The T&S B-3952 twist waste valve is essential for a sink that you need to fill with water. The valve allows the operator to stop water from draining without putting their entire arm into the sink to plug the drain. Featuring a twist handle with a heat-resistant plastic grip, this valve makes opening and closing the drain as easy as turning the handle! It includes a 3 1/2" snap-in removable strainer and overflow outlet with a cap and sealing washer, allowing you to easily adjust the valve to fit the needs of your establishment. The rough chrome-plated brass body ensures longevity of this product. This valve is designed for 3 1/2" sink openings and has a 2" NPT / 1 1/2" FPT drain outlet.
