I am replacing toilet in 35 year old bathroom.
When I took the toilet off I removed the wax ring. The wax ring sat
on a black base part that sits on the floor and goes into the
drainage. It broke and I need a new one. It seems to have two parts
with the upper part that sits on the floor and the lower part that is
like a short tub going into the drainage area. Is this a univeral
part and do I need to put any special silicone on the new one when I
put it in?
