This video provides a step-by-step guide on how to remove a stuck sewer plug, which is likely never touched since its installation. The process involves using pipe wrenches, heat, and/or a hacksaw to loosen the plug. If a long pipe wrench is not available, an old-fashioned steel chisel and a ball peen hammer can be used to loosen the plug.
If the plug remains stubborn, a cold chisel can be placed on one edge of the nut and tapped counterclockwise with a ball-peen hammer. Then, move to the next face and continue hammering until the plug is loose enough to turn with a wrench.
A seasoned professional shows how to remove a stuck cleanout plug using pipe wrenches, heat, and/or a hacksaw to gain access to a stubborn clog in a drain line. The two top ones can be removed by drifting the plug with a heavy hammer and a sharp chisel. The recessed one requires a piece of square tubing that fits over the plug.
Plumbers use two methods to remove the clean-out plug: cutting away the cap from the inside or fracture it with channel locks or straight pliers down to a small rim. Avoid dropping large pieces of plastic into the plug. Heat the plug up, add cold water to break the seal, then add a liquid wrench and let it soak for a bit. To remove the expansion plug, unscrew the wing nut slightly, and if the plug doesn’t come out with a little effort, you may need to resort to grabbing the stud.
In summary, this video provides a step-by-step guide on how to remove a stuck sewer plug, including using pipe wrenches, heat, and a hacksaw.

Thank you for this article! I ran over mine this evening with my mower. I didn’t know what I would do to fix it. I am a woman, so I covered the hole with a latex glove, and put a bucket with heavy blocks on top to cover it until I fix it. I did it late,so Lowes was already closed. I will pick up one tom morning. Mine looks to be the same size as yours, I hope it is easy to do like you showed. I was really worried, especially about rats or insects getting in it.
Just replaced my cap with a 3″ and had to make a collar as the pipe is 4″ diameter. This house was picked apart by the neighborhood people before I bought it. I no longer had the threaded portion left, bought a 4″ realized there were no threads at the top. So, I cut down a smoke detector mounting bracket to slip the 3″ cap and the threaded portion, used liquid nails to secure the home made collar. I let it cure overnight, really not long enough but I mixed 1 part portland cement to 2 parts sand and secured the threaded insert with the collar so it would not fall down the clean out. The rim of the home made collar sits on the black top and does not go anywhere near the clean out, sits perfectly around the 4″ pipe. Added the ultra high strength Portland concrete so they can’t pick it apart and hide their drugs down my clean out. I mean if they want to get to my drain now they can but as soon as the Portland cures I’m going to tighten the heck out of it so they need a wrench to get if off. Good times. Yes, easy fix. Great article. I was really concerned about the rats crawling down my clean out. Mountain life is a peach.
I have overgrown garden weeds and accidentally broke it. I also saw that there was garden dirt on the sewage overflow pipe. Is that bad? Or should I try to vacuum the overflow pipe ? As will get a replacement overflow cap tomorrow. Please advise about the dirt that fell into the overflow pipe. Thanks.
Hi Greg, many thanks for this article. I tried to open the cap with the same wrench which you used but seems like the cap is too tight and not opening . Also, the cap is broken in a way that wrench doesn’t fit properly to open the cap. Can you suggest some other option? Anything I can try to open the cap ?
