It sounds like your hoses are not connected as per the diagram. If they are, then the only way I can see any other connection between vacuum and water to manifold is if there is some kind of leak inside the water jar and water is able to get into the vacuum side of the power piston. The only normally vacuum hose that could possibly get water aside from that would be the one from valve to the co-ordinator cylinder on wiper motor and then ONLY if there was a blown diaphragm or hole in the co-ordinator valve, otherwise the vacuum and water are totally separate.

If there were a blockage, the water could not escape and the co-ordinator (assuming it is functional) would keep the wipers moving until the pressure finally bled off and the co-ordinator valve released vacuum to cylinder and allowed things to stop.
