The Sloan Royal 111 Manual Closet Flushometer 1.28 GPF (3910168) is a high-performance system component engineered to deliver premium fluid distribution efficiency and reliability. Built with a heavy-duty chrome-plated cast brass housing, this unit provides exceptional durability and outstanding resistance to demanding system environments. Its low-maintenance, high-performance architecture makes it an ideal solution for high-traffic public facility applications.
As the commercial industry standard for manual flush valves, the Royal 111 features a premium dual-filtered bypass diaphragm assembly that keeps debris from clogging the functional components. This ensures a consistent, high-efficiency 1.28 GPF (4.8 LPF) flush cycle regardless of fluctuating water line pressures. Designed with a non-hold-open handle to prevent water waste, a vandal-resistant stop cap, and chloramine-resistant PERMEX synthetic rubber seals, this floor-mounted or wall-hung water closet valve delivers an exceptionally long lifecycle and absolute water-saving compliance.
