I have a 2018 X23... anybody know how to get antifreeze into the hard tanks in order to winterize the pumps? My thru-hull vents have some sort of check valve/stopper that prevents me from sticking a hose into them. Only my thru-hull vents for my ballast bags have no stopper, so I can get a hose into those ones.
I have 6 overflow vents (and 6 ballast pumps) for the whole ballast system.
