"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."

"My current 10-year 7-month-old water heater from Bradford White developed some issues with the control panel. The cost of repairing the control panel versus a new water heater was a no-brainer. We opted for a new water heater and the service we received from Sam R, a technician for the Water Heater Company was outstanding. He is so meticulous in getting everything done correctly. He kept the work area clean and kept me well-informed on what needed to be done as he worked. I would highly recommend this company. I included the images of the old unit in the process of being removed and the finished project."

"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."

"The gents from Burris were excellent. When I called to have them check our water heater and furnace, they were very responsive. I was concerned that they might not be able to make it out the same day as I was calling in the later part of the afternoon, but they said that they could come that day at 3:30pm. Needless to say, at 3:30 on the dot, they were pulling up to our driveway. That in itself is impressive! They greeted me courteously, didn't chitchat or waste time, but went straight to work checking on the water heater (which had gotten wet during our last big rain), and soon diagnosed the problem. The burner had water in it. Since I was not over their shoulder watching, they certainly could have said I needed a new burner assembly, a new thermocouple, valve control unit, or all three (since those got wet as well) - all of which would have made them more money in parts and labor. Instead, they dumped the water, cleaned and dried out the burner, and got us going again. They even let us know that there might be a future issue with the ignitor, but that as it dried out, it would probably work just fine (they could have just charged us to replace it when it didn't necessarily need to be). They were ethical, actually did troubleshooting to fix the problem instead of simply replacing parts, and ended up charging very reasonably for their labor. They looked at the furnace as well, said they couldn't really get to a thorough exam right away, but contacted one of their associates who could. They went above and beyond in doing so. They could easily have said they needed to come back later - thus saving the job for themselves. Instead, they got us together with someone else, even though it cost them the $$ they would have gotten by keeping that job for themselves. They showed they were more concerned with making sure the customer got what they needed instead of keeping the money and the job. THIS is how a company gets repeat business! I highly recommend Burris Brothers, and will use them again for future plumbing and heating needs."

"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."

"Would highly recommend Drain Town Rooter to anyone. May be a funky company name but they did a great job on my Tankless water heater install. Ryan was excellent and even came back after I removed the old tank box/stand, had some drywall repair and painting done, to re-route the pressure relief pipe straight down which had been routed around the old tank box. Cosmetic but much cleaner looking. I’d hire them for other plumbing jobs as well."

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.
