Submersible Well Pumps

Submersible well pumps help keep water flowing from your well to the house, barn and other spots around your property. Installed below the water level, these electric water pumps push water up through the well pipe and into your water system, supplying everyday needs such as filling livestock water troughs, washing equipment and running household fixtures. A deep well submersible pump can serve wells beyond the practical suction range of an aboveground shallow well pump, but choosing the right setup takes more than checking well depth alone. Well casing diameter, the pumping water level and the amount of water your property needs all factor into pump selection. Flow rate, measured in gallons per minute, should match your expected demand without exceeding the well’s ability to replenish water. Think through how many faucets, stock tanks or irrigation outlets may run at once so your submersible well pump can support the chores ahead. Matching a submersible well pump to your water system also means looking at total dynamic head—the combination of vertical lift, required delivery pressure and friction losses as water moves through pipes and fittings. Pump horsepower matters, but the pump’s performance curve tells you whether it can deliver the needed flow at that head. Check voltage, wiring requirements and compatibility with your pressure tank, pressure switch or pump controller before choosing a replacement well pump. Depending on the motor design, a separate control box may be necessary, and dry-run protection can help guard against damage if the water level drops too low. For drinking water service, check that the pump and other system components meet applicable potable water requirements. A qualified well contractor can evaluate well conditions, size the pump and handle installation according to local requirements. Once your system is running, watch for changes in water pressure, frequent cycling or air at the faucet, since those signs can point to pump, tank or well problems that need attention.
