422G Pop-Up Drainage Emitter with Elbow fits 4-Inch Sewer and Drain Pipe, Works with Drainage Systems Including Catch Basins, Green

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

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.

The black pipe portion of the emitter is solidly built. The green pop up base itself feels a little flimsy. It doesn't seem to lock onto the pipe at all but perhaps that's by design. The emitter itself does get clogged with leaves which prevents it from closing all the way so it does require some maintenance. I wish the vertical pipe portion below the emitter extended further down before the 90 degree angle. Hard for turf to grow around that part as there is no room for soil below grass roots. This has caused a portion of the grass to brown and die around it.

I had a pop-up just like this one and I hit mine with the lawn mower which ripped the pop-up feature out of the ring and damaged internal plastic parts. I found this unit at a reduced price which did not cost but about two to four dollars more than the NDS universal replacement pop-up. Technically, a 4" NDS cap with pop-up or the universal cap with pop-up both fit the NDS 4 inch elbow. However, this model is 6.5" across with a full 4" pop-up whereas the universal model which doesn't come with an elbow is only 6" across and the pop-up is only 3 3/8" wide. Wider is better because it allows more room for drainage in the event leaves clog the line. The wider cap also looks a bit better than the smaller universal model although either model has a tendency to fade. This isn't too hard to install but naturally you have to dig a little if you replace the elbow as well. I like to install a stainless steel screw where the elbow attaches to the drain line to prevent slippage which requires a drill. The cap can be pulled off the elbow for easier removal of leaves.

4 inch 90° elbow drain works perfect.

Good, look nice

Perfect answer to keeping lawn draining properly

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.

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.

Works great

careful with lawn mower. suction from blade lifts pop up and is shredded
