Engineered for performance, Zurn’s AquaVantage® Concealed Manual Diaphragm Flush Valves provide consistent and reliable water closet operation. They feature a streamlined design while providing high-level performance, unsurpassed water conservation, and long-lasting savings. Each flush valve contains a quiet chemical and clog-resistant GO BLUE® triple-filter diaphragm to keep water contaminants from clogging it. GO BLUE® parts last up to 10x longer than the competitors’ seals and gaskets reducing maintenance expenses and extending the lifespan. The Z6143AV-HET-7L-BG features a high-efficiency 1.28 gpf and a BioCare ADA-designed no-leak handle. It has a 10-inch offset flush connection, a 7-inch span between the inside of the finished wall and the flush tube, an extended 14-inch rough-in, and a back spud. AquaVantage® flush valves include a vandal-resistant control stop cover, a high-pressure vacuum breaker, and a cast wall flange with set screw. They are the high-performance solution for any new or retrofit commercial project.
