The T&S Brass B-3940-01-BSP Waste Drain Valve is an elite safety component for international professional sinks requiring BSP threaded connections. This unit features a 3" sink opening and an integrated Overflow Assembly to protect facilities from basin overfill. It includes a BSP adapter for compatibility with global plumbing manifolds. Constructed from heavy-duty cast bronze and stainless steel, it provides a hygienic, remote-controlled drainage solution that is built for extreme longevity in high-volume research and foodservice facilities.
Technician’s Note: Overflow assemblies are critical for preventing accidental floods in busy sculleries. The "BSP" designation indicates compatibility with international plumbing standards—verify your building manifold before installation. During setup, ensure the overflow tubing has a consistent downward slope to prevents stagnant water. Polished stainless steel strainer finish is highly resistant to aggressive cleaning agents.
