"I live in Tellico Village and we were having issues with slow flushing and bubbling sound in the drains. I called WhizPro to come out. Online and on the phone I was told it is a $99 service fee to come out. That quickly changed $420 because it is considered ?complex? after he noted water in the sewer clean out pipe. The plumber mentioned it could be a problem with my grinder pump. I told him that the POA maintains that, and I would need to call them if this is the issue. He unsealed the basin lid and noted it to be full, indicating a malfunction. I went inside to call the POA Water Works. Meanwhile, he opened the electrical box for the grinder, which he later told me he is not supposed to do. He ran a voltage test and told me my grinder was ?burned out?. I told him the POA water works is coming, and they will manage the job from this point. He declined to reduce the $420 fee to $99 despite only taking off two lids. Would not recommend. "

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.
