 How do I remove clean out caps?
Author: RichRock (FL)

Hello all!
I'm having trouble removing the clean out cap (see first 2 pics), which is sunken a bit below grade in concrete. I tied a 10" crescent wrench and a pair of channel lock "pipe pliers" but it hasn't budged. FWIW: the last 2 pics are the other 2 clean outs that I have (one pvc), which are 2" & 3" deep in concrete, respectively. Ideally, if possible, I'd like to get one tool that can remove all three...Any ideas?

Main clean out having trouble with, outside a bit below grade in concrete.



Laundry room inside house; 2" deep in concrete


PVC outside next pool 3" deep in concrete

most of us (dare i speak for others here?) spend a minute or two trying to loosen them and after that we just destroy them and replace them. i have seen too many that would not co-operate..
sawzall, hammer and chisel or whatever will work.
replace with plastic and lather up the threads with good quality lithium grease.

The one in the laundry room won't unscrew, it'll need to be cut and chiseled out, the one outside also has a low probability of unscrewing. The PVC plug will unscrew, you may need to fashion a deep socket to fit the square and it'll come right out.

"Drifting" the plug with a heavy hammer and a sharp chisel will remove the two top ones. The recessed one needs a piece of square tubing that fits over the square head.

Hammer and chisel seem to be a common theme :thumb: but how would use them, exactly, to destroy...And what is "Drifting"?

While "destroying", how careful would you be about not also destroying the top of the drain line and/or it's threads that the caps are screwed into?

Drifting is holding the chisel at a low angle against the thread and hitting it with the hammer to rotate the plug. The combination of vibration and force will usually get it moving.

sort of what my wife does to me (minus the hammer and chisel) when she wants to wake me up from a nap.
