NDS 420 4-inch Pop Up Drain Springloaded

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
• Flat profile design reduces trip hazard posed by open drain; closed position keeps emitter flush to the ground and safe from lawn mower blades

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
