"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."

"Doug was great. He arrived first thing Monday morning, removed the old water heater and had the new tankless system installed and ready to go by early afternoon. I appreciated the information he provided and how easy he was to work with. He did a quality job and I would not hesitate to contact him again for other people plumbing needs."

"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."

"David replaced my upstairs copper piping with PEX because I was having leaks in July of last year. He did a good job and had a good drywall repair man fix the drywall cutouts he had to make to access the pipes. He also advised me to have the PEX tubing in my crawlspace insulated, which I agreed. His pricing overall I thought was fair and would recommend him, however, last October I had occasion to go down to my crawl space and found that only half or less of the PEX tubing had been insulated. I informed David about this and he said he had since fired the two men whom he had assigned to do the job because of poor work habits and assured me he would come back and finish insulating the remaining tubing. I did not hear from him after that and so in April I contacted him by messaging, but he did not respond, nor again after trying to contact him again last month. I am now wondering if he is still in business here."

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