: The floor is cement with tile on top. There is a 4" PVC closet bend
: buried in the concrete.

: I have a 4" closet flange that I plan to cement into the closet bend
: with the flange sitting on top of the tile.

: OK so far?

: Now, for the wax ring. They come in various thicknesses
: (#1, #2, etc.) they come with and without a rubber horn and they
: come with and without a neoprene "washer" embedded inside the
: wax.

: What should I use?

: Thanks

: Bill
I use #3 no seep with horn and neopreme gasket in it. Dale's Plumbing Service Inc. LMP
