Tools Required

Gather the necessary tools to facilitate the removal process:

• Adjustable wrench
• Screwdriver
• Pipe wrench
• Chain or hoist (for heavier pumps)
• Bucket or container (for collecting water)

Step-by-Step Removal Process

1. Isolate and Drain

• Locate the isolation valve and close it to stop water flow.
• Open the nearest tap or faucet to drain any remaining water from the system.

2. Disconnect the Discharge Line

• Use an adjustable wrench to loosen the nuts connecting the discharge line to the pump.
• Carefully remove the line and place it in a safe location.

3. Disconnect the Electrical Connection

4. Unbolt the Pump from the Base

• Use a screwdriver to remove the bolts securing the pump to the base.
• Carefully lift the pump straight up to detach it from the base.

5. Remove the Pump from the Well

• If the pump is installed in a well, use a chain or hoist to lift it out.
• Ensure that the chain or hoist is securely attached to the pump’s lifting lug.

6. Inspect and Clean

• Inspect the pump for any damage or wear.
• Use a brush or cloth to remove any dirt or debris from the pump and surrounding area.
