About this detail

An underground drip irrigation system is laid out within a planted area adjacent to hardscape paving. The system incorporates center-feed and end-feed PVC supply headers alongside PVC discharge headers installed twelve inches below grade. Dripline tubing rows are spaced evenly across the planted area, with a perimeter row positioned four inches inside the pavement edge. PVC lateral lines are installed at a minimum size of one and one-quarter inches and placed inside a protective sleeve when crossing pavement. A flush valve with an indicator head is installed on the discharge header, and all supply and discharge headers are positioned no more than sixteen inches from the edge of the hardscape.
