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

Q: Do they freeze up? I live in Wisconsin and worry the residual water may freeze. Thanks

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 ?

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?

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?

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.
