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.
