Can I vent DWV through wall instead of roof?

In general, it is not advisable to vent a drainage, waste, and vent (DWV) system through a wall instead of the roof. Venting through the roof is essential for allowing sewer gases to escape and maintaining proper air pressure in the Plumbing system. However, local building codes may have specific regulations regarding venting methods, so it's crucial to consult those or a plumbing professional before making any changes.
