The sub-surface drip installation layout comprises supply and exhaust headers sized per the irrigation plan, connected to parallel dripline tubing spaced across the area perimeter. Perimeter driplines are positioned two to four inches from the edge. A remote control valve with a disc filter and pressure regulating valve feeds the system. A pressure gauge is installed at the location furthest from the start of the supply header. A line flushing valve with a gravel sump is plumbed directly to the exhaust header.
