Perimeter laterals are positioned two to four inches from the area perimeter edge. A PVC lateral line connects from the drip zone kit to the PVC supply manifold, while dripline laterals run across the zone with dripline tees. An air and vacuum relief valve is plumbed to the supply manifold at the high point as required. A flush valve is plumbed to the flush manifold at the low point, and an operation indicator is connected to the dripline near the flush valve.
