There is a fitting. Not sure what your skimmer bottom or return has on it. I glued a threaded female attachment to the bottom of my skimmer and went from there. My return required a special part (because it is a combo light and return and has an oddball shape)Also, when we disconnect the hoses from the skimmer and return, is there something special we need to do?
Like the Jandy ball valves I've seen mentioned?I have the same type setup as you're wanting. My equipment sits against the side of the house and the plumbing is ran underground from there to the pool.
I plug my return with a 1½" PVC threaded plug. Just unscrew the eyeball fitting and screw the plug in there.
One thing I would recommend is to use real pool valves instead of ball valves from the big box store if you possibly can. You'd be surprised how much pressure drop those ball valve create.
