The KA flange in the drain, visible when looking down at the sink, is
still in very good condition. It's the mounting flange under the sink
that is all rusty. Upon closer inspection, when looking up at the sink
from below, it seems the sink itself, all around the circumference of
the drain, may be corroded. We'll have to remove the disposal to see for
sure.

If I understand the gist of your replies, you both agree that it's
material, not workmanship? Do I have a basis from griping with the company
that installed it? Did they choose a cheapo flange?

Are you talking about the visible flange in the sink opening? Does the
flange have the KA logo embossed on it? Mine does. It has been in place
for about 18 years and it is perfect condition. I'm not sure just what you
have as the KA has nothing that would rust out. If the installer did
something else, you have a gripe against him.
