NDS 422G 4" Pop Up Drainage Emitter with Elbow, Green

I installed this on the end of 4 inch corrugated pipe I attached to a downspout that I buried in order to divert rainwater from an area where it would collect during downpours. It took me all of about 3 minutes to fit it onto the end of the pipe and backfill the hole. It is very sturdy - much better quality than anything I could find locally. We have had several downpours and it works great.

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.

Excellent service e did not have to run around city looking for one.

The first thing I recommend, is to drill three small holes in the green emitter top through the black elbow pipe and secure the top to the elbow with small screws. (I didn't do this the first time and the force of the water blew the top right off the elbow.) I dug a hole around the end of the 4 inch underground gutter drainage pipe. I then placed the drainage Emitter with Elbow onto the drainage pipe and backfilled the hole with gravel; the emitter sticks up less than two inches above ground level. I used a reflective driveway marker to show it's location so no one will drive over it, since it's close to the driveway. It looks great and works as designed.

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.
