## Questions & Answers

**Q: Can I get this in white**
A: I would have liked white too but didn't see any available.

**Q: Will this work at the end of a drain pipe past the btm of a downspout?**
A: Yes yet it doesn't retract , it just lays there. If its windy it will fly around so i zip tie mine to the downspout.

**Q: Can you cut it?**
A: Yes.  It is just thick plastic material.

**Q: Can you place to go around corners if you unroll yourself?**
A: Probably, if it is not a tight corner. I think a sharp bend would make the water back-up. It is just a thin plastic tube.
