Installing the Bathroom Sink Drain P-Trap

Begin by shutting off the water supply under the sink and draining any residual water. Disconnect the old trap by removing its nuts using an adjustable wrench. Clean the drain pipe and insert the new p trap, aligning its slip threads with the pipe. Secure it with the provided nuts, tightening securely but avoiding over-tightening to prevent cracking. Connect the drain tailpiece to the pipe below and attach the overflow tube if included. Ensure all connections are watertight using plumber’s tape. Finally, restore water flow and check for leaks by running water and inspecting around the trap connections.
