Bsc Preferred DIB20940 Plastic P-trap 1-1/2 Inch White

Product Description

The BSC PREFERRED DIB20940 is a 1-1/2 inch white polypropylene P-trap designed for drain line applications in residential kitchens and bathrooms. The trap creates a water seal that blocks sewer gases from entering the living space while allowing wastewater to pass freely. It includes an integrated 1-1/2 inch by 1-1/4 inch reducer washer for compatibility with 1-1/4 inch pipe connections, along with all required nuts and washers for a complete assembly. All connections are hand-tightenable, eliminating the need for tools during installation. Plumbers and qualified plumbing contractors are the typical installers for this type of drain fitting.

The DIB20940 P-trap is suited for residential sink drain installations including kitchen sinks and bathroom lavatories. The white polypropylene finish blends with standard white fixture finishes. The included reducer washer expands the range of installations by allowing connection to both 1-1/2 inch and 1-1/4 inch drain tailpieces without sourcing a separate adapter. All necessary hardware ships with the fitting, making it a ready-to-install replacement or new-construction drain component.

Installation Notes

Installation is typically performed by a licensed plumber or qualified plumbing contractor in accordance with local plumbing codes and the International Plumbing Code (IPC). Shut off the water supply and clear standing water from the drain line before beginning work. Hand-tighten all slip-joint connections and check for leaks after restoring flow — do not overtighten polypropylene fittings, as excess force can crack the material. Verify local code acceptance of plastic P-trap fittings for the intended application before installation.
