"This was a last second thing. Our hot water heater died on us. Left him a message on Tuesday afternoon. He showed up first thing next morning. Right on time. Discussed the job and he gave me a estimate with a small window. And he said he could have me back with hot water in a few hours. Sure enough less then 3 hours later I’m back running. Very good and clean job. Very professional with all aspects of the job which was nice. Best part of it all when it’s time to pay his his price was barely over the low end of his estimate. Everyone else would most likely been barely under the top end of their estimate. So a very good clean job done as a rush for a good price."

"Recently used Mahon Plumbing for various plumbing needs around my house. As a new homeowner you can be skeptical on what’s behind your walls or in this case pipes. Mahon did an initial sewer line inspection and called them back to swap out toilets and install natural gas in my backyard for a grill and fire table. They were professional, honest, and extremely knowledgeable about all phases of my projects. I would recommend Mahon Plumbing for all of your plumbing needs!"

Small jobs welcome

"I hired a plumber through HomeAdvisor using prepay but I would not recommend this service. The contractor left a leaky pipe that caused water coming up through carpet. I had to purchase a wet vacuum to dry out the carpet. I had to contact HomeAdvisor again and hired Dave the Plumber, LLC who had to redo the installation done previously. Dave the Plumber replaced all the piping and outside spigot because of a water leak the previous contractor left. Thank you Dave the Plumber for being a professional and a job well done."

"My water heater started leaking on a Sunday. I reached out to Family Fire Service and they responded immediately. They had a new water heater out to my house the next day and installed in a few hours. The supervisor and the tech worked seamlessly to have us up and running. They provided quality service and at a very competitive price. I highly recommend Family Fire Service and Plumbing. KC"

"The price was part of my check up I got. I just like that they seemed to want to talk me into having my air conditioning cleaned and it only been out there like 6 months. My interaction with them was fine. I told them no and so be it. The work turned out fine. They were fine."

Customers say: Quality work

"Rob O'Donnell came in clutch for us when we found ourselves in a pinch doing a job out of our normal service area for a customer who had water damage to their home. It was after 4:00pm on a Friday afternoon and we needed to find someone to disconnect a gas stove so we could finish installation on Saturday. Needless to say, we were having trouble finding anyone who could help us out with such short notice. After leaving a message with O'Donnell's Plumbing we got a call shortly thereafter from Rob, who was willing to go out on Saturday morning to disconnect the gas line for us before another job he already had scheduled for the day. He also returned very promptly to get everything hooked back up. -- furthermore he was able to send an invoice by email and we were able to pay electronically! Very convenient and also eliminated the need to bother with mailing a check. -- Highly recommend O'Donnell's Plumbing!"

FAQs for water heater repair or service projects in Frederick, 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.
