An on-surface dripline flush point installation is situated at finish grade. A subterranean emitter box houses the flush cap and easy fit compression fittings attached to half-inch polyethylene blank tubing. The tubing connects via barb-by-male fittings to a PVC schedule 40 tee or elbow at the exhaust header. The assembly rests on a three-inch minimum depth of three-quarter-inch washed gravel adjacent to brick pavers. A note requires a minimum of six inches of dripline tubing inside the valve box to direct flushed water outside the box.
