Top 5 Plumbing Problems in Knoxville, Tennessee (And How to Fix Them)

 

Plumbing issues can strike at the worst times — and in Knoxville, Tennessee, homeowners face some repeat offenders. Whether you live in Farragut, Fountain City, Halls, or downtown Knoxville, here’s what to look out for and how to handle it before it becomes expensive.


1. Clogged Drains

Clogs are one of the most common plumbing problems in Knoxville. Between food scraps, soap scum, and hair buildup, it doesn’t take much to block your drains.

Fix it: Try a natural drain cleaner (baking soda + vinegar) and avoid pouring grease down the sink. For tougher blockages, a plumber can hydrojet your pipes.


2. Leaky Faucets

A slow drip may not seem serious, but a leaky faucet in Knoxville homes can waste gallons of water daily — and raise your utility bill.

Fix it: Replace worn washers or cartridges. If the leak continues, it could be an issue with the valve seat, which may need a pro’s help.


3. Running Toilets

A running toilet can waste up to 200 gallons a day — seriously. This is especially common in older Knoxville homes with aging plumbing systems.

Fix it: Replacing the flapper or float often does the trick. If you hear constant water movement, it’s time to lift the lid and investigate.


4. Water Heater Issues

In Knoxville, mineral-heavy water can cause sediment buildup in your tank, leading to lukewarm showers or strange noises.

Fix it: Drain and flush your tank annually. If it's over 8–10 years old, it might be time for a replacement.


5. Sewer Line Problems

Tree roots love the clay-rich soil in East Tennessee — and they’ll sneak into your sewer line if given the chance.

Fix it: Watch for slow drains or foul smells. Regular inspections and trenchless repairs can save you thousands.
