Maybe this belongs in the long term section, dunno...

I'm thinking about setting up a stash of PVC pipe and fittings at my folks. Realistically, about the hardest thing I can think of to make that we would really miss is pipe. I've also been inspired by Wildman's food tube, so I've got a few designs in my head for things like a jumbo match case.

But I've never worked with the stuff.

Do I need the primer, or can I get by with just the glue? The fewer things I have to store, the better.

Do the glue and primer get funky if they are allowed to freeze? Where I have in mind to store this isn't climate controlled.

And I've been toying with a screw-in inspection plug and fitting that I picked up the other day, and it leaks. It's also reached the point where I want pliers to get it off sometimes. I know it isn't this complicated, and they aren't supposed to leak. What am I doing wrong? For a match case, this is kinda critical.
