    btw, i did a little dive job today, took longer to set up than to complete but the dive took 10 minutes, that's a long time sucking on a 1/2" pipe

    Depressurize the system to check bladder type pressure tanks. Air pressure should be 2 psi below the cut-in pressure.
    An example would be a tank pressure of 28 psi on a 30-50 pressure switch.

    Oops. Sorry didn't answer the original question.

    Like Sprinkus says.

    After looking at the photo some more, if there are two intakes in the pond and one of those check valves are fouled then the one pump that is running could just be pumping water back through the other pump right back into the pond.
    In a set up like that I would install check valves on the pump outlets to prevent the above scenario from happening.
