My cheapo solution is to run water from a garden hose over this joint while I'm vacuuming. This keeps air from getting into the system and wrecking the vacuum.

Are you sure you don't have the wrong end in the skimmer? The swivel end that's supposed to go on the vac will leak if it's on the skimmer end.
