I see people use the required expansion fitting
But use tight straps Impeding the expansion
I like to use minor upsized straps Wrong or right?

I havent seen many pvc straps survive outside more than four years, i think there UV rating is inaccurate

I have been at my current job 13 years now, and a run of pvc conduit that was installed before I got there is still fine. I am not at work now, and I don't recall if it is in direct sun. The climate here is very mediterranean and it never gets real hot or cold.
