How to Unclog a Drain: 5 Methods That Actually Work
A clogged drain is one of the most common household problems. Before calling a plumber ($150–$300), try these proven DIY methods first.
Method 1: Boiling Water (Free — Try First)
Boil a full kettle and slowly pour it down the drain in 2–3 stages, letting it work for a few seconds between pours. Works best on grease and soap scum clogs. Do NOT use on PVC pipes — use hot tap water instead.
Method 2: Baking Soda + Vinegar
- Pour 1/2 cup of baking soda down the drain
- Follow with 1/2 cup white vinegar
- Cover the drain and wait 15–30 minutes
- Flush with hot water
The fizzing reaction helps break down organic matter. Effective for mild clogs.
Method 3: Plunger
Use a cup plunger for sinks and a flange plunger for toilets. Create a tight seal and use quick, firm plunges — about 15–20 strokes. Remove and check for drainage. Repeat 2–3 times.
Method 4: Drain Snake (Auger)
Feed a hand drain snake (available for $20–$30 at hardware stores) into the drain until you hit resistance. Rotate to break through or hook the clog, then pull out the debris. This works for deeper clogs that plungers can\’t reach.
Method 5: Remove and Clean the P-Trap
Place a bucket under the curved pipe beneath your sink. Unscrew the P-trap by hand (or with pliers). Remove any blockage, clean the trap, and reinstall. This is the most effective fix for persistent sink clogs.
What NOT to Use
- Chemical drain cleaners (like Drano) — can damage pipes over time and are harmful to the environment
- Wire coat hangers — can scratch and damage pipe interiors
