"Finding a reliable contractor is tough these days, but I got lucky hiring Chris. He and his son arrived on time, replaced my electric hot water tank, fixed a leaking guest bathroom sink, and cleaned up afterwards. Chris is a true professional with a great attitude excellent work at a fair price. I highly recommend him."

"Mike was excellent. He came in was very polite and professional. He quickly provided the quote and in less than an hour had removed the old leaky faucet and installed the new one. It worked perfectly and looks amazing in the kitchen. Mike removed all the old parts and new faucet packaging. He even gave me pointers on diy checking water pressure to make sure there is not too much pressure coming in. Also, reminded me to register my Delta faucet which I did shortly after. Thank you Mike!! Price seemed a bit high, but it was done right away on a Saturday! With 6 month warranty on the plumbing work."

FAQs for water heater repair or service projects in Old Greenwich, CT

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.
