The job is already done but the inspector was kinda upset that I didn't use expansion fittings on my 200ft underground PVC run. The reason why I didn't use any is because pipe is like 2-3ft underground and temp changes are minimal there (I am not even sure if those expansions work underground) and manufacturer specs say that in general it's not needed underground as well. Inspector said there is earth movement and that's why they are needed, not because temp changes. But anyway, the main reason why I didn't install them because I used direct burial cable and PVC was only used for further protection. What do you think, expansions needed or not?
The other questions is this... When pipe emerges from ground and within like a foot or less goes straight inside the building with a 90, do you need expansion is this case?
