"Chris replaced gas water heater, re-plumbed washing machine discharge, replaced all sink water supply valves and hoses in home and apartment. He was completely professional, on time, very good communication and did an excellent job for a fair price. I would definitely use him exclusively and I have already recommended him to others"

"For my central A/C install. Varsity is the gold standard for professional service. Varsity works as a team who patiently brought me through the process from start to finish. I'm extremely satisfied with with the results, I will always have Varsity for my home services. Varsity earlier this year installed a walk in shower for me. The results were fantastic. In the future I will have Varsity install a hot water heater."

"I had A&M service my On Demand hot water heater. He did a great job. I decided to have additional work done. I have an older home and decided to have some old valves and pipes replaced. I would definitely recommend A&M"

"Kevin was great! The rest of the company not so much. Kevin diagnosed the problem immediately as the thermostat, had a replacement in the truck, and completed the installation of the new unit quickly. He showed me how to program the updated version, and everything seemed to be fine - until the next morning. Turned out the replacement was defective. When I called, I was told that they might not be able to get back to me that day, but Kevin interrupted his schedule to come back and put in a new (and working) unit at no charge."

"Great service! He came in, gave good estimate on replacing our whole system. I was also doing some remodeling and he was able to work around that, worked on time. Never had a problem, the only time he's had to come back was when I had more work for him. Pricing is reasonable."

"We contacted Berardi Electricals through Angi, and Leo reached out to us right away.Leo came to our house within an hour, quickly identified the issue as water damage to the main electrical box, and explained that it was an emergency situation. He returned the following week, exactly as discussed, despite bad weather, and efficiently moved the box, repaired the wiring, and provided temporary electricity until the next day. His work was exceptionally clean, efficient, and thorough, and he took the time to give us the right advice, possibly saving us from an electrical fire. We found him to be honest, knowledgeable, and true to his word. We would highly recommend Berardi Electricals to anyone looking for a trustworthy electrical work."

FAQs for water heater repair or service projects in East Setauket, 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.
