"Donald Rogerson responded very quickly, analyzed the photos I sent him, knew exactly what to bring, and provided a very reasonable quote over the phone. He reassured me from the start, and took control of the situation with the utmost professionalism and clear communication. His work was impeccable, and he even insisted on cleaning up. I heartily recommend him, not only for water heater issues, but for any indoor plumbing need. He will certainly be my plumber from now on."

"The guy who preformed the service was amazing. It was frigid in our basement because we hadn't had heat for 2-3 days and it was during the horrible snow storm here in Atlanta, and he worked quick and efficient and never complained once about how cold it was down where he was working. He even took a look at our attic vents while he was here and adjusted them to help with airflow upstairs. I would highly recommend Moncrief and will be using them again!"

"My water heater flooded my laundry room I called around and the best price I found out of 7 businesses was plumb life. I called around 11 am by 7 pm I had a new tankless water heater.

"I have had Greenlee plumbing out to the house four times, 35-year-old house. Shower valve replacement. Water heater replacement. Water Line replacement. Shower/Tub to Shower conversion: drain relocation and new shower valve. Each time they were professional, personable and reliable. More importantly is how they provided service when there was a problem. The manufacturer of the water heater had bad gas valves. There was never a safety issue, just the inconvenience of no hot water. I had two bad values. Each time I called they came out the same day and replaced the valve, now that is service. I spoke with them about the problem with the manufacturer and they advised that they manufacture was overwhelmed and could not supply all the replacement valves needed. Greenlee's solution was to buy new water heaters and remove the valve to get their customers up and running. Now that is going the extra mile! I highly recommend Greenlee Plumbing Jeffrey Coe"

"Navien Tankless Hot water heater was not putting out adequate hot water. Matthew Jones was able to troubleshoot the system, finding a valve with a bad o-ring. The valve was replaced and we have plenty of hot water now. Matt was very courteous, friendly and most of all a confident worker."

FAQs for water heater repair or service projects in Decatur, GA

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.
