NDS 420C Pop-Up Drainage Emitter for 3-Inch & 4-Inch Drains

About this item

• 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
• 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
• A cap or cover rises up to 1 inch when water pressure increases and closes when flow decreases. The flat profile design reduces the risk of tripping over an open drain, while the closed position keeps the emitter level with the ground to prevent damage from lawn mower blades.
• Outside flange prevents grass from growing over the cover
