NDS 430 Spring Loaded Pop-Up Drainage Emitter with Elbow and Adapter for 3 in. and 4 in. Drain Pipes

Features:

• Spring-loaded cap on cover pops up as high as 1 in. once water pressure builds and closes as flow diminishes; when not in use, cap stays closed to keep debris and rodents out of drain
• Flange design prevents grass from growing over the cover
• Small weep hole in elbow drains out any water in the pipe to prevent stagnation or freezing in cold weather

Applications:
Provides a downstream point of release for water collected upstream

Install the Pop-Up Drainage Emitter at the lowest point in the drainage system; place in areas away from buildings, landscapes, and poor drainage areas

Works with a complete drainage system to release collected stormwater runoff and standing water to a discharge point before it causes costly property damage
