The first product development project I worked on at Sloan was to create a high efficiency flush valve capable of reliably flushing a pint of water into a urinal. Similar efforts were done using electronic solenoids, however there was a demand for a manual, non‐battery‐operated product. After working with my mentor, John Wilson, we came up with this design for a modified version of an existing critical part in the flush valve assembly in order to regulate the flow. It has received great success since being introduced and has allowed Sloan to branch off into the ceramics market, starting with high efficiency urinals.
