Plumbing code schumbing code, are they ever going to look under the toilet, I doubt it. When the house was built and they installed the light fixture over the bathroom vanity they had to take out the box for the light fixture because the builder did not put in a vanity that was sized according to print, it was smaller so the electrical box was not centered over the vanity, so take out the box install the light fixture and the fixture covered the hole in the drywall left from the box. In addition half the electrical box was in a stud cavity used for a cold air return which was visible at the electrical rough in inspection. Both code violations.

In a previous house the flue for the furnace, the sheet metal pipe, was not inserted through the chimney flue liner, it was just butted against the flue liner and not sealed with cement so any back draft caused the flue gases from the OIL furnace to blow into the concrete block wall cavities. The hole through the the block wall was cemented on the inside so it could not be seen until I converted the oil furnace to gas and had to down size the flue pipe. Another non code install by professionals.

I doubt a non wax seal will violate code. I have decided to use a wax seal anyway.
