Description
The T&S Brass B-3952 Twist Waste Valve is a heavy-duty industrial workhorse designed for professional commercial basins. Featuring a 3-1/2″ sink opening and a high-flow 2″ NPT male outlet, it provides the rapid drainage required for massive commercial sinks. The twist-action remote control allows operators to drain the basin without reaching into hot or contaminated water, promoting superior workplace safety and hygiene. Constructed from durable cast bronze and stainless steel, it is built for extreme longevity in demanding foodservice environments.
Technician’s Note: The B-3952 is the foundational standard for professional drainage. During installation, ensure the mounting flange is tightened hand-tight plus a quarter turn to prevent basin leaks. The 2″ NPT outlet also features 1-1/2″ female internal threads for maximum plumbing flexibility. Regularly inspect the internal plunger seat for food particles that can prevent a watertight seal. Polished stainless steel strainer provides a professional appearance.
