As I’m building a bog, I need to transition from underground piping to above ground and up and over the side wall of my bog. Don’t want to use standard pvc piping as I’m guessing that’d be ripe for cracking.....from research I understand flexible schedule 40 pvc is the gold standard. But....I have a heck of a time finding it locally. I don’t see it at Menards or HD or Lowe’s. If you use this stuff, where do you source it? I’d just order it online, but I have time off next weekend and wanted to do this project then and Amazon is wholly unreliable right now for delivery time frames. Or am I foolish and should just use the inexpensive white pvc? Maybe I could create a union at the ground next to the bog so I can remove the pipe and more easily drain the water in the fall? Does any of that make sense?
