It's a long story.... I disconnected this line because I found a rusting fitting near the stand pipe and there is now a strange offset and I was thinking of putting in a piece of flex pvc instead of trying to glue up a bunch of fittings.
I'm now thinking I should try a length of Pex instead. I know how to deal with Pex - I installed Pex a number of years ago to replace all the galvanized pipe.

I try not to use flex pipe anymore than I have to just for the reason you mentioned - using cement (glue) that will hold it properly.
I have used standard PVC cement with success, but was very careful to have everything perfectly clean and completely dry. Then let it set up at least an hour before any water goes through it - longer if possible.
You also don't want any pressure on the flex pipe like any sharp bends - especially where it joins the PVC.
I have been told though if one is using a cement for it - this is the stuff to use:

In your situation - no way I would use it for a line that is under constant high pressure, as in your case.
Feel free to reply with any photos of what you are dealing with and I or others here, like Dad911, are happy to provide opinions on repair options.

I would get water service line with the proper pressure (compression) fittings. Not that expensive, rated for 250#
