"What a great guy! The furnace and the water heater went out at the same time. I was freezing! It was all sorted out the same day. Angel was able to remove my old water heater with a new one. I plan on hiring him again, Thanks, youâ re an Angel!"

"I had plumbing leaks in a couple of places, but the men that did the work went above and beyond by replacing every component involved top to bottom to ensure there would be no leaks for a long time to come. Very satisfied with the quality of work as well as how quickly it was done."

"Michael is hands down the best I’ve ever worked with. He’s exactly who you wish the folks working on your home are like. He has an amazing attention to detail, meticulous, and puts safety above all else. When he realized my boiler couldn’t be put in just yet because of further water damage, he had a water remediation company come in TWO hours to instantly start the process. When he realized my hoses needed updating, he made sure to call it to my attention and had them switched out. For work outside of his scope, he still makes sure to let you know what’s the best for future proofing your home. Above all, he’s communicative, on time, honest, and always there when I have a question. Plus, you can tell he really cares about his craft, and that translates to the job. He chooses the best solution for your situation. My only complaint is I wish he did literally everything else outside of plumbing! I’d want a Michael version of a carpenter, electrician, every day handyman. He‘s that good! "

FAQs for water heater repair or service projects in Watertown, MA

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.
