10 operation of pickup by the pickup 20 and the movement of the boat its path is easily followed water flows through the conduit 25 to the inlet 27 of a tee fixture 28 at the fixture 28 the water diverges half the flow pdasses through outlet 29a and through pump 30 into conduit 32 the other half passes through outlet 29b and into conduit 34 the water then flows into check valve 40 approximately one half of the flow passes through conduit 34 into valve inlet 42 while the other half of the flow passes through conduit 32 into valve inlet 44 all of the flow entering valve 40 exits the valve outlet 46 into conduit 48 and is directed into the baitwell receptacle 15 the check valve is exemplified by those available from flow rite controls ltd of grand rapids mich and described in a pending application ser no 195 810 the disclosure of which is incorporated herein by reference preferably the cross sectional area of outlet 46 is about the same or greater than the combined cross sectional area of the two valve inlets 42 and 44 this assures that there will be no significant pressure drop across the valve and potential damage to pump seals one of the novel aspects of this invention is the configuration of the piping pump and check valve it is well known in.
