This is like most well problems. The problem is underground and you won’t know what happened until you pull it up so you can see it. If it is a broken fitting as TW thinks then sch 40 pipe is not strong enough for what you are doing. If it is a glue joint as I think it is, then glue joints are not strong enough for what you are doing. Either way this is why most pump installers don’t use sch 40 to hang a pump from.
What do you mean the "Government forbids it"?
The 'it" I was referring to is air testing plastic pipe (PVC), as suggested recently in this thread. I was hunting around and found some warnings. When I said the "government", I was thinking of "big brother", I would have been more precise if I had said the "International Code Council" which concerns itself with building codes. Here is a post at their forum:

Obviously, this will take more research if you are interested. Other comments I saw suggested however that some states or municipalities have adopted some anti-air testing based on things like this from Charlotte Pipe:
