Which method is effective for repairing small holes in metal pipes?

Using epoxy putty or pipe repair tape is a widely accepted method for effectively repairing small holes in metal pipes. This approach is advantageous because these materials can be easily applied to the affected area without the need for extensive specialized tools or skills. The epoxy putty bonds securely to the metal surface, sealing the hole and restoring structural integrity, while pipe repair tape provides a reliable temporary fix by wrapping around the damaged area to prevent leaks.

In contrast, welding the edges together is more suitable for larger or more complex repairs as it requires a higher skill level, significant preparation, and tools, making it impractical for minor holes. Replacing the entire section of pipe is a more labor-intensive and costly option that is often unnecessary for small repairs. Covering the hole with plastic wrap would not provide a durable or effective solution, as it would fail to hold up under pressure or environmental conditions, likely leading to further leaks or damage. Thus, using epoxy putty or pipe repair tape stands out as the most efficient and suitable method for minor repairs in metal pipes.
