Replace a PVC Toilet Flange
I seem to have a PVC (white) toilet flange that is not properly seated against the drain line. There is a 3/8" gap between the joint of the flange and pipe. I put plumbers epoxy in the joint a year ago and it stopped my leak. However over time the leak has found its way back.
I want to remove and replace this flange and close up the gap. It seems the sealant/glue is holding the flange pretty tight. What is the best way to tackle this? Is there a solvent or something on the market tat will allow the flange to realese or is it just going to be brute force?

Thanks in advance.

You have to get to the pipe below, cut out a section of line and re-pipe from there with a new flange. The glue is perminant once dry.

I fully agree with Marlin.
Hopefully, this toilet is over a crawlspace or basement where you can get to it. You can re-connect the new PVC pipe to the existing with either a PVC or a Fernco or a no-hub coupling.
PVC "glue" actually isn't a glue, but a type of "solvent" that chemically "welds" the PVC together. It isn't made to come apart. Ever. However, in extreme cases sometimes you can hacksaw blade the old flange in quarters and chisel it out, sand out the old pipe, and re-do it again.
Good Luck!

Thanks for the help. Unfortunately the toilet is 2nd floor just over the kitchen. I will attack it through the floor and and replace subfloor pieces and vinyl flooring.

I'd think it would be A LOT easier to put a hole in your kitchen ceiling than to start removing subfloor and vinyl flooring!!!

Unless you've got some fancy ceiling in the kitchen, just cut a square out of the drywall. You can repair it in about 15 minutes.
