Questions about this item

How do I install the 3-inch brass cleanout plug with recessed square drive without damaging the threads?

Wrap the male NPT threads with PTFE tape, hand-tighten the plug, then use a square-drive bit in the recessed head for the final turn. Over-tightening with a large wrench on the body instead of the drive strips the soft brass threads.

Will the brass plug need replacement due to corrosion or mineral build-up in a residential drainage system?

Brass resists corrosion in typical drain service, so the plug itself rarely needs replacement. Periodic removal to clear sediment from the cleanout body is the normal maintenance; reinstall with fresh PTFE tape each time.
