My toilet never leaks on the floor, but last week the pipe to our
septic froze. I had a plumber fix the clog and thats solved. But
when it was backed up, a small amount of water was leaking where the
toilet joins the floor. That tells me the wax ring is leaking.
But, is it normal for the wax ring to leak when the sewer backs up?
