Description
The T&S Brass B-3970-01-XS Waste Drain Valve provides an integrated safety and space-saving solution for professional sculleries. This unit features a 3-1/2″ sink opening, an integrated Overflow Assembly to prevent overfill, and a Short Lever Handle designed for installations with restricted clearance. Constructed from heavy-duty cast bronze and stainless steel, it directs excess water safely into the waste line while offering remote drainage control without the interference of a full-sized lever. Includes 1-1/2″ NPT adapter.
Maintenance Tip: The combined overflow and short handle configuration is the premier choice for compact high-safety kitchen basins. During installation, ensure the overflow tubing has a consistent downward pitch to prevent stagnant water. The short lever provides a high mechanical advantage while clearing obstacles. Polished stainless steel finish on the strainer is exceptionally resistant to grease and chemical splashes. Always flush building lines through the body.
