Re: Two wax toilet rings?
First, I would try to figure out the source of the ring failure. It does happen with time on any toilet, but the way you describe your situation it is a commonly recurring problem. From the sounds of it, your flange is too low and you're trying to make up the difference with a thicker wax ring.
There are two ways to go about this, set the flange at the proper height (flush with the finished floor surface ), or use a thicker wax ring. You can buy thicker rings or you can mash two rings together, even though the two ring solution is frowned upon, it is ok as long as you join the two rings completely into a single, thicker ring.
If I am correct and the flange is too low, you can purchase an insert flange that will extend a low flange to the proper height. This type of flange extension slides into the neck of the existing flange and seals off with a rubber ring. There is also a glue in type, however with the area polluted with the wax ring, I would question how well you could get it to bond. There are also "raise a ring" flange shims that bolt into place.
