"Talk about Top Quality service! From the professionalism of Daniel, to the great job done by Humberto and Ernest. I couldn't have had a better experience in a bad situation. They replaced our steam boiler, and our water tank and did a wonderful job. We have a warm house again thanks to them! Humberto, Ernest, I take my hat off to you!"

"We woke up to find we had no hot water. When we went down to the basement, we found the water heater had leaked most of its contents all over our basement. We immediately began cleanup and called Comfort Masters. Soon after Chris arrived and determined a new water heater was necessary. Within the next hour, the water heater was disconnected and removed. Only an hour later, Chris returned with a replacement water heater and had it installed soon after. What started as a day where we were concerned about a huge cost and days without hot water got resolved quickly for less than we thought. Chris and Comfort Masters made this possible."

"I spoke to the company owner Lou Schede on Sunday and we scheduled one of his service technicians to meet me on Monday. I informed him I would like to receive at least one hour notification prior to the person arriving for the appointment. The next day I received a text from the service technician named Kelroy. He later called me an hour in advance of arriving for the service call as Lou had committed to do. Kelroy and his helper went on to diagnose and repair the furnace issue in timely manner. I appreciate, he was making efforts to repair the furnace on this first service visit rather than replace unneeded parts or require an additional (more costly) follow up service visit."

"The two men who came to my home to replace my water heater were extremely courteous. Nick and Dylan explained all of my options to either replace or repair my unit. They performed their job with extreme proficiency and speed. The quick response from N&J Plumbing made it possible to have my hot water back within 10 hours. I highly recommend them for any of your plumbing needs."

"I cannot recommend Mark more! We called him for a dishwasher installation and pipe repair. He quoted us reasonably - and was generous with his work and time when what we thought was a simple job turned out to be much more complicated. He was absolutely a pleasure to work with - communicative about the issue and his solution, flexible with scheduling, and just an all-around nice guy. We will not be hesitating to call him in the future - our go-to-guy for all plumbing needs."

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.
