The NDS 422G Pop-Up Drainage Emitter with Elbow provides a discreet, downstream release that moves excess water away from structures and erosion-prone areas. In wet conditions, it offers a calm, controlled discharge path, which can reduce surface pooling and wear over time. The compact, low-profile design blends with the surrounding landscape while remaining ready to perform when needed.\u003c\/p\u003e\n\u003cp\u003eDesigned to work with standard 4-inch piping, this emitter connects to 4 in sewer and drain lines and can be paired with 4 in triple-wall pipe or adapters to fit additional configurations. When water pressure builds, the cover lifts up to release flow and then closes again as levels diminish. Installed correctly, the unit sits flush or just below adjacent turf to minimize trip hazards and keep mowing lines clean.\u003c\/p\u003e\n\u003ch3\u003eKey features and materials\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eRELEASE WATER AWAY FROM PROPERTY: Redirect upstream water downstream to protect foundations and landscape.\u003c\/li\u003e\n  \u003cli\u003eHOW IT WORKS: Operates at a low point to discharge water collected upstream and help prevent back-ups.\u003c\/li\u003e\n  \u003cli\u003eINSTALLATION FLEXIBILITY: Elbow connects to 4 in. sewer and drain pipe and accepts adapters for other pipe types.\u003c\/li\u003e\n  \u003cli\u003eLOW-PROFILE OPERATION: Pop-up cover rises up to about 1 in. under pressure and sits flush when not in use.\u003c\/li\u003e\n  \u003cli\u003eALL-WEATHER DESIGN: A small weep hole in the elbow drains residual water, helping reduce stagnation and freezing risks.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eMaterial details\u003c\/h3\u003e\n\u003cp\u003eThe cover is made of durable polyethylene, while the elbow is PVC, providing a sturdy, weather-resistant connection that can withstand outdoor use across seasons.\u003c\/p\u003e\n\u003ch3\u003ePractical installation and use cases\u003c\/h3\u003e\n\u003cp\u003eIn residential setups, it works with catch basins, channel drains, trench drains, and drain grates as part of a complete drainage system.
