💧 Stay dry, stay ahead — the smart drainage solution that pops up when you need it!
The NDS 422G Pop-Up Drainage Emitter with Elbow is a high-density polyethylene drainage solution designed to fit 4-inch sewer and drain pipes. It features a pop-up cap that opens under water pressure to discharge excess water downstream, preventing property damage and erosion. Its flush, low-profile design reduces trip hazards, while a built-in weep hole ensures pipes stay clear and freeze-free in cold weather. Ideal for professional-grade stormwater management, it integrates seamlessly with catch basins and other drainage components.

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

Pop-up drain
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.

Functional and great quality, and no more stepping in holes or tripping.
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.

Excellent product
Love these emitter drainage systems. Like any in-ground installation, it can take awhile to get it properly located, the trench dug, and the emitter properly placed. Once installed, it does an excellent job of removing rain water from our gutter downspouts and then from near our home's foundation. The only problem I've had was my own fault. The emitter had to be installed on a slight slope. I didn't get it completely flat against the sloping ground. The first time a heavy lawn mower ran over it, it broke into several pieces. I love the fact that the water comes out in 360 degrees instead of creating a stream than can cause its own problems. I also like the way the green top camoflauges the emitter in the lawn, making it almost invisible to the casual observer. I like the drain hole in the bottom for removing stagnant water. I also like the way the top lifts off to remove any leaves or other debris that may have collected in it.

The Best NDS Pop-Up For A 4 Inch Gutter Drain
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 pop-up drain works perfect
4 inch 90° elbow drain works perfect.

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.
