Sloan 3301143 Diaphragm Assembly Urinal Flushometer

Product Description

The SLOAN 3301143 is a diaphragm assembly with a white insert designed for use with the Optima high-efficiency urinal flushometer. This assembly serves as the primary flow-control component inside the flushometer valve body, regulating flush volume and ensuring consistent, reliable operation cycle after cycle. Domestically manufactured, it is an OEM-style replacement part intended for installation by licensed plumbers or commercial maintenance technicians working on restroom fixture systems. The white insert is included as part of the assembly, simplifying the replacement process and restoring proper flush performance.

This diaphragm assembly is suited for commercial and institutional restroom environments where Optima high-efficiency urinal flushometers are installed. Typical applications include office buildings, schools, healthcare facilities, stadiums, and other high-traffic venues that rely on water-conserving flushometer systems. It is a direct service replacement intended to restore factory-specified flush function when the existing diaphragm shows wear, cracking, or inconsistent flush behavior.

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and the IPC. Shut off the water supply to the flushometer and relieve line pressure before disassembling the valve body. Inspect the valve seat and body for wear or debris before installing the new diaphragm assembly. Avoid overtightening the cover when reassembling, as this can distort the diaphragm and affect flush performance.
