Measuring, Marking, and Cutting PVC Clean-Out From the Inside

Ran over my clean-out with my lawnmower so had to cut the end of the PVC to get it straight again. Pipe is angled out of the ground so I am unable to measure and mark the outside of the pipe. Cut was not straight, but the coupler still went on. One side is way off but still has about 1/4th inch overlap over the pipe . I could cut the inside with a Dremel but how do I mark a straight line on the inside? Is gluing necessary?

If you've cut already and it's still crooked you probably will have to dig around the pipe to make sufficient room to make a square cut. An easy way is to wrap a piece of heavy paper around the pipe, then you can mark the edge. You need to have it dug out around the pipe anyhow to apply the primer and glue to attach your coupling.

Yes, glue is needed. Without it the coupling and your cap and plug will just fall off if bumped.

I can dig if I have to but thought there might be a trick without digging.

Inside couplers are available.

Paper works on the inside the same as the outside.

IMO, a crooked 1/4" cut on a 4" (or 3") pipe isn't a big deal, especially as a cleanout extension. Nothing's going to get caught in there and there's more than enough pipe for a solid connection.

I too would recommend cement/glue to permanently attach the coupler and adapter for the threaded cap.
