What is the purpose of a torque arrestor?
The main function of a torque arrestor is to prevent the motor start-up torque from banging the pump against the side of the well casing. A pump that is hanging from plastic pipe will most likely move around, colliding with the well casing, resulting in damage to the pump, pump cable and piping.
How deep should a submersible pump be in a well?
Well depth plays a role in pump placement. Pumps should never be set directly at the bottom of a well. It is usually best to place the pump 10 to 20 feet up from the bottom of the well.
Is there a check valve in a well pump?
A check valve is a valve that is used to prevent backflow in a piping system. Many well pumps have built-in check valves. Even if a pump does have a built-in check valve, we recommend that a check valve be installed in the discharge line within 25 feet of the pump and below the draw down level of the water supply.
Where does the torque arrestor go?
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. .
What type of pipe is used for water wells?
PVC and Poly pipe will hold up very well in harsh water conditions. When it comes to installation, Galvanized and PVC pipe are simple, predictable, easy to install, and easy to service. PVC pipe is also lightweight.
How do you install a torque arrestor?
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.
How far off the bottom of a well should the foot valve be?
Install the check valve vertically with the arrow pointing upwards and no deeper than 25 feet from the pump inlet. The foot valve should be suspended around 4 feet from the bottom of the well to prevent sediment from being drawn into the system.
