Here's mine. It's very easy to use PVC. Poconos uses auto radiator hose, but I don't know how that holds up to sunlight and UV. I use TigerFlex, which is a flexible form of PVC. In the picture below, the horizontals from the filter are PVC, and the vertical to the pump and the hose-like piece are TigerFlex. Use Schedule 40 fittings on both.

I can roll up the T/F at season's end.
