The DIY Drain Clearing Guide

Before you call a plumber ($$), try these proven methods to clear common drain clogs yourself. Most clogs can be cleared in 15-30 minutes with tools you already have.

Method 1: The Boiling Water Treatment

Best for: Minor clogs from soap buildup

What you need: Just a kettle of boiling water

Steps: 1. Boil a full kettle of water 2. Pour it slowly down the drain in 2-3 stages 3. Wait a few seconds between pours 4. Repeat if needed

Why it works: Hot water melts soap scum and grease that cause minor blockages.

⚠️ Warning: Don't use boiling water on PVC pipes or if you have standing water (it could splash back).

Method 2: Baking Soda + Vinegar

Best for: Moderate clogs and odor removal

What you need:

• 1/2 cup baking soda
• 1/2 cup white vinegar
• Boiling water

Steps: 1. Remove any visible debris from drain 2. Pour baking soda down the drain 3. Follow with vinegar 4. Cover drain and wait 15-30 minutes 5. Flush with boiling water

Why it works: The chemical reaction creates fizzing action that breaks up gunk. Plus, it deodorizes!

Method 3: The Plunger Method

Best for: Stubborn clogs that resist other methods

What you need:

• Cup plunger (not a flange plunger—that's for toilets)
• Petroleum jelly (optional)

Steps: 1. Remove drain stopper if present 2. Fill sink with 2-3 inches of water 3. Apply petroleum jelly to plunger rim for better seal 4. Place plunger over drain, ensuring full seal 5. Plunge vigorously 15-20 times 6. Pull plunger away quickly 7. Repeat as needed

Pro tip: Block the overflow hole with a wet rag for better suction.

Method 4: The Drain Snake

Best for: Deep clogs beyond the P-trap

What you need:

• Drain snake (also called a drum auger)
• Bucket
• Gloves

Steps: 1. Insert snake into drain 2. Turn handle clockwise while pushing forward 3. When you feel resistance, you've found the clog 4. Rotate and push to break it up 5. Pull snake out slowly 6. Run hot water to flush debris

• Multiple drains are clogged (sewer line issue)
