Keeney 400WK White Plastic P-trap 1-1/2 Inch

Product Description

The KEENEY 400WK is a white plastic P-trap designed for 1-1/2 inch tubular drain applications under sinks and lavatories. The trap holds a water seal that blocks sewer gases from entering the occupied space while allowing wastewater to flow freely. The kit ships with all necessary nuts and washers for a secure, leak-resistant connection, plus a wall flange that covers the drain pipe opening at the wall for a clean finished appearance. A licensed plumber or experienced tradesperson can install this fitting in standard residential or light commercial drain configurations.

This P-trap is suited for kitchen sinks, bathroom lavatories, and utility sinks where a 1-1/2 inch tubular drain connection is required. It is a common replacement in older drain assemblies where plastic components have cracked, yellowed, or failed at the slip-joint connections. The included hardware eliminates the need to source separate slip-joint nuts or washers, making it a straightforward service or retrofit part.

Installation Notes

Installation is typically performed by a licensed plumber or qualified tradesperson in accordance with the applicable IPC or local plumbing code. Shut off the water supply and clear standing water from the drain before removing the existing trap. Hand-tighten slip-joint nuts first, then snug with channel-lock pliers — do not over-torque plastic fittings. Verify the water seal is fully charged by running water through the drain and inspect all joints for leaks before closing out the service call.
