Common Causes of Kitchen Sink Clogs

Kitchen sinks clog more than any other drain in the house, mostly from a predictable set of culprits that build up gradually over time.

Grease and Oil

Even small amounts poured down the drain regularly coat the inside of the pipe and harden, narrowing the passage until other debris catches and blocks it entirely.

Food Particles Past the Disposal

A disposal grinds food but doesn't eliminate it; fibrous or starchy scraps can still accumulate in the drain line just past the trap.

Soap and Detergent Residue

Dish soap residue combines with grease and food particles to form the stubborn buildup that eventually needs professional cleaning to fully clear.
