Plumbing for restaurants and food service
Grease is the biggest plumbing problem in food service. In Knoxville, KUB’s Grease Control Program requires commercial facilities that cook, prepare or serve food to have grease control equipment, with the type and size set by KUB after a permit application.
KUB requires a gravity grease interceptor, typically holding 1,500 or 2,000 gallons, at any food service facility with automated dishwashing equipment. Smaller grease traps typically hold 20 to 100 gallons. A plumber can clear grease-clogged kitchen lines, repair traps and fixtures, and jet lines that keep blocking.
For drain blockages, see drain cleaning and hydro jetting.
Plumbing for apartments and rental properties
Landlords and property managers can use one number, 865-321-8269, for every property. A licensed local plumber can handle tenant repair calls, water heaters, leaks, clogs and turnover work across Knoxville and the surrounding counties.
Tell us the property address, which unit is affected, and how to reach the tenant. For leaks between units, see leak detection.
Do businesses in Knoxville need backflow testing?
Most do. KUB says most businesses need a backflow device, including restaurants, car washes, hospitals and salons, and that devices must be tested annually, after installation and after any repairs.
Testing is done by state-certified, KUB-approved backflow testers, who send passing results to KUB. KUB states it must terminate water service to customers who do not install, maintain and test their device. Homes with lawn irrigation, pools, fire sprinklers or wells may need a device too.
If you're served by a different water utility, it will have its own cross-connection rules, and your plumber will confirm them.
