There’s only one question. What is the elevation of the collar the toilet bolts up to in relation to FF? No mention of p-trap and no confusion. Good lord! Thank God all plumbers aren’t represented here. I need to cut off the 4″ drain stub and all I’m not sure of is how high is too high above finished tile, which isn’t installed yet, can the top of the collar be and still allow the toilet to seat properly on the floor without rocking on the collar. Here’s another question for someone else. Can the top of the flange be 1/2 inch above the tile
without interfering with the toilet placement?
