This month, the Fundamentals of Pumped Water Systems explores figuring out residential water needs.
Once you know this information, you can determine which type of pump best serves your application — a straight centrifugal pump, a shallow well jet pump, a deep well jet pump or a submersible pump. If the water level from which you are pumping, be it a lake, storage tank or well, is 15 feet or less, you can use a straight centrifugal. If it is 20 feet or less, you can use a shallow well jet pump. If it is no more than 100 feet, a deep well jet can be used. When you have more lift than 100 feet, a submersible pump generally is the best choice, and many pump installers prefer to use submersibles for every pumping level.
