If a change of direction in a horizontal plane of a building sewer is made with two 45 bends, a cleanout is not necessary if the bends are how many feet apart or more?

In plumbing, particularly regarding the installation of building sewers, the Oklahoma Plumbing Code provides guidelines on how to effectively maintain access for the cleaning and inspection of drains. When two 45-degree bends are used to create a change of direction in a horizontal plane, there are specific distances that determine whether a cleanout is necessary to facilitate maintenance.

The guideline in this scenario states that if the two 45-degree bends are separated by a distance of 3 feet or more, a cleanout is not required. This rule is designed to reduce the number of cleanouts needed in a plumbing system while still allowing for adequate access for cleaning and maintenance. The rationale is that bends that are spaced adequately apart lessen the likelihood of clog formation in the area between them, making it easier to maintain the system.

This understanding emphasizes the importance of planning and executing plumbing systems in a way that minimizes potential issues, ensuring a balance between functionality and ease of maintenance in accordance with plumbing codes.
