A slow-draining sink is usually an early warning sign of a blockage forming in your pipes. Catching it early can prevent more serious problems later.
Common causes
Hair and soap scum are the main culprits in bathroom sinks, while grease and food debris commonly block kitchen sinks. Limescale build-up in older pipes can also restrict flow.
DIY fixes
Boiling water can help loosen grease. Baking soda and vinegar can clear mild build-ups. Cleaning the plughole and P-trap often restores normal drainage. A simple drain snake can remove trapped hair.
Avoid chemical drain cleaners where possible, as they can damage pipes.
When to call a plumber
If multiple sinks are slow, foul smells persist, or DIY methods don’t work, the issue may be deeper in the system.
