"The original job was performed to my satisfaction, and I rushed to Judgement to give a favorable review! After that I had an issue a few weeks later and just kept ignoring my calls and texts. I tried 10 days ago to reach out about a Non-Emergency pin hole leak and Craig asked when I am available and I gave him a 7 day schedule because I had 2 doctors appointments last week but I am a retired senior so my schedule is 90% free and STILL NO ANSWER! I then reached out to his associate Alex who ALSO IGNORED MY TEXTS! NEVER DO BUSINESS WITH THIS CLOWN ORGANIZATION AND CRAIG IS A TOTAL FLAKE WHO ALL OVER THE PLACE AND 1,000% UNRELIABLE!!!!!!!!!!!!

FAQs for water heater repair or service projects in Oyster Bay, 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.
