The CSB INTERNATIONAL PRODUCTS CSB3814D-16CP is a double flanged tailpiece designed for drain line connections in residential and light commercial plumbing applications. Constructed from 20-gauge material, this tailpiece measures 1.5 inches in diameter and 16 inches in length, providing a reliable transition between a sink drain basket or strainer and the trap assembly below. The double flange design adds structural reinforcement at the connection points, reducing the risk of leaks under typical drain line stress. Licensed plumbers and experienced plumbing contractors install this component as part of standard sink rough-in and replacement work.
This tailpiece is suited for use in kitchen and bathroom sink drain assemblies where a 1.5-inch drain line is required. It is commonly installed during new construction, remodel projects, and drain repair work. The 16-inch length accommodates standard cabinet depths and allows for correct trap alignment without the need for additional extensions in most residential configurations.
Designed as an OEM-style replacement or new-installation tailpiece for standard 1.5-inch residential and light commercial sink drain assemblies.
Installation is performed by a licensed plumber or qualified plumbing professional. Shut off water supply and clear standing water from the drain system before beginning work. Ensure proper alignment with the trap arm to avoid stress on fittings. Follow local plumbing code requirements, including those referenced in the IPC, for drain assembly clearances and connection methods.
