Sloan flushometer products belong to the Commercial Plumbing Fixtures specification code, CSI code 22 42 43 and the UNSPSC code 30180000. A flushometer is a flush valve mechanism designed to flush toilets and urinals. Many present-day commercial applications use flushometers in place of standard flush valves as they are less water intensive. The flushometer is a plumbing device that does not require a storage tank filled with water for flushing. Rather, it conserves more water over time and for every flush through delivery of a metered amount of water at much higher pressure compared to that of a standard flush valve. The product systems under study include the following products.
