NDS Emitter, 7-1/2" Green High Density Polypropylene Drainage Pop-Up w/90° Elbow

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.
