Built for heavy-use wash stations, this modular waste drain valve combines durable construction with service-friendly design to keep kitchen drains operating reliably under high throughput. Its pull-handle actuation provides intuitive, positive control for fast drain clearing, and the 3-1/2" sink opening fits standard commercial sinks to simplify installation and replacement.
LongDescription#@#NA#@@#Cleaning Instructions#@#Unplug the sink fixture if possible and remove the waste drain valve. Wipe the modular waste drain valve (T&S Brass B-3990) with a mild detergent and warm water, scrubbing the pull handle and 3-1/2" opening with a soft brush to remove grease and debris. Rinse thoroughly and dry all surfaces to prevent corrosion. Inspect the 2" NPT female x 1-1/2" NPT male adapter threads for wear and replace if damaged. Reinstall tightly and test for leaks before returning to service.#@@#Additional Info#@#T&S Brass B-3990 Modular Waste Drain Valve has a pull handle for 3-1/2" sink openings, includes a 2" NPT female to 1-1/2" NPT male adapter, and features durable brass construction for easy installation in commercial kitchens.#@@#General Info#@#Description #@#
Built for heavy-use wash stations, this modular waste drain valve combines durable construction with service-friendly design to keep kitchen drains operating reliably under high throughput. Its pull-handle actuation provides intuitive, positive control for fast drain clearing, and the 3-1/2" sink opening fits standard commercial sinks to simplify installation and replacement.
#@@# Pull Handle Operation#@#
The pull-handle mechanism gives operators direct mechanical control for immediate valve actuation, reducing response time during sink use. Two to three motions clear drain passages without complex tooling, lowering training time for staff.
#@@# Standard Sink Fit#@#
Designed for a 3-1/2" sink opening, the valve mates with common commercial sink cutouts to streamline retrofits and spare-part stocking. This compatibility reduces downtime by eliminating the need for custom modifications.
#@@# Threaded Adapter Connection#@#
The unit includes a 2" NPT female to 1-1/2" NPT male adapter, enabling secure connections to existing drain piping and standard plumbing fittings. Field technicians can complete installations using common thread sizes and standard sealing practices.
#@@# Modular Serviceability#@#
Engineered as a modular assembly, the valve allows individual components to be serviced or replaced without removing adjacent fixtures. Maintenance crews can perform targeted repairs faster, extending overall system uptime.
#@@# Commercial-Grade Materials#@#
Manufactured by an established plumbing supplier, the drain valve uses materials suited for repeated daily use in foodservice environments. The robust build withstands frequent handling and the mechanical stresses of busy sinks.
#@@# Compact Footprint#@#
With a focused profile for under-sink placement, the valve occupies minimal space while delivering full drain functionality. Layout planners can integrate the unit into crowded cabinets or service consoles without significant reconfiguration.
