The reason why the ЮM3 Water pump does not get water may be incorrectly installed by the user. The correct installation and use method is that the suction pipe of ЮM3 Water pump needs to be equipped with a bottom valve at the bottom of the pool. Before starting, the whole pump body and water inlet pipe should be filled with water, and the outlet valve should be closed before starting. After starting the pump, the outlet valve should open slowly.
