About this item

The NDS 422G-AST Pop-Up Drainage Emitter with Elbow is a high-performance solution for managing stormwater runoff in residential, commercial, and landscape applications. Designed to work seamlessly with 4-inch sewer and drain pipes or triple-wall pipes, this emitter provides a discreet, efficient, and clog-resistant way to discharge water away from structures, erosion-prone areas, and poorly drained landscapes.

With a durable high-density polyethylene (HDPE) cap and a polyvinyl chloride (PVC) elbow, the 422G-AST is built to withstand the elements while maintaining peak performance. Its pop-up cap mechanism activates under water pressure and closes when not in use—keeping debris and pests out of your drainage system.

Key Features & Benefits

💧 Automatic Water Release

As water pressure builds in the drainage system, the pop-up cap rises to release water at rates up to 56 gallons per minute (GPM). Once the flow subsides, the cap automatically closes, preventing backflow, debris entry, and rodent intrusion.

🛡️ Clog-Resistant Design

The emitter features rounded interior contours and internal ribs that reduce the risk of clogging. A weep hole at the bottom of the elbow allows residual water to drain, preventing stagnation and freezing in colder climates.

🌿 Low-Profile, Landscape-Friendly

The flat, green cap blends seamlessly into turf, mulch, or garden beds, maintaining the aesthetics of your landscape. A flanged base prevents turf overgrowth and ensures the emitter remains accessible for maintenance.

🔧 Easy Installation

The 422G-AST connects directly to 4-inch sewer and drain pipe or triple-wall pipe without the need for special tools. It’s compatible with a wide range of NDS drainage components, including catch basins, channel drains, and French drains.

🧱 Durable Construction

Cap & Cover: High-Density Polyethylene (HDPE)
