What is a key consideration to keep in mind when repairing cast-iron pipes?

In the context of repairing cast-iron pipes, minimizing the disturbance of the pipe is crucial for several reasons. Cast-iron pipes, while durable, can be brittle, and excessive disturbance can lead to cracks or further damage. When repairs are made, the integrity of the surrounding soil and the pipe itself should be maintained to avoid inadvertently compromising the pipe’s structural integrity.

Additionally, minimizing disruption helps in maintaining the overall stability of the system. It also reduces the likelihood of introducing unnecessary stress to the pipe, which can lead to future leaks or failures. Ensuring the surrounding environment is preserved as much as possible allows for a more stable repair and prolongs the life of the pipe.

The other options suggest actions that would either exacerbate the condition of the pipe or involve materials that are not compatible with cast-iron, which could lead to more significant issues down the line.
