When installing and using a water pump, it is necessary to pay attention to the position of the pump in the water. This is very important. It should be selected as much as possible in a place with plenty of water, no silt, and good water quality. It should be suspended vertically in the water and not allowed to be placed horizontally, so as to avoid getting caught in the mud or being suspended. otherwise the water output will be sharply reduced or even the water will not be pumped.
