    I'm planning to install a self-priming electric pump (with pressure regulator & expansion vessel) to suck water up from a well (10foot down or so). However, given occasional long periods of non-use, I'm wondering if there's a possibility of the pump passing any amount of air, e.g. into the expansion vessel (bottom entry above the pump).

    Does one usually need a deaerator (preceding the expansion vessel), or is that taken care of by the self-priming pump?

    Not needed , I can't see that it would matter if air went in there.
