Any alterations requiring more than how many feet of soil, waste, or vent piping shall be inspected?

In plumbing regulations, specific measurements are set for alterations that involve soil, waste, or vent piping to ensure that any significant changes meet safety and efficiency standards. The rationale behind requiring inspection for alterations involving more than 10 feet of piping is primarily rooted in ensuring system integrity and compliance with building codes.

When changes exceed this length, it signifies a more considerable modification that can impact the plumbing system's performance, flow, and adherence to regulations. Inspections help confirm that the work has been done correctly, addressing potential hazards such as leaks, clogs, or improper venting, which can lead to more severe issues down the line.

In summary, requiring inspections for alterations greater than 10 feet allows for better oversight and ensures that plumbing systems function safely and effectively.
