T&S Brass supplies a modular waste drain valve engineered for commercial sinks with a 3-1/2" opening, delivering reliable drainage control for high-use kitchen environments. Designed for compatibility with standard plumbing, this unit accepts a 2" NPT male inlet and provides a 1-1/2" female outlet, facilitating integration with common drain configurations and minimizing retrofit complexity.
LongDescription#@#NA#@@#Cleaning Instructions#@#Unplug the sink drain area and remove any debris. Disassemble the T&S Brass B-3992 Modular Waste Drain Valve by unscrewing the flange and lifting the 3-1/2" strainer assembly, then detach the 2" NPT male / 1-1/2" female outlet connections if needed. Soak metal parts in warm water with mild detergent, scrub with a soft brush to remove grease and scale, and rinse thoroughly. Inspect seals and replace worn gaskets. Reassemble tightly, test for leaks, and run water to confirm proper drainage.#@@#Additional Info#@#The T&S Brass B-3992 waste drain valve fits a 3-1/2" sink opening, has a 2" NPT male inlet, 1-1/2" female outlet, weighs 8.75 lbs, and is designed for easy installation and maintenance in commercial kitchens.#@@#General Info#@#Description #@#
T&S Brass supplies a modular waste drain valve engineered for commercial sinks with a 3-1/2" opening, delivering reliable drainage control for high-use kitchen environments. Designed for compatibility with standard plumbing, this unit accepts a 2" NPT male inlet and provides a 1-1/2" female outlet, facilitating integration with common drain configurations and minimizing retrofit complexity.
#@@# Compact Sink Interface#@#
The valve fits a 3-1/2" sink opening, ensuring a precise seal and consistent operation in busy foodservice settings. Installers benefit from predictable dimensions that reduce installation time and the need for custom adaptations.
#@@# Standard Outlet Configuration#@#
Equipped with a 1-1/2" female outlet, the assembly connects directly to common trap and waste lines used in commercial kitchens. Technicians avoid auxiliary couplings when piping to existing drainage systems, preserving flow efficiency.
#@@# NPT Male Inlet#@#
The unit uses a 2" NPT male inlet to mate with threaded drain fittings, offering a secure mechanical connection under frequent use. Maintenance teams can rely on the threaded interface for straightforward removal and replacement during service intervals.
#@@# Modular Construction#@#
Manufactured as a modular valve, the design simplifies part-level servicing and component swaps without removing the entire assembly. Facilities reduce downtime and service labor by exchanging modules instead of complete valves.
#@@# Commercial Duty Design#@#
Built for restaurant and institutional environments, the valve withstands repetitive cycling and continuous operation common in foodservice applications. Operators gain consistent performance that supports peak service periods.
#@@# Installation Efficiency#@#
The valve’s dimensional and connection standards streamline retrofit and new-install projects in kitchens, bars, hospitals, and schools. Plumbers complete installations faster, lowering labor hours and keeping service lines operational.
