A subsurface header and dripline assembly for a landscape irrigation system consists of a supply lateral connected to a header positioned below the finished grade and mulch layer at a specified dripline depth of twelve inches. Driplines connect to the header with equal spacing, and staples secure blank tubing headers and driplines per manufacturer specifications. Header style is chosen based on flow and layout requirements, and staples are not required on PVC headers.
