Mine has a check valve on the vertical pipe. The check valve has two ferncos (rubber boots) on each side and they are fastened to the pipe with hose clamps on each end. If you don't have that set-up then you could cut the vertical pipe and put a coupling in when re-installing. (You would need a small can of glue and primer.) If you can unscrew the pipe from the pump, then you would just need some pipe dope on the male threads of your male adapter that screws into the pump.
If you have city water, you can have an emergency backup device put on that uses the pressure of the city water in case your pump would ever go out.
