"GREAT. They replaced our very old dead boiler with a brand new state of the art boiler/tankless hot water heater combination and also got a very reasonable monthly payment plan AND they provided the forms for rebates."

"They showed up promptly and provided an estimate which I accepted, but it was mostly downhill from there. The technician appeared to repair the faucet leak, but after leaving, I tested on my own and determined that the leak was still there albeit to a lesser extent. I called and the dispatcher sent the technician back. He arrived with all new parts, the re-installment was a success, however, upon re-testing, he used an excessive amount of water that backed up into my dishwasher and proceeded to spill onto my kitchen floor and make a considerable mess. While the fee charged was reasonable, I would advise that you get what you pay for. Based on my experience, I would avoid this company in the future."

"Cellino did an excellent job. After calling five plumbers to fix a shower head spewing hot water and none of them could come for 4-5 days. I got hold of Cellino who came in a few hours and corrected the problem. The tech was very knowledgeable and had the job done in no time. Excellent job and of course 5 stars. Had I waited I probably would have had a lot of damage to my bathroom. "

FAQs for water heater repair or service projects in Tonawanda, NY

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.
