Do your switches toggle to on or off and stay in the position you push them or are they spring loaded and release after you push them? If the former, those are wired exactly like multiple light switches would be in your house using 3 way switches - or they could each be wired directly to the pump. If the latter, there is a pump controller (somewhere) which could be bad.
