"I had a tankless water heater installed but needed the gas line to be dug from the other side of the house for it to be connected. The job was complicated but Luke and his crew from Mr. Rooter did a great job! I would totally hire them again for any plumbing needs."

"SMK plumbing did a great job for me with a whole house water re-plumbing & main water line from the street. The team was efficient, professional, and polite. Job was started and completed in one day. They even moved the whole house shut off and pressure valve to a very easy to get to location."

"This will be a long review but these gentlemen Robert & Ian are absolutely worth it! On Friday morning, my gas water heater sprung a leak at the bottom and needed to be replaced. I called the Oak Ridge Gas Co (ORUD) and they said they couldnâ t come until Monday. 7 people (6 girls & me) with no hot water for 4 days! Next I called some local plumbers. One by one they said either theyâ d come around 6pm or they didnâ t handle gas units. Iâ m glad they were busy but I needed someone now! Next I called 2 major companies that are well known in the Knoxville area. One came, gave a 3 minute look and quoted a mid 4 figure price TO REPLACE A WATER HEATER! The next on the scene was Robert Mason & Ian (I donâ t know his last name) from TENNESSEE STANDARD PLUMBING & DRAIN. These gentlemen took their time. They asked many questions, they did a very thorough and professional inspection. They were straightforward, honest, neat and genuinely concerned about providing service, not just doing a job. While speaking with Ian, he was sharing about how much the leadership in the company truly cared about their employees and showed them tremendous respect. I found that to not only be reassuring but also experienced how that translated to how they genuinely cared about my family. The inspection took a good deal of time. They went into the crawlspace and really did a full inspection. Remember, this is Friday afternoon on Fatherâ s day weekend. When they were done, Robert showed me his findings. For those that donâ t know, many of the houses in Oak Ridge were built in 1943 so most of my plumbing is 80 years old. Robert showed me the pictures of the main pipe coming out of the ground into the house. Only God knows how it had not blown out yet, it was that corroded. Let me stop here and say that Robert & Ian were the only ones to do this inspection. Had I just replaced the water heater, the pressure* (more on this later) would have blown somewhere else and potentially taken out the furnace with the water. About the water pressure, they were also the only ones to measure the water pressure which was 100 psi when it should be half that. They also noticed that I did not have a pressure regulator or a main shut off. Important things to have in 2024 that perhaps werenâ t in 1943. When they entered the house they had special shoes for neatness and respect which was nice. Finally when they were completely done, we sat down and they presented 3 different options which we discussed in detail. There was absolutely no pressure, no sales talk, nothing except honest information and options. There is a very true saying that you get what you pay for. Tennessee Standard Plumbing & Drain is not the cheapest but there is also a difference between â costâ and â priceâ The â costâ over time will be less because they use top of the line material and they perform exemplary work which they stand behind. It turned out that none of the 3 options were attainable so Robert worked within our budget to get the vital items fixed. They handled everything. They called to get the ground marked, they dug up only the area they needed to and they put it back as best you can when you trench a yard. Another professional thing was that they were prepared. They had what they needed on the truck with them. There was no wasted time while they went to get whatever was needed. I greatly appreciated that. In the end, we decided on a 3 visit plan. They did the emergency items this visit. In 6 months or so, they will return for the 2nd phase and the final mostly cosmetic phase where my wife gets the bathroom she really wants. I would highly recommend these gentlemen and Tennessee Standard Plumbing & Drain!"

"We had a wonderful experience with Plumbing Services. We were contacted immediately and responded to promptly. We scheduled our service and the job started on schedule. The service was very thorough and we appreciated the owner taking the time to explain the process and advise us on good preventative maintenance measures. We are were very satisfied with the work and discussed a future service call. We were very appreciative of of his suggestions for the future project. Below, the review asks for the price of the job and it is listed. I think it is worth noting to consider the company’s drive time to us as well as the multiple jobs performed. It was a near two hour drive to get to our home for the company and the price is reflected. Overall, we would and do plan to work with this company again."

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