Proper operating pressure is critical to an efficient and effective landscape irrigation system. In many instances, however, systems run at excessive pressure - leading to water waste and sometimes poor landscape health. One method for addressing excessive operating pressure in irrigation is pressure regulating sprinkler bodies (PRB). These sprinkler bodies are designed to ensure a specific pressure output despite excessive pressure in the system.
Over the summer of 2016 the Dukes research group, at the University of Florida in Gainesville, conducted trials subjecting various PBR models from an assortment of manufacturers to a variety of pressures to gather data on pressure regulating effectiveness. This video addresses both the value of PBRs and invites you into the group's testing process.
