## Questions & Answers

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