"My Remedy Plumber arrived on time and didn’t really charge me for his service because he stated what he needed to do may not fix my problem because I needed a new faucet which he did not have. Water was running from both the tub’s faucet and the shower head. After pulling off the faucet and making a minor adjustment to a washer within the faucet the problem was "temporary" fixed, the washer was damaged. He stated that a new faucet was needed and that I could call back to have that installed. I thanked him, gave him a small thank you gift, and he was on his way. I was thankful that this plumber had "integrity" and did not try to overcharge me for work that did not fix my problem. I would surly hire this company again!!"

"Mr. Brian Langford made all the arrangements with the installation of our gas hot water heater from Lowe's via McCarthy plumbing. He was extremely helpful,patient, professional and available to answer all questions. Due to his approach to his work, we will be working with both companies in the future. Only concern I have is the warranty between Lowe's and AO Smith Hot water heaters. Once the heater is installed, Lowe's severs ties. If there is a problem with the hot water heater, you cannot return it to Lowe's although it was purchased through them, this is clearly stated on the Hot water heater in bold writing."

"Just started working with Markool this summer and they have been fantastic! When I need service, they are so fast and every person we have interacted with has been polite, knowledgeable and personable. We unexpectedly needed to replace our system during a heat wave and they were super. So responsive and quick. I would highly recommend Markool for all of your HVAC needs!"

"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"

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