Clogged Drain

When one fixture backing up starts pulling water into another one, the blockage has moved past the trap into shared pipe and it needs opening before a toilet finds the floor.

When this becomes an emergency

What a pro does

The first question on a clogged drain call is how many fixtures are involved, because one slow sink and a whole slow house are different jobs. A single trap gets cleared mechanically at the fixture. When several drains on the same side of the house are sluggish, the plumber moves to the branch line or the main and works from a cleanout instead. Older Knoxville housing complicates this. Homes in Island Home Park and Park City frequently still run cast iron below the floor, and decades of scale build a rough interior surface that catches grease and hair in a way smooth plastic never does, so the same drain clogs again on a schedule. A camera goes down the line when the pattern repeats, since that separates a soft blockage from a belly in the pipe or a root that's found a joint. Clearing gets matched to the cause. A cable cuts through a soft mass, while heavier scale and grease usually call for water jetting to actually take the walls back down to pipe.

Frequently asked questions

Usually because the blockage was cut through rather than cleaned out, or because the pipe itself is rough inside. Cast iron that's been in the ground since the 1940s holds onto grease at every scale ridge, so the line refills from the same spots each time.
They tend to make the visit harder. What doesn't clear sits in the trap as caustic standing water, and repeated use is unkind to older cast iron and to the rubber in fixture connections.
That the blockage sits downstream of both of them, in pipe they share. That's a branch or main line problem rather than a trap, and it's the point where waiting usually costs more than calling.
Not inside, but they're a common cause just outside it. Mature silver maples and sweetgums along older East Tennessee streets send roots straight to the moisture at a joint in the lateral, and the intrusion shows up indoors as drains that all slow at once.
