What to do when a sink drains slowly
Hair, soap and food residue can gradually restrict a drain. Start with the simplest accessible areas and avoid forcing anything.
What you can check
- 01
Remove visible debris from the drain opening while wearing gloves. Lift out a removable stopper if it comes away easily, then clean and replace it.
- 02
Run warm water and see whether the flow improves. A small sink plunger may help; use it gently with enough water to cover its rim.
- 03
If the drain still backs up, note whether other fixtures are affected and ask for help.
Safety first
Do not mix drain chemicals or plunge after using them: splashes can cause serious burns. Stop if wastewater backs up into other fixtures.
When to ask for help
Get professional help for repeated clogs, sewage, leaks under the sink or a blockage that does not clear.
