Customer Case: A Kitchen Sink That Wouldn’t Let Go

A homeowner in Tellico Plains began noticing that water lingered in the kitchen sink long after the dishes had been rinsed—and sometimes it even backed up entirely. Frustrated by persistent clogs and slow draining, they reached out for professional help.

How it was solved:
A HEP technician inspected both under the sink and out in the crawl space. He discovered that sections of the old drain line were sagging, causing so-called “bellies” where debris and water pooled. The team removed about 40 feet of the faulty pipe and installed a new, properly pitched PVC drain run. Under the sink, they fitted a modern waste tee with a dishwasher hookup, added a P-trap and an air-admittance valve to keep odors out, and secured the line with straps. The result was a smooth, reliable drain that no longer traps water.

1. Watch How Quickly Water Drains

If your sink or appliance takes a minute or more to clear water away, that’s your cue to investigate. Slow draining often points to a partial blockage or a plumbing run that isn’t pitched correctly.

Early signs: Gurgling sounds, water backing up into the dishwasher, or an unusual odor.
Quick check: Pour a pot of water down the drain—if it pools or trickles out, call an expert.

2. Proper Slope Keeps Water Moving

A gentle downward angle (about 1/4 inch per foot) is key. Too flat, and solids accumulate; too steep, and water can outrun debris, leading to clogs further downstream.

DIY tip: When replacing a section of PVC pipe, use a level and measure the drop between joints.
Pro insight: HEP technicians use special fittings and strapping to maintain that exact slope even over long runs.

3. Add an Air-Admittance Valve for Odor Control

Vent pipes can be tricky to retrofit in existing cabinets. An air-admittance valve (AAV) lets fresh air in to balance pressure without allowing sewer gasses back into your home.

Why it helps: Prevents gurgling and suction issues that can pull water out of the P-trap.
Where to install: Directly under the sink, on the vertical tailpiece, away from heat and moisture.

4. Routine Maintenance to Keep Issues at Bay

Flush drains monthly with hot water and a mild vinegar solution.
Avoid dumping grease or large food scraps down the sink.
Keep accessible shut-off valves clear and labeled.
