To clean a P-trap (the U-shaped pipe under a sink), follow these steps:
- Prepare the workspace by placing a bucket or bowl underneath the P-trap to catch water and debris. Keep a towel handy.
- Loosen the slip nuts on either side of the P-trap by hand or with pliers/wrench and carefully remove the P-trap.
- Empty the water and debris into the bucket. Take the P-trap to a different sink or outside and wash it out with water.
- Use vinegar and a brush or a flexible wire brush to scrub the inside and remove built-up grime, hair, and grease.
- Check for any obstruction or debris in the pipes connected to the P-trap.
- Reattach the P-trap by tightening the slip nuts securely but not overtightened.
- Run water to test for leaks and tighten the nuts a bit more if needed.
Cleaning the P-trap regularly prevents slow drainage and unpleasant odors by removing accumulated debris inside it. This is a simple DIY plumbing maintenance task that improves sink performance and protects against sewer gases entering the home.
