Nds 432GRTL Pop-up Emitter 3 4 Inch Drainage

Product Description

The NDS 432GRTL is a pop-up emitter designed for use in residential and commercial subsurface drainage systems. It serves as a termination point for underground drainage pipe runs, allowing collected water to discharge freely at grade level when hydrostatic pressure builds up, then sealing shut to prevent debris, insects, and small animals from entering the pipe when flow stops. The unit is compatible with both 3-inch and 4-inch pipe connections, making it a versatile outlet for common drain line sizes used in yard drainage, downspout extensions, and French drain terminations. Installation is handled by plumbers, landscape contractors, and drainage specialists.

This pop-up emitter is suited for residential yard drainage, commercial property stormwater management, and contractor-installed subsurface drainage networks. It terminates 3-inch or 4-inch drain lines at a lawn or landscape grade surface, providing an automatic open-and-close outlet that limits standing water issues without requiring manual intervention. The dual-size compatibility reduces the need for additional adapters on many common residential and light commercial drainage installations.

Compatibility

Designed as an OEM-style replacement or new-installation outlet fitting for 3-inch and 4-inch subsurface drainage pipe systems in residential and light commercial drainage applications.

Installation Notes

Installation is typically performed by licensed plumbers or landscape drainage contractors in accordance with local stormwater and plumbing codes. The emitter should be set at or slightly above finished grade to allow unobstructed discharge and prevent backfill from blocking the valve. Confirm pipe diameter before installation to select the correct inlet port. No tools beyond standard pipe preparation equipment are required for solvent-weld or friction-fit connections depending on the pipe type used.
