Raising the level of a caste iron toilet flange to the level of the floor tile.
I have a similar problem as the person in a previous post. I installed one of those twist and sets PVC flanges right on top of my old caste iron flange but the top of the twist and set is still 3/8 inch below the tile. I am wary about using a double wax ring. Can I install one of those flange extenders with the neoprene gaskets on top of the twist and set to bring it level to the floor or maybe two of them to bring it above the floor? And I have another toilet with a similar problem of the caste iron flange being way below the level of the tile. It is leaking probably because the wax ring is broken. On that toilet I have not yet installed a twist and set. Should I install a couple of flange extenders and then a twist and set on top of the two flange extenders to bring the level of the flange up to the level of the floor or a little above? On the first toilet I do not want to remove the twist and set to install the extenders under it because I think it will be too hard to remove at this point but I can certainly use that technique on the second toilet. What do you think Massplumber or anybody else out there?
