First I tried 3/4" schedule 40 pc. It looked perfect.
Surprising it was a waste of $30. It seemingly melted, or deformed heavily in the heat. It was glued and still broke apart.
Then I tried 1 1/4" cpvc and pvc.
So far it has worked perfectly.
It has been sunned and rained on several times and seems to be faring much better. $60 in the hole because I had to do it twice. Now that I know it will work, it's all getting glued together and I'll put a screw on joint halfway in it to make takedown and storage easier.
