My concern with this is that the code mentions a "sump pump" must be on a dedicated circuit. To me, sump pump is for a whole house dewatering system in the basement. Does this (under sink pump) qualify as a sump pump by the NEC?

That is not a sump pump. If it is what I have seen in other basements
with septic systems, it only runs when you are running water in the
sink.

Well, a sump pump only runs when you are "running water" in the sump. ;-)

I say that somewhat facetiously, but is there really a difference? Both
pumps are automatic in that they only run when they need to move water
and both the sink and the sump could cause flooding if the pump didn't
run.

Why wouldn't they be treated the same as far as requiring a dedicated
circuit? Just curious.
