One. How to remove a broken pipe joint.
1、You can purchase pipe joint extraction tools from local hardware stores. Then, insert the tool into the broken joint and rotate it clockwise to tighten it. After that, rotate it counterclockwise to remove the broken joint.

2. Prepare a pair of pliers, a chisel, and a hammer. Then, use the hammer and chisel to break apart the broken pipe joint, and subsequently use the pliers to remove the broken pipe joint.
Two. How to remove old pipe connections.
1. Generally, pipe joints are bonded using hot melt adhesive or other adhesives. Therefore, removing pipe joints can be quite difficult. If possible, avoid dismantling; however, if removal is necessary, you can cut the pipe joints using a saw and then reconnect the pipes.
2. When making cuts at the joints, it is crucial to avoid haphazard actions. The water pipes and saw blades must be aligned horizontally, and the joints should be cut smoothly. If the cut results in a rough surface, it can be smoothed out using sandpaper or by sanding the concrete surface, ensuring a smooth and even joint for the water pipes.
Three. What to do if the pipe joint is rusted?
First, apply Rust Remover to the rusted areas of the pipe joints. Allow it to sit for 10 to 20 minutes, then remove the rust. Finally, use a pair of pliers and a wrench to remove the rusted pipe joints.
