The Pop-Up Drainage Emitter discharges stormwater captured upstream by catch basins, channel drains, and other drainage solutions and carried downstream with connected drain pipe. The spring-loaded emitter cap pops up to 1 in. high to release water when pressure builds, disperses water at up to 56 GPM, then automatically retracts once flow diminishes. Cap stays closed when not in use to prevent debris and rodents from getting into the drainage system. The Pop-Up Emitter connects to 3 in. & 4 in. sewer and drain fittings which connect to sewer and drain pipe and triple-wall pipe. Cap and cover made of high-density polyethylene (HDPE)

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

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
