My rough plumber installled a Closet Flange on a new sewer line that goes under a concrete floor(conversion of garage to bedroom). Subsequently we added tile and now the valve is approx. 1/2" low. I know I need to add spacers and I also want to change the direction the toilet faces by 45 degrees. Can I just drill some holes into the old closet Flange and tightly screw in the new, reoriented spacers?....thanks
