For every how many floors is a yoke vent required?

A yoke vent is required for every five floors in a building to ensure proper venting of the plumbing system. This is vital because it allows for the equalization of pressure within the drainage system and prevents the siphoning of water from traps, which can lead to sewer gases entering the living space.

The regulation about yoke vents specifically addresses vertical drainage systems in multi-story buildings. This ensures that there is sufficient ventilation to allow waste fluids to flow freely down the stack without hindering the system’s ability to drain efficiently. The five-floor guideline helps maintain effective waste management in taller structures, recognizing that pressure changes and air flow dynamics become more complex as the height increases.
