Which repair method is considered the simplest?

The simplest repair method is the use of DC plugs. This method is straightforward and involves inserting a plug into a hole or leak to temporarily stop the flow of water or fluid. It requires minimal tools and setup, making it easy to implement quickly in emergency situations. DC plugs can be made of various materials, such as rubber or wood, designed to fit snugly into leaks, thereby creating an immediate barrier to control flooding and damage.

In contrast, other methods like a soft patch or a box patch require more detailed procedures, often needing more extensive preparation and bracing than just inserting a plug. Although effective, these methods involve additional steps and tools to ensure a proper seal. The jubilee patch, while also a valuable technique, typically involves a more complex arrangement to hold the patch in place, further distinguishing its operational complexity compared to the simplicity of using plugs.
