NDS 3 & 4 Inch Pop-up Drainage Emitter 420C

Allows water to be diverted and released to water-safe areas away from structures, erosion-prone landscapes, and poor drainage areas. The special patented design allows the emitter to open with a negligible amount of pressure. 

As water pressure builds, the cap pops up as high as 1 in., disperses water at up to 56 GPM, and closes once the flow diminishes. Cap remains closed when not in use to prevent debris and rodents from entering and potentially clogging the drainage system. The flat profile design blends discreetly into the surrounding landscape. Rounded contours on interior edges reduce the potential for clogging and internal ribs provide durability and strength. Flange design prevents turf overgrowth.

The Pop-Up Drainage Emitter connects to 3 in. and 4 in. sewer and drain fittings which connect to sewer and drain pipe and triple-wall pipe; connects to other pipe types using appropriate adapters. Cap and cover made of high-density polyethylene (HDPE). 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.
