Clear a slow kitchen sink

Try gentle surface-level steps when a kitchen sink drains slowly but is not overflowing.

About 10 minutesNo special tools

Safety first

Do not use caustic drain cleaner or disassemble the trap or other plumbing.

Written steps

  1. Remove visible food or debris from the strainer using a paper towel or disposable glove.
  2. Run warm, not boiling, water for 30 seconds.
  3. If the basin still drains slowly, use a small sink plunger with enough water to cover its rim.
  4. Stop and request maintenance if the drain remains blocked or water backs up elsewhere.

Stop and request maintenance if

  • Water is overflowing or backing up into another fixture.
  • You already used chemical drain cleaner.
  • There is a leak below the sink.
