"HPC quickly determined and resolved the cause for our problem in August. However, they also determined that we had a relay that needed to be replaced. They informed me that it would take some time to get the relay, I think they mentioned delays due to the tariff situation. They promised to get back to me when the relay came in. They jury-rigged the system to work properly without the damaged relay, but warned me that the jury-rig would malfunction badly if we switched from cooling to heating. Starting in November, we called HPC a half-dozen times over several weeks asking for the status of the replacement relay. We were told that the appropriate people would be informed, and that they would call us back with the requested information. On November 11th, I sent an e-mail containing the same information. This resulted in a response containing an estimate for something called a "heat kit". When I asked whether the "heat kit" contained the replacement relay, I got no response. "

FAQs for water heater repair or service projects in Potomac, MD

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.
