Pop-Up Drainage Emitter with 4" Elbow
The pop-up drainage emitter is the termination point for your underground drainage system. It stays flush with the ground when inactive and pops open automatically when water pressure builds in the pipe, discharging runoff away from structures, hardscape, and landscaping. Once the flow stops, it closes back down — keeping debris, pests, and lawn equipment out of the pipe. The included 4" elbow connects directly to your corrugated or N12 pipe run, making installation straightforward.
This is the clean, professional finish to any gutter or surface drainage system. It eliminates the old-school approach of just daylighting an open pipe in the yard, which invites clogs, critters, and looks sloppy. Contractors and homeowners both appreciate the low-profile appearance and hands-free operation.

HOW TO USE
Installation Tips
- Install at the lowest point of the pipe run where water can discharge safely — away from foundations, patios, and neighboring properties
- Set the emitter top flush with finished grade for mowing clearance
- Ensure minimum 1% slope from collection point to emitter for reliable gravity flow
- Periodically check the lid for debris buildup — leaves or mulch can block the opening
- For high-volume systems, use multiple emitters rather than one overloaded outlet
