How can improper venting affect drainage systems?

Improper venting can significantly affect the performance of drainage systems, primarily resulting in slow drainage. Venting is essential for equalizing pressure within the drainage system, allowing water to flow freely through the pipes. When the venting is inadequate or blocked, it creates a vacuum or negative pressure that impedes the flow of water. This disruption can lead to slow drainage because the water is unable to move swiftly through the pipes due to this pressure imbalance.

In addition to slow drainage, improper venting can also lead to other issues like the formation of traps or siphons that can fail to maintain the necessary water seal, allowing sewer gases to enter living spaces. Thus, the importance of proper venting is critical for the effective operation of drainage systems.
