"Robert Johnson was so helpful in discussing the h/w heater installing and the venting requirements. His price was so much better than others companies in the area. His crew for the actual install was as also great! Kevin, the crew leader, explained how everything works and the cleanup was perfect!"

"Exchanged messages with Mike to describe work needed, replace an outdoor faucet and shutoff value (previous faucet was leaking). He gave an estimate, reviewed work to be done. Replaced outdoor spigot with a frost-proof spigot, put on new value. Quick test and validation. Professional, efficient and happy with work done! Thank you Mike !"

"Christian was very knowledgeable about our water heater and explained everything as he went along testing different issues that might be causing the problem. He was professional and gave me several helpful tips on upkeep of my Rinnai that 2 other companies that had serviced the unit over the years had not bothered to mention. i absolutely would recommend Walley to anyone needing HVAC work."

FAQs for water heater repair or service projects in New Boston, 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.
