I'm replacing a toilet and noticed that the flange is about 1/8" below the level of the tile, and my understanding is it should be above the flooring. It also seems that either the flange or the tile isn't perfectly level. It's lasted 14 years with just the wax ring but I wanted to get some pros and cons of that vs adding a spacer. I'm a novice at this and my wife wants me to just call a plumber. Thanks.
