"Excellent communication from Keith; outstanding service from Roger. Professional, timely, and reasonably priced. They came in under estimate on my boiler repair and advised that a second bit of work that had previously been discussed was not going to be necessary. I will definitely use them again and highly recommend them!"

"I had a great experience with this plumber! He arrived right on time and was very professional and friendly from the start. I had a leak in the plumbing in the wall between the bathroom and the bedroom and he took the time to explain exactly was going on. He even went under the house (in the cold and dark) to inspect the issue further and took pictures so I could clearly see the problem myself. He explained the repair in a way that was easy to understand and fixed the leak quickly ad professionally. I really appreciated his honestly, communication and the quality of his work. Everything is working perfectly now! I definitely would recommend him and would happily call and refer him if I ever need a plumber's help!!"

"We were very pleased with the communication and the outcome of our project. We have an old home with some older piping. Finding someone that works on steam boilers is tough. When they looked at the install, they explained what needed to happen clearly deand unrstandable."

FAQs for water heater repair or service projects in Northwood, NH

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.
