The SLOAN 3308859 is a 3/4 inch stop kit designed for use with concealed flush valve installations. This assembly includes the wheel handle and stop mechanism that controls water supply to a concealed-body flush valve, allowing service technicians to shut off flow to the valve without interrupting the main water supply. It is a direct service and maintenance component used by licensed plumbers and commercial plumbing contractors in restroom fixture work. The kit weighs 0.172 pounds, making it a compact, lightweight assembly suited for tight wall-cavity access.
This stop kit is typically installed in commercial and institutional restroom applications where concealed flush valves are mounted within wall assemblies or recessed carrier systems. It is used in new construction and retrofit work where the existing stop requires replacement due to wear, damage, or valve servicing needs. Plumbing contractors working on commercial water closet and urinal flush valve systems will encounter this component in standard rough-in configurations.
Designed as an OEM-style replacement stop kit for SLOAN concealed flush valve systems requiring a 3/4 inch wheel handle stop assembly.
Installation should be performed by a licensed plumber in accordance with local plumbing codes and the IPC. Shut off the water supply upstream of the flush valve before beginning any stop kit replacement. Use appropriate basin wrenches or valve tools rated for the connection size when removing and seating the stop assembly. Do not overtighten packing nuts or compression fittings, as concealed valve bodies may not allow easy access for rework.
