Hi,
i am trying to replace a broken/rusted flange. and i think it is
made of plastic. It is glued to the a PVC pipe (black) - which is the
sewer pipe. what are the methods to remove the old flange ? i can see if
i can put in a hack saw and saw the flange - but then i will be taking
out part of the sewer pipe with it too.. are there any other methods ??

thanks,
