I pulled my toilet due to it leaking under the base and found the metal flange had rusted away. What are my options in fixing this besides lots of demo? Would one of the 2 piece repair flanges work? There is also a substantial gap between the concrete slab and the drain pipe. see bottom of pic below. This had been partially filled with silicone. Should I fill this with a bit of concrete or does it matter?
Well they won't let me post a link. Geeeze. Still, any suggestions?
