ok, the entire box of fittings and hoses and junk looked pretty intimidating. I figured we would just start putting things that fit together and see what happened. The whole idea worked pretty well until we got to the ribbed hosesthat put the water into the sump...those hoses and 4 fittings, threaded on one side and smooth on the other, seem to be what needs to go together. Unfortunately, the hose ends and the pvc are the exact same size. Any ideas?
