An on-surface dripline flush point assembly is housed in a subterranean emitter box beneath finish grade and a layer of mulch. The assembly features a flush cap for easy fit compression fittings, an easy fit coupling, and a half-inch polyethylene tubing connected to a PVC exhaust header via a schedule 40 tee or elbow and barb by male fittings. The emitter box is set over a three-inch minimum depth of three-quarter-inch washed gravel and brick supports. A note requires allowing a minimum of six inches of dripline tubing in the valve box to direct flushed water outside the valve box.
