Reply To: My toilet is “rocking”. Need a “gap” filler.

I would recommend you get a hold of some 5lb lead flashing and cut it into small pieces that can be used as little wedges between the floor and the bottom of your water closet. Tighten up the T-bolts carefully as you are doing this, making sure the bowl is plumb and level. The lead should not be sticking out from underneath, if it is when you run a bead of waterproof caulking around after it will look terrible. If the floor is to cushionny or the gap very large I would suggest you have a plumber lower your closet flange.
