Why Is Your Sink Draining Slowly?

A slow-draining sink usually means a blockage forming in the pipes.
 
The most common causes include:
  • Hair buildup
  • Soap scum
  • Food scraps (kitchen sinks)
  • Grease or oils
DIY Fix: Step-by-Step Guide
 
1. Use Boiling Water
 
Pour boiling water down the drain to melt soap scum or oils blocking the pipe.
 
2. Try a Baking Soda + Vinegar Flush
  • Pour ½ cup of baking soda
  • Add 1 cup of vinegar
  • Let it fizz for 10–15 minutes
  • Rinse with hot water
3. Clean the P-Trap
 
If the blockage persists:
  • Place a bucket underneath
  • Unscrew the trap
  • Remove debris
  • Reinstall and test
4. When to Call a Plumber
 
If multiple drains are slow, the issue may be deeper in your drainage system. Professional equipment may be required.
