3-INCH ELBOW

Discharge stormwater runoff away from your property with this NDS drainage emitter. It works with various drainage systems, including catch basins and channel drains. The cap pops up to release water when pressure builds and closes when the flow diminishes, preventing debris entry. An integrated weep hole in the elbow drains pipe water to prevent freezing, and the flange design prevents grass overgrowth. Supports pedestrian traffic when installed correctly.
