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.

Installs easily and functions as advertised. Wishing that the emitted cover removed more easily to aid clean-out.

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 Amazon 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.

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.

Put a new yard in! I have two down spouts draining through this pop up drain and it does a great job. Out of site and hard to see in the new yard.

Simple to install, bugs don't get in and does not seem to smell. We had 2 very large rainfalls and it performed well, did not pop up all the way but worked as advertised. It is good quality product, much better than Home Depot sells. Price is little high, but I'm expecting to have this for years.
