs for water heater repair or service projects in Mission Viejo, 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.
