Do the flame test; if you burn PVC, the flame will turn green at some point. The weight of them are different ,PVC is little heavy than PET .
Usually the PET and PVC bottles are separated by manual before they are washed by washing recycling line. Because the PET and PVC bottles' color, shape, usage are very different, it is very easy to distinguish by manual. But if the mixed PET and PVC flakes, it is very hard to separated by traditional way. But because of their color different, now they can separated by optical sorter.
If it's a PVC conduit, yes it will work. I would test on a sample first, to be certain.
For sanitary and venting, 5 psi. for 15 minutes.

PVc glue is a specialised item for gluing PVC pipe, with a primer. It MAY glue other household items, but test first and don't expect too much. It's not made for 'other items'

Most PVC glues are rated for 40 - 110F. Weld On 725 is recommended for use in colder weather . You can use standard PVC Glue but it will take 2-3 times as long to cure before you can pressure test it. The colder it is, the longer the curing time.
