Fixing a leaky kitchen sink trap without calling a plumber
In short: A leaky, glued-together sink trap can be a frustrating household nuisance. This guide from This Old House demonstrates how to properly remove and replace a faulty PVC assembly using standard tools.
Plumbing expert Richard Trethewey explains the process of replacing a kitchen-sink trap, specifically focusing on units that are glued together. The project requires specific tools like a reciprocating saw to remove the old trap and a drill with a special PVC cutterhead to open the existing drainpipe.
The process involves preparing a workspace with a foil pan to catch water and using paper towels to identify exactly where leaks occur. Once the old trap is removed, a new assembly is built using 1 1/2-inch-diameter PVC pipes and fittings, which are then secured using PVC primer and cement.
