The Zurn AquaFlush urinal repair kit is made of chloramine-resistant thermoplastic and thermoplastic elastomers that are engineered to withstand the chemicals found in municipal water supplies. The flush valve has the ability to maintain consistent flush volumes and reduce water consumption by not exceeding the necessary flush requirements needed for proper fixture performance. With the long-lasting, chemical-resistant internal components and triple-filter clog-resistant diaphragm, the chance of wasting water due to valve failure is virtually non-existent. Urinal repair kit. Made of multicolored chloramine-resistant thermoplastic and thermoplastic elastomers. 1. 5 GPF (gallons per flush). ⚠ WARNING: Cancer and Reproductive Harm - www.
