I want to set up an irrigation system that runs from a hose outlet on the side of our house. Part of it is going to be permanent and above-ground. We live in Minnesota, so it gets cold in winter and hot in summer. Naturally we're not going to use irrigation in winter, and can let the pipes drain. What kinds of pipe/tubing are both UV-resistant and cold/hot resistant?
From what I've seen:
- C/PVC is UV-resistant but too brittle in cold
- PEX is cold-resistant but not UV-resistant
- Polyethylene is resistant to UV and cold? But I'm confused because PEX is made with polyethylene.
