Slow or clogged drains can range from a simple fixture blockage to a larger drainage concern. Start with the lowest-risk steps and stop before a DIY effort becomes a damaged fixture, a chemical hazard, or a recurring problem that needs diagnosis.
Start with the right plunger
A cup plunger is generally used for sinks and tubs, while a flange plunger is designed for toilets. Create a good seal and use firm, controlled strokes. If the clog clears and does not return, no further action may be needed.
Use drain tools carefully
A hand-crank snake can help with some hair clogs and minor fixture blockages. Do not force a cable if it will not advance easily or if resistance is severe. Stop if you are unfamiliar with the fixture or the tool, and avoid turning a simple clog into pipe or fixture damage.
Avoid chemical-cleaner hazards
Do not mix chemical drain cleaners or add another product to a drain that already contains one. Follow product-label instructions and tell a plumber if a chemical has been used. Chemical products can create hazards and may complicate professional work.
When professional help makes sense
- Multiple fixtures are slow or clogged at the same time.
- The clog returns after clearing attempts.
- You hear gurgling from other fixtures.
- Wastewater backs up into a tub, shower, or sink.
- A basic plunger or safe, careful cleaning does not resolve the issue.
