Pop-Up Drainage Emitter for 3-Inch & 4-Inch Drains, Green Plastic - Suitable for Catch Basins & Drainage Systems

About this item

• Cap, or cover, pops up as high as 1 in. once water pressure builds; closes as flow diminishes. Flat profile design reduces trip hazard posed by open drain; closed position keeps emitter flush to the ground and safe from lawn mower blades
• Outside flange prevents grass from growing over the cover
• Includes a single Pop-Up Drainage Emitter. The limited lifetime warranty provides peace of mind, ensuring the NDS product is defect-free; if not, we will replace it.
• Connects to 3 in. & 4 in. sewer and drain fittings; connects to other pipe types using appropriate adapters. Releases collected water up to 40 GPM. Supports pedestrian traffic including lawn tractors, when properly installed
• Works with a complete drainage system to release collected stormwater runoff and standing water to a discharge point before it causes costly property damage. Provides collected water a point of release at water-safe areas downstream and away from structures, erosion-prone landscapes, and poor drainage areas
