Arrived on site to diagnose a leaking drain under the sink. Found a failed P-trap assembly with worn slip joint washers and improperly aligned PVC causing slow drainage and active leaks. Removed the damaged P-trap and existing PVC piping. Installed a new P-trap assembly and replaced affected PVC drain sections, ensuring proper slope, tight connections, and code-compliant alignment. Tested the system thoroughly after installation—no leaks present and drainage flowing properly. Customer was informed of the repair, shown the completed work, and advised on proper drain use to prevent future issues.
