When the player arrives at the flush line puzzle, the fresh water pipe flush valve can be closed without opening the district supply line valve first, and it opens like a func_rot_button instead of a momentary_rot_button (hitting use briefly will make it open all the way). After it has closed once in this way it behaves correctly.
