Intro: A slow‑draining sink is usually caused by a blockage close to the top of the pipe.
1. Clean the plug
Hair and soap scum build up quickly.
2. Use boiling water
Helps break down grease.
3. Use a plunger
Creates pressure to clear blockages.
4. Check the U‑bend
Unscrew it and remove debris.
5. When to call a plumber
If the blockage is deeper.
Summary: Most slow drains are caused by hair, soap, or grease build‑up.
