Eddy- It's possible you might still have to install an expansion fitting even if you used elbows and the like to take up the expansion/contraction but not necessarlily per code. I'd like to add to what iWire said because he knows it and just didn;t say it. What is just as important and maybe more important than we realize is that we use the supports that are designed for PVC. I'm talking about the ones that allow the conduit to slide back and forth during temperature change. So many jobs I look at the contractors use standard one hole straps and they end up having to change them.
