There are three types of well pumps, and the depth of the well will determine which type of pump you will need:
Shallow Well Pumps
As the name suggests, shallow well pumps are used in shallow wells with a depth of 25’ or less. These pumps are not submerged in the well, but are instead placed above ground and pump the water through an inlet pipe. When looking for a shallow well pump, consider one with a tank or booster. This increases the PSI of the pump, and allows for constant water pressure to your home.
Convertible Jet Well Pumps
Convertible jet well pumps are great for people with a fluctuating water table. These pumps can operate in wells with depths between 0-25’ or 25-90’ depending on the assembly. Like shallow well pumps, convertible jet well pumps are not submersible and are placed above ground in a well housing.
Deep Well Pumps
Deep well pumps are designed to operate in the deepest wells, ranging from 90-300’ deep. Often referred to as submersible well pumps, these pumps operate by being submerged into the well. Deep well pumps are available in 2-wire and 3-wire models. 3-wire models feature above ground starter controls, making maintenance much easier compared to 2-wire models.
