Lightweight and compact, this 4" (101.6mm) Grooved Commercial Riser with Test & Drain Valve reduces the number of people required for assembly and features a built-in port and connected Test and Drain valve that enables hydrostatic testing without having to drain the system. The included UL and FM approved air/water gauge has a 3 1/2-inch dial, a stainless-steel carrying case, and mounts to a three-way valve, making replacement and removal easy.
Each 4" (101.6mm) commercial riser is made from Schedule 40 A53 Steel Pipe with a powder-coated bengal-red acrylic epoxy finish. It also features a water flow switch from System Sensor with an adjustable flow rate triggering from 4 GPM to 10 GPM (15 LPM to 38 LPM). These grooved risers are designed and assembled to exceed most local, state, and national sprinkler system requirements, including NFPA 13.
