Bison Pump Deep Well Pump Systems require a special tool to hold the bell-shaped end of the PVC drop pipe during installation. For this purpose, an Aluminum Installation Paddle is utilized. This tool has a slot cut just the right angle and width to match the bell shape of the PVC drop pipe. Place the paddle over the well casing with the logo on the handle facing up. Let the drop pipe slowly slide through the slot until the bell shape is resting on the Installation Paddle. Now you are ready for the next piece of Drop Pipe and Rod to be installed!
