During a rough plumbing walk, a cleanout for a long horizontal waste line is shown behind a fixed cabinet panel. What is the best correction?

Correct Answer

C) Relocate the cleanout or provide approved removable access with the required clearance.

2025 CPC 707.8 requires usable cleanout access and permits approved cover plates. Relocate the cleanout or provide approved access that preserves the required working space; an inaccessible fixed panel is unsuitable. Source: https://epubs.iapmo.org/2025/CPC/

Answer Options
A
Leave the cleanout sealed behind the fixed cabinet panel since it is seldom needed.
B
Extend the cleanout with added fittings so it terminates hidden inside the cabinet.
C
Relocate the cleanout or provide approved removable access with the required clearance.
D
Remove the cleanout entirely because the new waste line should not clog.
