"This was the second time using South Shore Plumbing & Heating they installed a tankless water heater for me in March. 2020 and today Nick located and fixed a pin hole pipe leak under my house cement slab. From the time Nick started to make his first cut in my Sheetrock he used a level to make sure he was cutting a straight line ( thatâ s a professional who take pride in his work) when he drilled to open up my slab he made a small hole that was right where the pipe leak was. Cut out the bad pipe and installed new section of pipe no leaks and Nick re- cemented the hole closed and clean up all the debris. Anyone who needs excellent plumbing or heating call South Shore Plumbing and Heating ."

FAQs for water heater repair or service projects in Sag Harbor, 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.
