NDS® 624 Green High Density Polypropylene Pop Up Emitter with Elbow and Pipe Adapter, 6 in

NDS® pop-up drainage emitters act as the discharge point of a drainage system, opening easily when needed to allow water to flow freely from the pipe and away from structural foundations. The patented spring loaded cap opens with the hydrostatic pressure of water flowing through the drain pipe, then closes as the flow diminishes. It allows water to be diverted and released to water safe areas away from structures, erosion prone landscapes, and poor drainage areas. The NDS® pop-up drainage emitter with elbow is an easy, safe and efficient solution to any drainage needs.
