The RJ by Lawn Genie ¾” In-Line Valve can be installed below ground and housed in a plastic valve box which can be placed anywhere in the landscape without marring the view or disrupting maintenance activities. This rugged automatic valve has a smooth, flow-through design that provides optimum performance in potable and dirty water applications when used with a separate backflow prevention device. The RJ by Lawn Genie ¾” in-line valve features a pressure-activated double-beaded diaphragm to ensure long life and low maintenance and an external bleed to flush out dirt from the supply and lateral lines during new installations and repairs. Note: Check city or local codes to determine whether or not there are restrictions on the types of valves that can be used in your area. (.25-20 GPM flow rate; ¾” female NPT inlet and outlet)
