Understanding PVC Pipe Glue

Before we dive into the removal methods, it’s crucial to understand what we’re dealing with. PVC pipe glue, also known as PVC cement or solvent cement, is a strong adhesive specifically designed to create a watertight seal between PVC pipes and fittings. This glue works by chemically melting the surface of the PVC, allowing the pieces to fuse together as the solvent evaporates.

Key characteristics of PVC pipe glue:

• Fast-acting and quick-drying
• Creates a permanent bond
• Resistant to water, chemicals, and temperature changes
• Expands slightly as it cures, filling gaps for a tight seal

Understanding these properties helps us appreciate why removing PVC pipe glue can be challenging and why specific techniques are necessary for successful removal.
