The BSC PREFERRED DIB100CP is a 1-1/4 inch seamless brass P-trap finished in 22-gauge chrome plating. P-traps create the water seal that blocks sewer gases from entering occupied spaces through the drain line. This unit ships with flange nuts and washers, so all connection hardware is included at installation. The seamless construction eliminates a common leak point found in welded or joined trap bodies. At 0.6 pounds, the trap is lightweight enough for easy single-hand positioning during fitting. It is a standard drain fitting installed by licensed plumbers and experienced pipefitters in both new construction and retrofit drain applications.
This P-trap is suited for residential and light commercial drain applications where a 1-1/4 inch trap arm connection is specified, such as bathroom lavatories and small utility sinks. The chrome-plated finish is appropriate for exposed under-sink installations where appearance matters. Because hardware is included, no separate procurement of nuts and washers is required to complete a standard connection.
Designed as an OEM-style replacement or new-installation P-trap for residential and light commercial 1-1/4 inch drain assemblies, including bathroom lavatories and utility sinks.
Installation is performed by licensed plumbers in accordance with the applicable International Plumbing Code (IPC) or local equivalent. Shut off the water supply and clear the trap of standing water before removing any existing trap. Hand-tighten flange nuts first to seat washers evenly, then snug with slip-joint pliers — avoid over-tightening, which can crack the nut or distort the washer. After installation, run water and inspect all connections for leaks before returning the drain to service.
