5. Connect the 11/2” diameter pipe from the tank to the suction

inlet flexible connectors of the pump. The inlet threads of the

flexible connector flanges are 11/2” BSP taper female. Seal

the joints with a suitable thread-sealing compound. Alternative

pipe work entry points, for above ground pipe work, are

provided at the rear of the pump base. Push out the plastic

cover plates if required.
