Q:Is the plug 4inches firm? Or is it smaller than 4 inches and expands to fit 4 inches? I need a plug that will fit into a 3.85" hole.

Answer This Question

A: It is for a 4- inch pipe. It is wider on top so sits like a cap. It is slightly smaller at bottom and then expands to block pipe. For the price it's worth trying. Not sure if other sizes are available.

A: Yes. I would trust it there. Ive used them to block iron septic risers several times.

A: Yes, i used it to cover a clean out opening in my sanitary sewer line. The plug fit easily into the raised opening, and the wing nut was easy to turn by hand. The plug made a perfect seal and allowed me to easily remove it when necessary. Removing the plug was just as simple.
