I have the "backscatter vacuum" system on my S&S housing, there is also a bit of play on it also. Been using it for a few years now and now issue. It is solid when under pressure. Give Aquatica a shout to be sure, they're normally very quick to respond. If its holding vacuum over night and doesn't lose vacuum by wiggling it as okuma suggested Id think your good to go. Might want to test dive it without camera.
