How to Clean a PVC P-Trap

Introduction

If your sink is slow to drain or is not draining, the cause may be a clog in the P-trap. Use this guide to disassemble and clear any clogged hair and soap scum from the P-Trap.

The P-Trap is P shaped piping that directly follows the drain stopper and is usually located in the cabinets below a sink. The P-Trap is mainly intended to hold water in the bend with the intent of blocking foul smelling air from deeper within the plumbing of a house from coming out through the sink. It also serves the secondary purpose of catching small items dropped into the sink and allowing them to be retrieved.

Before beginning, ensure water to the sink being worked on is shut off and that your workspace is prepped for any potential spills.
