How far horizontally should a plumbing DWV vent termination be from a door or window?

The correct distance for a plumbing DWV (Drain, Waste, and Vent) vent termination from a door or window is 10 feet. This requirement is set to ensure that any odors released through the vent do not enter the building through openings where people might be present or where air is being drawn in.

By maintaining a distance of 10 feet, it minimizes the risk of nuisance odors affecting indoor air quality, ensuring a more pleasant and safe environment for occupants. Additionally, this requirement reflects considerations for proper ventilation and hygienic standards in plumbing design, promoting overall system effectiveness while adhering to building codes.

In plumbing and construction practices, following these specified distances is crucial for compliance with local codes, which often reflect best practices for public health and safety.
