NDS - 4" Pop-Up Drainage Emitter with Elbow

The NDS 4" Pop-Up Drainage Emitter with Elbow is a reliable and efficient discharge solution for any gravity-flow drainage system. Designed to release collected stormwater from grates, catch basins, channel drains, Flo-Well units, or downspouts, this emitter diverts water to safe, erosion-free zones. The spring-loaded cap opens with water pressure and automatically closes when flow stops, preventing debris, animals, and trip hazards. Its low-profile design blends into landscaping and stays clear of mower blades, while the attached elbow fits standard 4” sewer and drain pipe for a quick, tool-free installation. Made from 100% recycled HDPE, it’s durable, sustainable, and built for long-term outdoor use.
