Eric Aune examines the practice of terminating plumbing vents through a sidewall instead of the roof, using jobsite footage from Travis Brungardt and Joe Cook to frame the discussion. He explains the rationale behind avoiding roof penetrations, especially with durable metal roofs, and outlines how sidewall venting can reduce leak risk and maintenance issues. Aune compares how different plumbing and building codes address sidewall vent terminals, emphasizing clearance requirements, vent height, and separation from windows, doors, and soffit vents to manage sewer gas exposure. He also discusses climate considerations, snow buildup, and long-term performance, grounding the conversation in practical plumbing code interpretation and real-world building conditions.
