FlowRite WP-SL06D Water Closet Flushometer Drop In Kit

FlowRite WP-SL06D Water Closet Flushometer Drop-In Kit is an internal parts kit for Sloan FlowRite flushometer-equipped water closets. The SL06D family is represented by the A-37A designation (Sloan 3301037), identifying it as a 1.50 GPF inside parts kit. As a drop-in solution, it installs inside the flushometer body to refresh the valve's internal components without removing the fixture, preserving flush performance for 1.5 GPF closet installations. The WP-series naming indicates it is the Water Closet variant of the FlowRite line, designed specifically for closet applications, and it targets maintenance tasks in commercial restrooms where a 1.50 GPF flush is specified. The kit is commonly used in office buildings, schools, and other public facilities to restore reliable flush operation while maintaining the efficiency characteristics associated with 1.5 GPF. When replacing, cross-check the A-37A (3301037) designation with your fixture's flushometer family to confirm compatibility and avoid incorrect parts.
