Quick Answer
To install a hand pump, ensure a minimum well depth of 50 feet and a minimum static water level of 20 feet above the pump's intake. The pump column must be at least 10 feet above the water surface to prevent suction issues. A suitable well casing diameter is 6 inches.
Site Preparation
Before installing a hand pump, inspect the well site for any debris, vegetation, or obstructions that could interfere with the pump’s operation or maintenance. Clear the area around the well to ensure safe and easy access. Mark the well casing with paint or tape to identify the pump’s intake and discharge points.
Well Casing and Pump Column Installation
Install the well casing to a depth of at least 20 feet below the static water level, using a suitable pipe material such as PVC or steel. Ensure the casing is properly connected to the well screen, which should have a minimum screen length of 3 feet and a mesh size of 1/4 inch. The pump column should be installed within the well casing, with the intake point at least 10 feet above the water surface and the discharge point at least 10 feet below the water surface.
Hand Pump Installation and Testing
Install the hand pump on top of the well casing, ensuring proper alignment and secure connection to the pump column. Test the pump by applying a moderate amount of pressure to prime the system and initiate flow. Monitor the pump’s performance and make any necessary adjustments to the intake or discharge points to optimize flow rate and reduce wear on the pump components.
