Pop-up drainage emitter with elbow for 4 in. drain pipe, spring loaded, green
A pop-up emitter with a built-in elbow for 4 in. pipe. Stormwater is discharged away from structures and erosion-prone landscape, and the cap closes again once flow drops.
How it works
- Spring-loaded cap pops up as high as 1 in. when pressure builds and disperses water at up to 56 GPM
- Cap stays closed when idle, keeping debris and rodents out
- Weep hole at the bottom of the elbow drains water left in the pipe, so it does not stagnate or freeze in cold weather
On the lawn
Flat profile keeps the emitter flush to the ground and cuts the trip hazard. The flange keeps grass from growing over the cover.
Connection
Connects to 4 in. sewer and drain pipe and 4 in. triple-wall pipe for a soil-tight fit. Cap and cover are HDPE; the elbow is PVC.

- 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
- Flat profile design reduces trip hazard posed by open drain; closed position keeps emitter flush to the ground and safe from lawn mower blades
- Rounded contours on interior edges reduce the potential for clogging and internal ribs provide durability and strength
