Pumps are generally not considered a primary source of piping leaks when compared to other components listed. While pumps can occasionally develop leaks due to wear or failure of internal seals, they are designed to handle fluid movement effectively, and the actual piping systems surrounding them usually bear a greater risk of leaking.

In contrast, valves are frequent leak points because they have moving parts and seals that can degrade over time. Bolted connections also present a vulnerability as they can loosen or corrode, leading to gaps where fluid can escape. Integral attachments, such as flanges or fittings, may suffer from issues related to alignment or thermal expansion, also resulting in leaks.

Therefore, while all components in a piping system can, in theory, develop leaks, pumps are less commonly identified as typical leak sources compared to valves, bolted connections, and integral attachments. This differentiation is important in the context of maintenance and inspection strategies for preventing and addressing leaks.
