"Clarence was very quick and efficient to get our hot water tank replaced and we were so satisfied with his work and price on the hot water tank that we had him return to install our dishwasher when we upgraded our kitchen appliances."

"Amazing experience!! The owner Brandon is very knowledgeable and has a very well trained team that does great work. I had a water line break under my driveway and within two days of Brandon coming to give me an estimate it was fixed like it never happened. Highly recommend A&P plumbing to everyone I talk to."

"Seems like every summer for the past 5-6 years we've had issues with our AC. The companies we've had work on them have only provided a solution for each year. This time we contacted Wilson Mechanical Services through Home Advisor. They spent 3 hours repairing our system probably the way it should have been repaired instead of just enough to get by. Their price was very reasonable. They also gave us a price to move our AC units to another location that is $900.00 cheaper than another company we contacted! That's a lot of money to save!! Would definitely recommend this company to anyone having AC issues!!"

"Diagnosis and repair required a second trip, since repairing the toilet seal didn’t work; the leak was worse than we thought. No shoe covers, so the rug was a mess when he left, but the work itself was completed efficiently and well."

FAQs for water heater repair or service projects in Charleston, WV

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.
