It would probably be a good idea to call Lippert to talk to a tech. Which jacks are drifting down? The two front jacks are on one circuit, the two on one side, center and rear are on another, and the other two on the other side, center and rear on on the third circuit. If the two jacks that are drifting down are on the same circuit, it may not be the jacks and may be up front at the valves that control the jacks. Good luck with getting this fixed.
