I am installing my own system and I think Sch 80 is specified but I am finding that most plumbers are using Sch 40 which seems adequate. It is difficult to find Sch 80 pipe and fittings so what do I risk with the 40?
Second concern is that I put a new submersible pump in at 200' but after the fact I am concerned about the heat shrink fittings since I have found that my plumber/friend didn't follow the directions on heating them and only heated the ends and then put liquid tape over the ends. Do I need to pull the pump back out before proceeding with the plumbing or is waterproff essential?
