The BSC PREFERRED LK500 is a 1-1/2 inch P-trap with a cleanout plug designed for residential drain waste systems in kitchens, bars, and laundry areas. It includes a 1-1/2 inch O.D. tubing waste arm and a wall flange for a secure connection to standard drain rough-ins. The center of the drain inlet measures 12 inches from the wall, fitting typical cabinet and countertop setups. The cleanout plug provides direct access to the trap interior for clearing blockages without disassembling the drain stack. Licensed plumbers and experienced trade installers use this fitting as a primary P-trap solution where serviceability is a priority.
This P-trap is suited for residential and light commercial applications including kitchen sinks, bar sinks, and laundry tubs. The 12-inch inlet-to-wall centerline dimension is compatible with standard North American plumbing rough-in configurations. The included wall flange and tubing waste arm reduce the need for additional transition fittings at the wall connection. The cleanout plug is particularly useful in high-use kitchen and bar installations where grease-related blockages are more frequent and require periodic trap servicing.
Designed as an OEM-style replacement or new-installation P-trap for 1-1/2 inch drain waste systems in residential kitchens, bar sinks, and laundry areas using standard North American drain rough-in configurations.
Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and the International Plumbing Code (IPC). Shut off the water supply and clear standing water from the drain before beginning work. Hand-tighten slip-joint nuts to avoid cracking fittings, and verify the trap seal is maintained at the correct water level after installation. Confirm all connections are leak-free under running water before returning the fixture to service.
