In response to Re: Repair of toilet flange.
: I have an offset toilet flange made of PVC with a
: blue painted steel flange ring. I have slightly
: cracked the PVC near the metal flange in an attempt to
: cure a rocking toilet. This was done by tightening
: the nut down too much.

: I tried a flange replacement that slips over the whole
: original flange and will bolt to the concrete just fine,
: but the toilet won't fit over the new replacement
: flange.

: I assume the whole original flange can't be replaced
: right? The PVC is glued to the original discharge pipe.
: I assume that once PVC is glued, it's glued.

: Can I try to glue the crack? Could I neatly cut the
: top part of the PVC flange with a Dremel tool? Then
: clean, primer, and glue the PVC back? Would it hold?

: Then metal ring is fine. Just when I snug the nut down
: the crack in the PVC near the flange opens up, once
: again leading to a rocking toilet.

: Note that the original flange is not bolted to the
: slab foundation, just the PVC pipe. Also note that
: any attempt to bolt the flange down won't work as to
: get the offset, quite a bit of foundation was chipped
: away -- enough that there isn't much material under
: the metal flange lip.


Unless you can secure the flange solidly I don't think you'll be able to solve your rocking toilet problem. Is it possible to pour new concrete around the flange.What I would do myself would be to break the floor around the flange,dig out enough dirt to undermine the concrete. I would put toggle bolts in the holes of the flange,screw the wings on the bolts,the bolts will provide a good solid anchor for the flange. Mix the concrete and leave it rather runny,fill the entire hole and allow it to set properly. Being a plumber I would cut the pvc from the inside of the pipe with a cutting wheel, glue a coupling and new flange on.I could tell you how I would "bandaid" the old flange if you're interested.
