Would appreciate some guidance on closet flanges:
1. I have a Sioux Chief SS flange that goes into a 3" pipe. The PVC pipe comes up through a tiled floor with an almost perfectly sized hole for the pipe. But....the closet flange has a ridge at the bottom, inside the SS metal ring, that prevents it going through this hole and leaving the metal part on the finished floor. Should I plan to make the hole wider, which will generate copious amounts of dust and weaken the tile, or can I shim the metal part of the flange? I'm tempted to ask a metal fabricator to make a ring that goes under the metal ring in the flange. Parenthetically, why is something that sells in the hundreds of thousands if not millions so badly designed?
2. I have heard someone claim that when gluing plastic part of flange to (PVC) pipe, one should not prime it, I guess to make it possible to remove the flange later. The flange goes into rather than over the pipe, but even so, how advisable is this?
3. In a different situation, I'm installing a flange on a basement floor. I know from experience the concrete slab will not take tapcon screws, and I doubt the tiles would survive trying to screw into them, so I am planning on 1/4" or 5/16" anchor bolts (about 3" long). Is that SOP, or will I have problems with the toilet sitting on the nuts on the anchor bolts? The toilet is a Cadet Pro (for the triangular tank in a tight corner).
Thanks for any help.
