I am in the process of moving my pool equipment about 35' to gain more room inside of my fenced area. All of my plumbing is flexible pvc so I planned to extend everything using the same thing. I have been reading and it seems that flex is not liked by many people on here. I am in Michigan so I worry about frost heave using rigid. Any suggestions or anything to look for while doing this project? Attached is a picture of the current position of the equipment. I plan to move everything to the left where the marking paint is by digging a trench between the concrete and the fence. Also I should add that my pool was installed about 3 years ago and I do have pics of most of the plumbing.
