I am replacing a toilet in a powder room in which I did a ripout. The toilet was set on an iron flange on an iron pipe. The floor is a concrete slab, where I am laying ceramic tile. The old flange is in very good shape and solid to the floor. After I install the ceramic tile, the flange will be slightly below the tile surface. So I went out and purchased a Set-Rite flange extension kit, but I'm slightly confused. The new extender will fit fine and I'll use Tapcon screws to bolt it to the slab - so far no big deal. The instructions on the Set-Rite says to use a wax ring, which will seal the extender (and spacing ring) to the existing pipe. So now I'm good with the flange. The instructions say nothing about when I set the toilet on the flange. Should I use another wax ring on the toilet? It seems to me that if I did not, I'd not have a good seal between the toilet and the new (extended) flange. With two rings, I'd have the seal there for the new plastic adapter to the pipe AND a seal between the toilet and the adapter.
Am I on the right track. Thanks very much!! Paul
