I'm struggling with an issue I've not come across before. Removed laminate floor and found rot in flooring around area of toilet and near flange (PVC with what I believe was a cast iron ring. very rusted). In order to remove the rotted flooring, I carefully cut and pried up the ring and was going to use the Oatey 2-piece replacement ring.
The ring is a touch too big and wont properly surround the pvc lip. The OD of the pvc pipe is about 4 1/2 +/-" and the ID of the replacement flange is 5".
Any ideas/thoughts? The house was built in the 1980 and all in all quality materials were used in the building of the house.
Thanks in advance.
I normally leave the old ring in place to secure the flange, and if it's rusted out, use a repair ring more like this to hold the bolts.
If you are replacing wood though, you may want to replace the entire PVC flange, this time using a stainless steel outer ring.
