If you have your slits facing down, I highly recommend you put some scrap liner below the piping, the constant pounding of the water on the liner, MIGHT notice the might wear through the liner over time.
I have my slits down, because I do shut it off during the winter, the gravel does shift around so I did not want my pipe to get clogged up by the gravel.
