How to Fix a Slow Drain (And When to Call a Plumber)

A slow drain doesn’t always mean a major plumbing issue — but ignoring it can turn a small clog into a backed-up sink or overflowing tub.

Here’s how to troubleshoot it and when to call a pro.

Common Causes of Slow Drains

• Hair buildup

• Soap scum

• Grease or food waste

• Mineral buildup

• Partial blockages deeper in the pipes

DIY Fix #1: Hot Water Rinse

Pour hot water in stages to dissolve grease and soap scum.
Avoid for PVC pipes.

DIY Fix #2: Baking Soda + Vinegar

A safe, natural solution.

1. Pour ½ cup baking soda

2. Add 1 cup vinegar

3. Let sit 15 minutes

4. Rinse with hot water

DIY Fix #3: Remove and Clean the Stopper

Bathroom sinks clog easily because of hair.
Pull out the stopper, clean debris, and reinstall.

DIY Fix #4: Use a Drain Snake

Most hardware stores carry inexpensive drain snakes that remove hair clogs easily.
