## Overview

The NDS Emitter with Elbow is a robust drainage component designed to safely discharge stormwater runoff at up to 40 GPM. Featuring a pop-up polyethylene cover that automatically opens and closes with water pressure, it connects directly to 4-inch drain pipes without extra fittings. Built to withstand pedestrian and lawn tractor traffic, it includes a weep hole to prevent freezing and water stagnation, making it an essential upgrade for effective, low-maintenance drainage systems.

## Description

Every drainage system needs a point of release to prevent back-up issues. Use the Pop-Up Drainage Emitter to safely discharge collected water away from structures, erosion-prone landscapes, and poor drainage areas. The Pop-Up Drainage Emitter with Elbow connects to 4 in. sewer and drain pipes. When water pressure builds, the cover “pops up” as high as 1 in. to release water at up to 40 GPM. Cover closes automatically once the flow diminishes. Cover is made of polyethylene and the elbow is made of polyvinyl chloride.

Review: Installs easily and functions as advertised. Wishing that the emitted cover removed more easily to aid clean-out.
Review: Works like a charm. I went a bit further and actually built a dry-well, putting a 5' hole filled with rock under the emitter. Instead of the 90 degree elbow my emitter is installed on top of a 4" PVC T. I utilized the 90 at my downspout. My drainage now goes under my patio slab sidewalk. My hope is this takes me into colder weather to provide continued drainage below the frost, but I'm not certain how that will work in the dead of winter. Not much water flows in those months anyway. During heavy extended rainfall the pop-up just spills on the lawn anything my dry-well can't handle. Installed at ground level I can take the lawn mower right over it as advertised, worry free. I went to all the big hardware stores for any device like this and they looked at me like I had 2 heads. I found none of the chain stores in my area sold them or really knew what I was trying to build. No problem buying one here on desertcart though. So far, I'd recommend this device to anybody wanting to get rid of a troublesome downspout and drain sitting in a traffic area. A little work trenching, but no more tripping hazard.

## Features

- 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
- Elbow connects to 4 in. sewer and drain pipe, no fitting necessary; connects to other pipe types using appropriate adapters. Releases collected water up to 40 GPM. Supports pedestrian traffic including lawn tractors, when properly installed
- Pop-Up Drainage Emitter comes with elbow securely attached for an easier install. Outside flange prevents grass from growing over the cover
- Cap, or cover, pops up as high as 1 in. once water pressure builds; closes as flow diminishes. Small weep hole in elbow drains out any water in the pipe to prevent stagnation or freezing in cold weather

## Questions & Answers

**Q: Do they freeze up?  I live in Wisconsin and worry the residual water may freeze.  Thanks**
A: I have 3 of these (similar buried systems) all running down angle underground  and yes they can freeze up  (residual water at/around the pop up, “Colorado clay” stops up the little relief drain hole) although just 1 of the lines seems to show drain water backup up to the downspout during melt…anyway, for winter I pull off the 4” at the bottom of the downspouts and slip on another adapter and length of 4” downhill” that is just open at the end (Maybe there’s a better way? because yes we have 4” laying on top of ground level that can trip over etc.!

**Q: How does the water make its way to the discharge with a hole in the bottom ?**
A: The hole in the bottom is so small that the vast majority the water will be emitted from the top. The hole only allows a small amount to drain, which is important after that heavy flow has stopped.

**Q: My down spout is rectangular is there a piece to connect with that shape on one end and circular on the other?**
A: Correct. There is a rectangular piece that fits on the downspout. Then you need your hose to connect to the drainage

**Q: Anybody use this in cold weather climates. Does it freeze up?**
A: No.  Have had 2 of then for several years in NY state.  Never a problem.  However they are used as an overflo for a drain pipe.  I have no idea what happens when they are under a foot of snow.  IBut f there is running water they won't freeze.

This pop up 4 inch downspout elbow drain is made of quality materials, and it functions very well. Stop getting critters in your downspout openings or walking through your yard and stepping in a hole, or tripping over a large downspout extension. We have had them in our yard for decades and they work fantastic.
