I have a similar issue to Miker who posted a couple of days ago - my flange is too high now that I've re-tiled the bathroom floor. When I put my toilet back on (dry-fit without wax ring to try it out) I found it was resting on the flange and not with the perimeter of the toilet resting on the floor.
Assuming my only real fix is to lower the flange somehow, I was wondering about replacing it. The flange fits into a 4" waste pipe and is glued to the waste pipe and the flange is screwed down to the floor. I was considering cutting the flange off with a hacksaw but because I only need to lower it about 1/4 of an inch, I wanted to ask - are there any other options open? and if I try and cut it off and replace it, given the flange is glued into the waste pipe, can I simply use a flange that is for a 3" pipe and have it sitting well inside the waste pipe? (i saw a 4" to 3" "converter" flange at my hardware store).
Thanks in advance for your help.

Without being able to see your specific situation, you will have to find a closet flange that is water tight to the existing pipe whether it be compression rubber or solvent weld.


Take pictures and provide links for them on this thread.

 

Thanks for the response. I decided I didn't want to mess with the flange and so I'm focusing on raising the floor somehow. To start with, I went and bought thicker tile - 3/8" instead of the 1/4" I was planning on using. If I find that is not quite enough (should leave me with only a small gap, maybe 1/8"), then I have bought some shower pan liner material to use to "raise" the floor level about 1/8". I thought the liner folded over twice should give me that kind of thickness and I was just going to cut out the 7" hole I need for the flange. A colleague also told me to consider using a sheet of plywood and that is sounding good to me right now.
Can I ask - what makes more sense? I think the plywood would make me feel better, and I expect there are some pressure treated kinds available that would help with water resistance (although I plan to have no leaks ). I don't know what kind of thicknesses are available. I hope there is a 1/8" thickness available because I'm looking for something easy to cut and I don't want to add too much height.
Any comments appreciated!!
