The normal checkvalve in a submersible is integrated with the pump.
Some systems are installed with a second one above ground. Unless the
pump one has failed I have never understood the rationale of
installing a second one. In your case, look for a fitting in the pipe
(it will be a bit larger than the pipe) that has only the inlet/outlet
and no other connections.

In any case, it would not be the cause of the pump not delivering
water, only not holding pressure when the pump shuts off.
