Discharge collected water that flows downstream to the Pop-Up Drainage Emitter as a point of release. As water pressure builds, the spring-loaded cap “pops up” as high as 1 in., disperses water at up to 56 GPM, then automatically retracts once the flow diminishes. Cap stays closed when not in use to prevent debris and rodents from entering and potentially clogging the drainage system. Weep hole at bottom of elbow drains out water left in pipes to prevent stagnation or freezing in cold weather. The Pop-Up Emitter with Elbow connects to 3 in. sewer and drain pipe and 3 in. triple-wall pipe for a soil-tight. fit. Cap and cover made of high-density polyethylene (HDPE); elbow is made of polyvinyl chloride (PVC) Pop-Up Drainage Emitters are part of a complete drainage system used for stormwater management. They work with pipes, catch basin drains, channel drains, trench drains, and drain grates that filter, capture, and convey excess water to drain pipes; the pipes carry the water downstream to discharge with a Pop-Up Emitter, or to percolate into the ground with a dry well or infiltration trench.

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
Small weep hole in elbow drains out any water in the pipe to prevent stagnation or freezing in cold weather
