One more thing...you mentioned you had weak vacuum to the water valve mounted on the engine. Either one of the lines from the T which goes inside the car to the mini control valve is not connected or leaking...or the one that goes to the water valve is not connected, or leaking...if all is right you have a bit of vacuum...enough to close the water valve.  Doesn't take much.  If you hve a vacuum gauge, connect it to the line giong to the water valve, and check what you get when the control lever is moved from one end of its travel to the other. Off should be no vacuum at all and on shoudl produce a couple of pounds.  You can also take a hand operated vacuum pump and connect directly to the water valve,, a few pumps and it should operate...if not, it is defective.  Hope all this helps...didn't mean to go into such detail...but that is the way I would tell you if I was there in your shop with you !!!!!
Good luck and let us know what you find.
