Other companies are calling me all day on Monday to offer to start quotation process, while I had a new water heater installed by lunch time on Monday. Quick, clean and professional service and competitive price."

"Totally excellent service. My furnace was not working so I had no hot water. I called after 7 pm and Mike was there first thing in the morning to check it out. He located the problem and took immediate action to resolve it. Called suppliers, located the part for a 57 year old furnace. The following day Jason and Chase came and made the repair. Cost effective price with professional workmanship. Reliable and trustworthy."

"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!!"

FAQs for water heater repair or service projects in Bow, 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.
