"David arrived in less time than estimated, immediately identified the problem for the leak, and made the repair in less than an hour even though he had to work in the crawl space and master bathroom. He was very friendly, courteous, knowledgeable, and definitely an expert."

"After having Bobby come to check out our leaking water heater, he went over options to replace, options to upgrade and how each of those could be accomplished and at what price. We had a 50 gal electric heater and my wife and I decided to replace what we had, plus add another 50 gal tank for back up. This was accomplished knowledgably and quickly, using the existing pipes, plus adding connecting pipes to the extra heater. Expansion tanks were provided for both water heaters, which is a (relatively) new requirement. Great work, quick and professional."

"Same day service, although it was a 12-hour work day for Mr. Davis. He provided a good solution for an old problem and then repaired/replaced the shower valve. His knowledge and years of experience were evident and his prices are reasonable. I will call him again if/when I have a plumbing problem."

"Overly expensive charges for replacing our water heater and water pressure regulator. Two weeks after installation my basement was flooded again and the water heater installed was the cause. When called out to fix the problem the tech flooded my basement again on the repair. The installer and assistant were nice people and he was the plumber who came to repair it. The owner is a good guy whom I had used once prior on a small job and I really liked him. I was not pleased with his demeanor this time on the first installation or the text showing him pictures of the rupture. I would not have written this if I didn?t know the cost to him of the replacement water heater compared to what we paid. It was WAY over on the labor which much of was waiting for parts not on their truck. That?s not the customer?s fault."

FAQs for water heater repair or service projects in Johnson City, TN

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.
