What is the minimum clearance required on cleanouts that are 2 inches or smaller?

The minimum clearance required for cleanouts that are 2 inches or smaller is indeed 12 inches. This requirement is set forth in the Massachusetts Plumbing Code to facilitate maintenance and access for cleaning and inspecting plumbing lines. A clearance of 12 inches allows a plumber to effectively use tools and equipment needed to remove the cleanout cover and attend to any potential blockages.

Providing adequate clearance is crucial because insufficient space could hinder access, making it difficult or impossible to clear any obstructions in the drainage system. By adhering to this requirement, plumbers ensure that the cleanouts meet operational standards, promoting functionality and compliance with safety practices.
