How to Remove a Pipe From Well Casing

Removing a pipe from a well casing requires careful preparation and execution to ensure safety and prevent damage to the well. Here's a step-by-step guide on how to remove a pipe from well casing:

1. Safety Precautions:

- Wear appropriate safety gear, including protective clothing, gloves, and eye protection.

- Ensure adequate ventilation in the work area to avoid inhaling harmful fumes.

2.Gather Tools and Materials:

- Adjustable wrench

- Pipe wrenches (various sizes)

- Open-ended wrench

- Hammer

- Chisel or pry bar

- Heavy-duty pliers

- Lubricant (e.g., penetrating oil)

3. Shut Off Water Supply:

- If the well has a working water pump, turn off the power or water supply to the pump.

4. Disconnect Piping:

- Disconnect any pipes that are connected to the well casing, including the discharge pipe and the drop pipe (if present).

5. Remove the Well Cap:

- Using an adjustable wrench or open-ended wrench, remove the well cap from the top of the well casing.

6. Remove the Drop Pipe:

- If present, remove the drop pipe by lifting it out of the well.

7. Loosen the Pipe Coupling:

- Locate the coupling that connects the pipe you want to remove to the well casing.

- Apply penetrating oil to the coupling to loosen any rust or corrosion.

- Use a pipe wrench to loosen the coupling by turning it counterclockwise.

8. Break the Seal:

- If the coupling is stuck and won't budge, you may need to use a hammer and chisel or a pry bar to break the seal.

- Gently tap or pry the coupling to loosen it, but be careful not to damage the threads.

9. Continue Loosening the Coupling:

- Once the seal is broken, continue using the pipe wrench to loosen the coupling fully.

10. Remove the Pipe:

- Once the coupling is completely loose, grip the pipe with a heavy-duty pair of pliers and pull it out of the well casing.

11. Clean and Inspect the Well Casing:

- Clean the threads inside the well casing to remove any debris or residue.

- Inspect the threads for damage, including stripped threads or cracks.

12. Install a New Pipe:

- If needed, install a new pipe by threading it into the well casing and securing it with a coupling.

13. Reconnect Piping:

- Reconnect any pipes that were previously disconnected, such as the discharge pipe and the drop pipe.

14. Turn on Water Supply:

- If you shut off the water supply earlier, turn it back on and test the well to make sure it's working properly.

Remember, if you encounter difficulties or are unsure about any step, it's best to seek assistance from a qualified well contractor or plumber who can safely and efficiently remove the pipe from the well casing.
