The torque arrestor is used to prevent motor start up torque from thrusting the pump against the side of the well casing. Think of it as a shock absorber for your well system.

Placement: The torque arrestor should be placed 1' or 2' above the pump.

Installation: Place the torque arrestor around the drop pipe so that each half is spaced evenly.

Install the lower pipe clamp and tighten.

Install the upper pipe clamp (leave loose) and then push down on the torque arrestor to spread the center portion so it fits the inside of the casing.

Just a snug fit, do not spread it so much that it is hard to get it in the casing. Then tighten the upper clamp. The upper clamp must be as tight as possible. This will make it easier to remove the pump at a later date.
