What can be a consequence of water siphoning from traps?

Siphoning occurs when the water in a trap is drawn out due to a pressure difference, often resulting from a negative pressure in the drainage system. Traps are designed to hold water and prevent sewer gases from entering living spaces by maintaining a barrier. When water is siphoned from traps, this barrier is broken, allowing sewer gases—including harmful odors and pathogens—to infiltrate the home.

This situation can create significant health risks for inhabitants, as sewer gases can contain toxic components. Therefore, the consequence of water siphoning from traps, leading to the entry of sewer gas into the living space is a critical concern in plumbing design and maintenance. Preventing siphoning is essential to ensure the safety and comfort of the home environment.

The other options—improved drainage performance, increased water pressure, and enhanced ventilation—do not accurately reflect the problem caused by siphoning. Instead, siphoning generally leads to poor drainage and potential backflow issues rather than any improvement in system performance.
