Goofed, Cut the drain pipe at floor level for a new toilet in a new bathroom on lower level cement floor. Glued in a pvc flange in and was more concerned about seating it all the way in, and forgot to pay attention to having the mounting holes in proper position to the sides. Is there a way to add a ring to correct this, or do I have to try and cut it out?

Hi Gplym...

You may be able to purchase a RED repair ring like in the picture below (minus the black plastic center like in the picture below)... should be able to find at home depot.

You may need to drill a few holes in the plastic ring and also in the concrete to anchor it properly, but with new anchors it should get the job done for you... ;)

You could also try a closet flange extension (see picture), but I would only use this if the flange you have in place now is flush with the finished floor... let me know... OK?

MARK

Is the flange turned to a position where you could use a dremmel tool and cut new slots in the plastic that is still on the flange.
This may sound foolish but it is just a thought.
