This new release of the Stanwell urinal features the same streamlined style and dimensions as the original but with enhancements including a more water-efficient flush rate of 0.5 to 1.0 gpf. The inlet spud has been reduced from 1-1/4" to the industry standard 3/4". Rough-in and wall-print dimensions remain the same as the K-4972 Stanwell, and the powerful blow-out action flushes like a bowl and offers quiet performance. Blowout flush action. 3/4" rear spud. Uses 0.5 to 1.0 gallons per flush. Will replace K-4972-ER Stanwell urinal. Vitreous china.
