How to Break a PVC Solvent Weld

Cut through the PVC pipe using a handsaw.

When installing PVC pipe sections together, the coupling used to join the two pipes, as well as the pipe ends, are coated with PVC solvent (known also as cement). As the solvent dries in seconds, the installation process is done quickly. The solvent actually melts the walls of the pipe and coupling, forming a bond that is as strong as any other part of the pipe. Before the cement sets, the pipes can be quickly pulled from the coupling, but after setting the joint must be cut from the pipes.

Things You'll Need

• Work gloves
• Handsaw or circular saw
• Utility knife

Instructions

1. Put on work gloves. Place one hand around the coupling and the other hand around the pipe near the coupling. Quickly twist the pipe and coupling, while also pulling them away from each other. Continue pulling and twisting until the coupling and pipe are free. However, if the solvent has dried, cut the coupling from the pipe end.

2. Locate an area on the pipe close to the coupling where there is no dried solvent. Make a straight, perpendicular cut through the PVC pipe at this point, using a handsaw or circular saw.

3. Discard the coupling. Place a utility knife blade against the inside and outside end of the cut PVC pipe, and run the blade around the rim to remove all burrs.

Tips & Warnings

• Once the burrs have been remove from the pipe end, the PVC pipe can be used again.
