Have tried the sail switches in the flow stream, but because of the 
material I pump they just do not work.  Material is piggery effluent 
carrying all sorts of debris which is what blocks the pumps.  Appreciate 
you suggestions but sadly they do not work in this world.Thanks all the 
same.  Neil.

            <p>                 No we have to reset the pump manually as
              the usual cause is blockages in the suction.  They have to
              be removed and then reset.  The temp rise is in the pump
              and the motor is always fine after it has cooked the pump
              as usual.</p>
            <p>Thanks,  Neil.</p>
