Hello, I am replacing a broken toilet flange and have already removed the old flange. The bathroom flooring is an engineered wood floor. When the floor was installed they ran it all the way to the sewer pipe except for one side (opposite where the flange was cracked). The flange bolts are uneven because of this. One sits on the subfloor and the other on top of the wood floor. I presume that is why the old flange cracked because of the play between the uneven bolts. I need help in determining a solution. Should I cut the the wood floor away so the new flange secures directly to the subfloor? Will I need to add a spacer or double wax ring at that point since the flange will sit below the finished floor? The wood is 3/8" thick. Thanks in advance for the help.
