NDS 422G 4' Pop Up Drainage Emitter with Elbow, 4 Inch, Color may vary
- Works with a complete drainage system to release collected stormwater runoff and standing water to a discharge point before it causes costly property damage. Provides collected water a point of release at water-safe areas downstream and away from structures, erosion-prone landscapes, and poor drainage areas.
- Elbow connects to 4 in. sewer and drain pipe, no fitting necessary.
- connects to other pipe types using appropriate adapters. Releases collected water up to 40 GPM. Supports pedestrian traffic including lawn tractors, when properly installed.
- Pop-Up Drainage Emitter comes with elbow securely attached for an easier install. Outside flange prevents grass from growing over the cover.
- Cap, or cover, pops up as high as 1 in. once water pressure builds.
- closes as flow diminishes. Small weep hole in elbow drains out any water in the pipe to prevent stagnation or freezing in cold weather.
