T&S Brass B-3970 Commercial Lever Waste Valve with 3.5-Inch Sink Opening

Improve the efficiency of your commercial sink stations with the T&S Brass B-3970 lever waste valve. This heavy-duty drain component is specifically designed to handle the rigorous daily demands of busy commercial kitchens and dishrooms. Featuring a standard 3-1/2 inch sink opening, this valve provides a reliable solution for fast and effective water drainage.

A removable snap-in strainer helps capture food debris before it enters the plumbing system, while the provided waste drain overflow cap with a sealing washer ensures secure operation.
