Another, less scientific approach, is to just close off the inlet and open an 
outlet where you can see it.  Wait until the flow stops, then add a little air. 
 If you get some more flow out, add a little more air.  Repeat until the extra 
air doesn't dispel any water.  That will still be less than it should have, but 
enough to prevent water hammer and rapid cycling.
