Zurn Adds 1.1 gpf Diaphragm to Industry-Leading EcoVantage® High Efficiency Toilet (HETC) System

MILWAUKEE, WI – Zurn Water, LLC introduces the latest addition to its award-winning EcoVantage® High Efficiency Toilet (HETC) Systems: the 1.1 gpf diaphragm kit for flush valve toilet systems. This makes Zurn the only manufacturer to offer a selection of both 1.1 gpf diaphragms and the previously released sensor piston flush valves.

The Zurn 1.1 gpf diaphragm bowl system is designed to maximize water savings. LEED® v4 sets the baseline water savings for a building at 20%. By utilizing the Zurn 1.1 gpf toilet system, 31% water savings can be realized over a conventional 1.6 gpf closet system.

“By developing the new 1.1 gpf diaphragm, we are able to put this in any of our standard flush valve products,” says Kevin Gannon, Finished Plumbing Products Manager, Zurn. “This allows Zurn to offer the largest breadth of low consumption flush valves in sensor and manual operation over multiple operating platforms.”

The Zurn HETC system pairs two Zurn innovations: the Zurn EZCarry® High Performance Carrier System and the Zurn EcoVantage® 1.1 gpf diaphragm Wall Bowl System.

The Zurn EZCarry carrier boasts a hydraulically-optimized design – from water supply to waste line – that greatly reduces the chance of clogging, even for low-flow 1.1 gpf systems (a common concern in the commercial sector until now).

Third-party-verified testing conducted in 2014 by Professional Service Industries, Inc. (PSI) revealed the Zurn HETC system evacuates waste more than twice as far as industry-standard 1.28 gpf systems. Bill Gauley, technical advisor to the U.S. Environmental Protection Agency’s (EPA) WaterSense® program and co-developer of the MaP® (Maximum Performance) toilet testing methodology, recently stated that Zurn may have triggered a “watershed moment” for acceptance of low-flow toilets with the introduction of the Zurn HETC System.

The newest 1.1 gpf diaphragm kit is part of the Zurn Go Blue® family of kits that last 8-10 times longer than traditional black rubber diaphragms.

In the past few years, both the Zurn HETC system and the Zurn Go Blue diaphragm kits were honored with an industry “money-saving product” award.
