The BSC PREFERRED DIB812-1 is a flexible sink drain tailpiece designed for standard residential and light commercial sink drain applications. The fix-and-flex design allows for minor alignment adjustments during installation, reducing the need to cut or refit rigid drain pipe. At 1-1/2 inches in diameter and 12 inches in length, this tailpiece connects the sink basket strainer to the P-trap below. It is installed by licensed plumbers and experienced service technicians working on kitchen or bathroom sink drain assemblies.
This tailpiece is suited for residential kitchens, bathrooms, and utility sinks where the drain outlet and trap inlet are not perfectly aligned. The flexible body accommodates minor offset conditions without requiring additional fittings. Its 1-1/2 inch diameter is the standard size for most household sink drain configurations in North America.
Designed as an OEM-style replacement tailpiece for standard 1-1/2 inch residential and light commercial sink drain assemblies.
This tailpiece is installed by licensed plumbers or qualified drain technicians. Shut off the water supply and clear standing water from the drain before beginning disassembly of the existing trap and tailpiece. Hand-tighten slip-joint nuts first, then snug with slip-joint pliers - avoid overtightening, which can crack slip-joint fittings. Verify all connections are leak-free before returning the fixture to service.
