What is the minimum required distance a plumbing vent must be from a window?

The minimum required distance a plumbing vent must be from a window is 10 feet. This requirement is in place primarily to prevent any potential odors or gases from the plumbing system from entering living spaces, ensuring both health and comfort. Proper venting plays a crucial role in maintaining air quality indoors, as it helps to facilitate the proper flow of air in the drainage system and prevents sewer gases from accumulating in the home. Therefore, establishing a distance of 10 feet from windows serves to mitigate these concerns and adheres to health and safety codes in plumbing.
