What is the maximum distance allowed from the vent connection to any future drain outlet?

The maximum distance allowed from the vent connection to any future drain outlet being 2 feet is based on plumbing code regulations that ensure proper venting and drainage. This distance is critical because it helps maintain sufficient airflow to prevent siphoning of water from traps and ensures that wastewater can flow freely without creating a vacuum that could lead to drainage issues.

Maintaining this distance is essential to the system's functionality, as allowing too much distance might result in inadequate venting, causing potential problems such as slow drainage or trapped sewer gases. The 2-foot limit acts as a guideline for plumbers designing or laying out plumbing systems, ensuring they adhere to best practices and code requirements for efficient drainage and ventilation.
