Step-by-Step Instructions

1

Remove visible debris

5 minutes

Remove the drain cover or stopper. Use a flashlight to look for visible clogs (hair, soap buildup). Remove what you can reach by hand or with needle-nose pliers.

Pro Tip

Bathroom drains are usually clogged with hair. A bent wire hanger can help pull out hair clogs.

2

Try the plunger

5-10 minutes

Add enough water to cover the plunger cup. Create a seal over the drain and plunge vigorously 15-20 times. Check if water drains. Repeat if needed.

Pro Tip

For sinks with overflow holes, cover the overflow with wet cloth to maintain suction.

3

Try baking soda and vinegar (optional)

15-30 minutes

Pour 1/2 cup baking soda down the drain, followed by 1/2 cup white vinegar. Cover and wait 15-30 minutes. Flush with hot water.

Pro Tip

This works best for minor clogs and maintenance, not severe blockages.

4

Use a drain snake

10-20 minutes

Insert the snake into the drain and push while rotating the handle clockwise. When you feel resistance, you've hit the clog. Continue rotating to break up or hook the clog. Pull out slowly, bringing debris with it.

Pro Tip

Clean off the snake as you pull it out. You may need to repeat several times.

Flush and test

5 minutes

Run hot water for several minutes to flush the drain. Check that water drains quickly without backing up.

Common Mistakes to Avoid

  • Using chemical drain cleaners that can damage pipes
  • Not creating a good seal with the plunger
  • Pushing the clog deeper instead of pulling it out
  • Giving up too soon with the snake

Safety Warnings

  • Wear rubber gloves when handling drain debris
  • Never use a plunger after using chemical drain cleaner (can splash chemicals)

When to Call a Professional

If multiple drains are slow (main line issue), if you hear gurgling from other drains, or if repeated snaking doesn't help. Also call a pro if you have old pipes that might be damaged.
