Operating Instructions
The Sloan WES 111 UPPERCUT Flushometer features an intuitive dual-flush mechanism designed for water efficiency.
Dual-Flush Operation:
- Full Flush (1.6 GPF): For solid waste, push the handle down completely and release. This initiates a full volume flush to clear the bowl effectively.

The non-hold-open handle design prevents continuous flushing, further contributing to water conservation.
