Question: 1 / 400

Which of the following is required of a clean out cap located in a walkway?

Shall have a countersunk plug

A clean-out cap located in a walkway must be designed to prevent any tripping hazards while also facilitating easy access for maintenance and cleaning. The requirement for a countersunk plug addresses both safety and functionality. A countersunk design ensures that the top of the clean-out is level with the walkway surface, minimizing the risk of tripping. This design feature not only enhances safety but also allows for a cleaner aesthetic and reduces the potential for debris accumulating around the clean-out.

While the other options suggest various materials or mechanisms for the clean-out cap, they do not specifically address the critical need for safety in a pedestrian walkway setting. It's essential for clean-out caps in such high-traffic areas to be streamlined to prevent accidents while still being functional for plumbing maintenance.
