What is the proper way to connect two pvc pipes if you at unable to twist either pipe?

Hi GB...

If I understand you correctly here, you just need to prime the pipe and fittings and then cement them and join all together. Ideally, you would give the fitting/pipe a 1/4 turn, but if you can't then you can't and should be just fine as long as you primed and cemented everything well.

Otherwise, if for some reason that doesn't sit well with you then you could always join the pipe pieces using PVC x PVC SHIELDED CLAMPS... see image.

Let me know if that works out...
