Common causes

Hair and soap scum

The most common cause in tubs and showers.

Clogged stopper or pop-up

Debris wraps around the stopper mechanism.

Grease in kitchen lines

Builds up gradually.

Blocked vent

Air cannot enter, so water drains slowly and may gurgle.

What you can check yourself

  • Pull and clean the stopper.
  • Use a plunger with a little water in the basin.
  • Try a plastic drain-cleaning strip for hair.
  • Check whether nearby fixtures are also slow.

When to call a plumber

If cleaning the stopper does not help, or several fixtures are slow, schedule drain cleaning.

How a plumber diagnoses it

A plumber snakes the branch line and checks the vent if gurgling is present.

What it may cost

See the drain cleaning cost guide for published price ranges and cost factors.
