I am in the process of renovating a bathroom. After removing the toilet I saw that the metal flange ring was completely rotted away. I removed the metal flange as it was obvious that it could not be used. I am laying a floor over the existing concrete slab that will raise the floor level about 1 inch. Pictures of my situation can be found at (it is 4x3 ABS):
- Do I put the new (wood) floor up to the waste pipe and attach a new flange to the top of the new floor? Any tips on this?
- If I should not do this and need to put a new flange flush with the slab I will need to stack wax rings? One with flange, one without?
- I've installed toilets on existing flanges in good condition but have not ever replaced a flange. Am I in over my head? If not, again tips are appreciated.
Thanks in advance Larry
