Our ​​twist waste valves​​ are ideal for high-traffic commercial kitchens due to their durable brass and stainless steel construction and smooth twisting mechanism that resists clogging. Unlike lever-operated valves, our ​​twist waste drain valves​​ feature an ergonomic hand grip for quick operation while maintaining a watertight seal. Standard ​​commercial sink waste drain valves​​ are either 3-1/2” sink opening in diameter—choose based on your sink’s drainage capacity.
