What is the minimum size concrete pad for a two-way cleanout on a building sewer?

The minimum size for a concrete pad around a two-way cleanout on a building sewer is 18 inches by 18 inches. This size is specified to ensure that there is adequate space for maintenance and accessibility of the cleanout, allowing for proper operation and plumbing services. The dimensions provide enough room around the cleanout for personnel and tools to fit comfortably, facilitating easy access for inspection and cleaning.

Larger pads may offer additional space, but the 18 x 18 size meets the minimum requirements set by plumbing codes. Ensuring compliance with these specifications is critical for maintaining proper sewer functionality and meeting code requirements in any installation.
