Sloan Valve’s patent-pending WES-150 or “Velocity” cartridge utilizes technology from Falcon Waterfree Technologies. Designed and built with input from plumbers, mechanical engineers and architects, it features an anti-splash pour spout, an indicator that provides a visual signal to know when it’s time to change, and a diverter shield that improves the user’s experience. The patented odor-reducing feature works by reducing the internal surface area to not much bigger than a dime, while using 20% less material than previous cartridge models.
