Sloan Valve’s new guidebook for its hybrid urinals combines a multi-patented cartridge with Falcon Waterfree technology and Jetrinse Solution technology to keep urinals and drain lines clean, hygienic, odor-free and clog-free. Water is supplied to the back of the housing through a solenoid valve and air-gap device. The water is directed through a nozzle against the cartridge, powerfully redirecting it down the housing and drain line. The solenoid valve is programmed to inject about 1 gal. of water every 72 hours. The cartridge uses 20% less material than previous models, making it even more environmentally friendly.
