"I did have Davis & Son repair my Heating system and they did a very good job. When I called to have them install a gas line (about 10 feet), they were going to get back to me with a quote and timeline. That was a month ago - nothing. I called and had another firm complete the work in 3 hours. Disappointed that they never called back."

"Holiday repair of leaking water pipe after hours with a house full of company! Repairman also suggested we add some support to long pipe runs to reduce opportunities for joint leaks during times when many people putting stress on the system. Relieved to have the problem fixed! (Another plumber we called returned our call the next morning...🙄)"

FAQs for water heater repair or service projects in Diamond, MO

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.
