What is the maximum distance from the foundation wall to a cleanout in the house or building drain?

The maximum distance from the foundation wall to a cleanout in a house or building drain is set at 2 feet to ensure ease of access and functionality. Cleanouts are installed in plumbing systems to provide a point for maintenance, inspection, and cleaning, thus preventing blockages and potential drainage issues.

Maintaining a distance of 2 feet from the foundation wall allows for sufficient space for a plumber to safely and effectively handle the cleanout without being obstructed by the structure of the foundation. This standard promotes practical access for tools and equipment necessary for maintenance tasks such as clearing a clog or inspecting the drainage system.

Other distances would either increase the difficulty of accessing the cleanout or may not adhere to established plumbing codes, which prioritize accessibility and safety. Therefore, 2 feet strikes an appropriate balance between accessibility and structural proximity.
