Sink Drains Slowly? Why It Happens and the Right Way to Clear It

By Done Wright Plumbing · Updated 2026-11-05

A sink that drains slowly is an early warning. Ignore it and you get a full clog, often on a weekend.

Kitchen sinks: grease and food

Grease cools and hardens on pipe walls, then catches food particles. Hot water and soap only move it further down the line.

Bathroom sinks: hair and soap scum

Hair wraps around the pop-up stopper and soap binds it into a mat.

Scale in older pipes

Hard California water deposits scale inside cast iron and galvanized drains, narrowing the pipe. Hydro jetting scours it away.

Vent problems

If the sink gurgles, a blocked vent stack may be the cause rather than the drain itself.

Why skip chemical drain cleaners

They corrode pipes, rarely clear the full clog and make a plumber's job hazardous. Professional drain cleaning uses a cable or jetter that removes the blockage completely, and a camera inspection confirms the pipe is clear.
