Are cleanouts required in horizontal drainage pipes at intervals of not more than 100 feet?

Cleanouts in horizontal drainage pipes are indeed required at intervals not exceeding 100 feet. This requirement is established in plumbing codes to ensure that the drainage system remains accessible for maintenance, cleaning, and inspection. By having cleanouts at these intervals, plumbers can effectively address clogs or buildup within the pipes, facilitating proper flow and preventing potential blockages from causing more significant issues down the line.

This regulation emphasizes the importance of maintaining a functional drainage system and allows for efficient remediation without extensive excavation or disruption. Proper placement of cleanouts contributes to the overall health and functionality of the plumbing system, ensuring that it operates as intended. Hence, specifying intervals of no more than 100 feet is a standard that supports safe and effective plumbing practices.
