What criteria must cleanouts meet for them to be effective?

For cleanouts to be effective, they must allow easy access for maintenance. This is crucial because cleanouts are designed to provide a means of clearing blockages and performing inspections within the plumbing system. If a cleanout is difficult to access or located in an inconvenient position, it may hinder maintenance efforts and reduce the overall functionality of the drainage system.

Easy access means that plumbers can quickly and efficiently address any issues, ensuring that the system remains in good working order. This access also promotes timely inspections and repairs, which can prevent larger issues from developing. The design and placement of cleanouts should, therefore, prioritize convenience and functionality to support the ongoing maintenance of the plumbing infrastructure.
