What is a potential consequence of trap seepage?

Trap seepage refers to the leakage of water from a plumbing trap, which is designed to retain a certain amount of water to prevent sewer gases from entering the living space. When trap seepage occurs, it compromises this water seal, allowing sewer gases to escape into the environment.

The presence of these gases can create health hazards, unpleasant odors, and can lead to more significant plumbing issues if not addressed. The trap's main function is to block these gases from passing through, so when seepage happens, it directly undermines this protective barrier.

In contrast, other potential issues like increased water pressure or blocked pipes are not direct consequences of trap seepage. Although water contamination is a serious concern in plumbing, it is typically more related to backflow issues or failures in the system that introduce contaminants into the water supply rather than resulting directly from trap seepage. The direct link between trap seepage and the escape of sewer gases clarifies why this is the correct answer.
