Isolate the pump electrically, then turn off the isolating valves on both the suction and discharge side of the pump. Then contact us for advice on our pump repair service.
The pump is not rotating which is either caused by a blockage, or an electrical problem. A qualified service or pump repair engineer will be needed to rectify the problem.
Check to ensure the pump is installed correctly ie. The inflow is connected to the suction side, and outlet to the discharge side of the pump.Then ensure the pump has a flooded suction and that the water supply valves are turned on. If the pump draws liquid from below the installation, then ensure the foot valve and strainer used is air tight and not disrupting suction lift. If the pump is a new installation,then the pump will need to be bled through its bleed screw to remove any possible air locks.
