What should be done to prevent leaks in glued PVC connections?

To prevent leaks in glued PVC connections, ensuring proper cleaning and priming of the joints is essential. This process involves cleaning the surfaces that will be bonded together to remove dirt, grease, and any debris that could prevent proper adhesion. Additionally, using a primer helps to prepare the PVC surface by softening it, allowing the solvent cement to bond more effectively.

When PVC cement is applied over a properly cleaned and primed surface, it creates a strong chemical bond as the materials fuse together. This bond is key to preventing leaks, as any contaminants or inadequate preparation can lead to weak connections that may allow water to seep through. Therefore, proper preparation of the joints is critical not only for the longevity of the connection but also for ensuring the overall effectiveness of the plumbing system.

The other choices do not address the fundamental requirements for achieving a secure bond in PVC connections. Waiting a period before using the pipes, using hot glue, or over-tightening can lead to other types of failure or issues, thus emphasizing the importance of cleaning and priming.
