## Questions & Answers

**Q: Is this pipe perforated?**
A: The description says perforated, I did not see that when I bought 10 of them last year.  They definitely ARE perforated but I didn’t figure that out until past the warranty.  It will let a lot of water out before it gets to where you want it.  Waste of money!!!

**Q: is this pipe designed to be buried underground?**
A: I have buried mine no more than a foot below surface.  Works great.

**Q: Is this UV rated?**
A: Black drain pipe is UV resistant, but not UV proof. This will probably last 3-5 years, if not longer, in full sunlight before it becomes brittle.

**Q: How to expand video?**
A: I have expanded it only by holding it in my hands and then pulling the compressions apart. For most men it requires what I would judge as 'medium' strength and exertion. It might be difficult for women though. I hope this response helps you.
