DC water pumps have become more and more popular over these years due to its unique advantages. Maybe in some cases, AC pumps are a smart choice if you are only in temporary use. But for most of the time, AC pumps have many fatal flaws. I will tell you when you should choose a DC water pump from the following four aspects.
