why is my drain trap leaking water

Plumbing

The answer to 'why is my drain trap leaking water' is that a leaky drain trap is a common plumbing issue, often caused by a worn-out or improperly installed trap. The drain trap is the U-shaped pipe under your sink that holds a small amount of water to prevent sewer gases from entering your home.

Common causes of a leaky drain trap include cracks in the trap, loose connections, or a trap that wasn't properly sealed during installation. This can lead to water dripping out and causing damage to the cabinet or floor underneath. Symptoms of a leaky trap include water pooling around the base of the sink, a musty odor, or visible water dripping.

Step-by-Step Guide

  1. 1

    Inspect the drain trap

    Start by examining the drain trap for any cracks, loose connections, or signs of wear. Tighten any fittings that seem loose.

    Replace the drain trap gasket

    If the trap appears intact but is still leaking, try replacing the rubber gasket that seals the trap to the sink drain.

    Replace the entire drain trap

    If the trap is cracked or the leak persists, you'll need to replace the entire U-shaped trap assembly.
