Hi, we are completely remodeling our bathroom and are almost to the steps of installing the new toilet. When we test fit it to make sure there would be enough space between it and the vanity, the toilet rocked pretty badly. We did not have a wax ring underneath when we test fit it, but upon closer inspection, we realized that the flange was bent (or buckled) upwards, possibly from the bolt being tightened too hard when it was installed. This is the original toilet and it probably has never been taken out before. Here is our problem. I believe that the flange is PVC and is somehow attached to the black PVC soil pipe. We don't know how to take the old flange off and replace it with a new one. Most of everything that I have read online has been about repairing a broken metal flange with a repair kit. It is not broken, just buckled. We would like to replace it but are not sure how and with what. Could you shed some light on this process for us? Thank you in advance!
