Concrete mounted toilet flange closet bolts
Posted by Mike on June 29, 2004 at 17:16:35:
I'm changing a toilet--simple enough except after shearing the closet bolts I discover that they are set
into concrete. The cast iron toilet flange sits on a concrete slab and was installed in the early 1970's
by a master plumber. It appears that the bolts are anchored into the concrete. What am I dealing with
and how do I replace them. Are they closet bolts set in concrete or anchored into concrete anchors.
What method was popular in the early 1970's mounting a toilet flange on concrete and how best to
approach this dillema? Thanks, Mike
