Isn't the flange just a slip fit on the sewer pipe?


Some are, but you have you use one of the two-piece ones (Two "U" shaped
pieces) to replace it unless you want to start ripping the pipes apart.

I had exactly the same problem with a dowstairs toilet sitting on
ceramic tiles over concrete. The steel flange had rotted away so there
was nothing left to hold the heads of the bolts down.

I solved the problem by drilling two 1/2" diameter holes about two
inches deep at the proper bolt locations and securing two stainless
steel hex head bolts upside down in the holes with "Rockite" expanding
cement.

(There are lots of other brands of similar stuff.)

I used a strip of wood with two holes in it to keep the bolts vertical
while the cement set.

As they say down Maine, "It worked slicker than snot on a brass doorknob."
