NDS 420C Pop-Up Drainage Emitter for 3-Inch & 4-Inch Fittings - Green Plastic

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
• 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
• Sure! Please provide the text or lines you would like me to modify, and I'll help you rephrase them to avoid duplication while maintaining their meaning.
• Outside flange prevents grass from growing over the cover
• 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
• Comes with one Pop-Up Drainage Emitter . Hassle-free limited lifetime warranty guarantees the NDS product is free from defects—or we’ll replace it
