Which of the following actions should be taken before patching a pipe?

When preparing to patch a pipe, it is critical to secure, clean, and smooth any rough edges. This step is essential because it ensures that the surface to which the patch will adhere is stable and free of contaminants. A secure area prevents further leaks and damage, while a clean and smooth surface allows for better adhesion of the patch material. Without this preparation, the integrity and effectiveness of the patch can be compromised, which may lead to a failed repair and the possibility of water damage or other issues in the surrounding area.

Cleaning the edges also helps to remove any rust, grime, or debris that could interfere with the bonding process. Ensuring that the surface is smooth not only enhances adhesion but also minimizes the risk of sharp edges that could cause injury or additional damage during the repair process. These steps lay a solid foundation for an effective and long-lasting repair, making them a crucial part of any damage control strategy when dealing with piping issues.
