Cleanouts are required on building sewers at intervals not to exceed how many feet?

In plumbing code standards, cleanouts are essential for maintaining and accessing building sewers. The requirement for cleanouts at intervals not to exceed 150 feet is based on the need to ensure that blockages can be effectively cleared, inspection is accessible, and maintenance can be performed without excessive difficulty.

This distance is commonly adopted in many plumbing codes to ensure practical access points are available throughout the sewer system. Cleanouts facilitate the removal of obstructions and allow for proper cleaning of the lines, which is crucial to maintaining the integrity and functionality of the plumbing system.

Longer intervals without cleanouts could lead to increased difficulty in addressing potential clogs and maintenance issues, which could result in costly repairs or more severe plumbing problems. Therefore, placing cleanouts at intervals of no more than 150 feet strikes a reasonable balance between practicality and maintenance needs in building sewer design.
