NDS 422G Pop-Up Drainage Emitter with Elbow (4 Inch)

Every drainage system needs a point of release to prevent back-up issues. Use the Pop-Up Drainage Emitter to safely discharge collected water away from structures, erosion-prone landscapes, and poor drainage areas.

The Pop-Up Drainage Emitter with Elbow connects to 4 inch sewer and drain pipes. When water pressure builds, the cover “pops up” as high as 1 in. to release water at up to 40 GPM. Cover closes automatically once the flow diminishes. Cover is made of polyethylene and the elbow is made of polyvinyl chloride.
