Sloan RESS-C-1.28 G2 Optima Plus Flushometer 1.28 Gpf

Product Description

The SLOAN RESS-C-1.28 is a battery-powered electronic flushometer valve designed for water closet applications requiring a hands-free, sensor-activated flush. Part of the G2 Optima Plus exposed retrofit series, this unit delivers a single flush volume of 1.28 gallons per flush (gpf) through a top spud fixture connection. The diaphragm-style valve body is constructed from semi-red brass and finished in polished chrome. Operating pressure ranges from 15 to 80 psi, making it compatible with a wide range of municipal supply pressures. Licensed plumbers and commercial facility technicians install this valve as a retrofit upgrade on existing exposed flushometer rough-in.

This flushometer is intended for commercial and institutional restroom environments where touchless operation reduces cross-contamination risk and supports water conservation goals. The 1.28 gpf flush rate meets current water efficiency standards for toilet fixtures. The battery-powered sensor eliminates the need for hardwired low-voltage connections, simplifying the retrofit process on existing water closet rough-ins. It is suited for high-traffic restrooms in office buildings, schools, healthcare facilities, and hospitality settings where reliable, code-compliant automatic flushing is required.

Compatibility

Designed as an exposed-mount sensor flushometer retrofit for commercial water closet fixtures with a top spud connection and supply pressures between 15 and 80 psi.

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and IPC requirements. Shut off the water supply and relieve line pressure before removing the existing flushometer or valve components. Do not overtighten spud couplings or slip-joint fittings, as brass valve bodies can be damaged by excessive force. Verify operating pressure at the supply stop falls within the 15 to 80 psi range before commissioning the valve.
