Not actually pulling. It would still be pushing but the
top part of the system would be siphoning. This means it has
negative pressure relative to the air.

I think that putting the computer higher than the pump can push is

prime it, and that a bad

rate or have a decent thermal shutdown mechanism. You need that in case of
pump failure, anyway.
Why not simply use a standard sump pump? Most such pumps can push a 15 or
20 foot head and don't need to be primed. 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.
