True or False: Cast-iron pipe does not require any supplemental support during repair work.

The statement that cast-iron pipe does not require any supplemental support during repair work is false. Cast-iron pipes are heavy and rigid, but they can still be vulnerable to stresses and mechanical loads during repair processes. When performing repairs, especially if the pipe is taken out of service or if there are significant modifications, it’s crucial to provide adequate support to maintain alignment and prevent any potential sagging or misalignment.

Using supplemental support, such as braces or supports, ensures that the pipe remains stable and safe throughout the repair process, reducing the risk of additional damage or leaks when the restoration is completed. This is particularly important in areas where the pipe may be under stress from surrounding soil or other environmental factors. Thus, proper support is necessary to protect the integrity of the cast-iron pipe during repairs.
