   I think that putting the computer higher than the pump can push is 
the point.   If the computer's on the low-pressure side of the circuit, 
(the pump is *pulling* water through instead of *pushing* ) it would 
take a very large leak to get the system wet.  It'll pull air into the 
water lines, instead of pushing water out into the electronics.
