How to unclog a drain

Most drain clogs can be cleared using a plunger, drain snake, or baking soda and vinegar mixture to break up hair, soap, and debris blocking the pipe.

  1. Start with the plunger method. Remove the drain cover or stopper if possible. Fill the sink or tub with enough water to cover the plunger cup. Place the plunger over the drain opening and pump vigorously 15-20 times. Pull the plunger away quickly to create suction that can dislodge the clog. Repeat this process 2-3 times, then run hot water to see if the drain flows freely.
  2. Try the baking soda and vinegar treatment. Pour one cup of baking soda directly down the drain, followed by one cup of white vinegar. The mixture will foam and bubble. Cover the drain with a wet cloth or stopper to contain the reaction. Wait 30 minutes, then flush with very hot water. This method dissolves soap buildup and breaks down organic matter like hair.
  3. Use a drain snake for stubborn clogs. Insert the drain snake (also called a drain auger) into the drain opening. Turn the handle clockwise while pushing the snake deeper into the pipe. When you feel resistance, you've likely reached the clog. Continue turning and pushing to break through or hook the obstruction. Pull the snake out slowly, bringing the clog material with it. Run hot water to clear any remaining debris.
  4. Remove and clean the P-trap if needed. For sink drains that remain clogged, place a bucket under the P-trap (the curved pipe under the sink). Unscrew the slip nuts on both ends of the P-trap using channel-lock pliers. Remove the trap and empty any water and debris into the bucket. Clean the trap thoroughly with hot water and a bottle brush, then reinstall by hand-tightening the slip nuts. Run water to check for leaks and proper drainage.
  5. Prevent future clogs. Install drain screens to catch hair and debris before they enter the pipes. Run hot water after each use to help dissolve soap and oil buildup. Once a month, pour hot water down drains followed by a small amount of dish soap to maintain clear flow. Avoid putting grease, coffee grounds, or large food particles down kitchen drains.
