What is a potential consequence of old tailpieces and traps made of soft brass when disturbed?

Old tailpieces and traps made of soft brass are often susceptible to degradation over time. When they are disturbed, such as during maintenance or inspection, the physical integrity of the material can be compromised due to factors like corrosion, fatigue, or stress. Soft brass is particularly prone to becoming brittle, especially if it has been exposed to moisture or a corrosive environment, which means that even minor disturbances can result in these components breaking into pieces.

This potential for breaking is significant because it can lead to complete failure of the plumbing system that relies on these components, resulting in water damage or the need for costly repairs. While other issues like corrosion, leaks, or expansion can occur as well, the immediate concern when old, soft brass fixtures are disturbed is the risk of fracturing, making this the most relevant consequence in this situation.
