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.\u003c\/p\u003e\u003cp\u003eThis 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.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1.28 gpf flush volume meets water efficiency requirements for water closets\u003c\/li\u003e\n\u003cli\u003eBattery-powered sensor operation with an estimated 6-year battery life\u003c\/li\u003e\n\u003cli\u003eDiaphragm valve with semi-red brass body for durability in commercial service\u003c\/li\u003e\n\u003cli\u003eTop spud fixture connection for straightforward retrofit installation\u003c\/li\u003e\n\u003cli\u003ePolished chrome finish suits standard commercial restroom aesthetics\u003c\/li\u003e\n\u003cli\u003eADA compliant, cUPC certified, BAA compliant, and satisfies LEED, BREEAM, and Green Globes water credits\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned 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.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation 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.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlush Volume\u003c\/strong\u003e: 1.28 gpf (4.8 Lpf)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Polished Chrome\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower Type\u003c\/strong\u003e: Battery\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBattery Life\u003c\/strong\u003e: 6 years\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eValve Type\u003c\/strong\u003e: Diaphragm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eValve Body Material\u003c\/strong\u003e: Semi-red Brass\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFixture Type\u003c\/strong\u003e: Water Closet\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFixture Connection\u003c\/strong\u003e: Top Spud\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOperating Pressure (Flowing)\u003c\/strong\u003e: 15 to 80 psi (103 to 552 kPa)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlush Type\u003c\/strong\u003e: Single Flush\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 3.39 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCertifications\u003c\/strong\u003e: ADA Compliant, BAA Compliant, BREEAM Water Credit, cUPC Certified, cUPC Green Certified, Green Globes Water Credit, Satisfies LEED Credits\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SLOAN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: RESS-C-1.28\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SLOAN","offers":[{"title":"Default Title","offer_id":68634261651762,"sku":"RESS-C-1.28","price":505.23,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ab79c14bf7084972298de9933eef8ca4.webp?v=1794374442","url":"https:\/\/voomisupply.com\/products\/sloan-ress-c-1-28-g2-optima-plus-flushometer-1-28-gpf","provider":"Voomi Supply","version":"1.0","type":"link"}
