I searched. The advise given was that hot water can melt small pieces of
fat which will then go down the pipes and clog up. The temperature at
which a garbage disposal unit would overheat is a hell of a lot higher
than the temperature of hot tap water. Dishwashers have a built in
garburator and they not only use hot water, they can heat it even higher
on their own.

I run hot water down my pipes on occasion but not when I run the disposal.

The manufacturers always say cold. I use whatever is on at the moment. The
DW drains into the disposal and the caustic soap seems to keep the drain
clear. Most bulk goes into the compost or b ones in the trash so little
has to go down the disposal. When we lived in the city, much went down, now
I get rid of trash a couple of times a week so not a big deal to get rid of
it before it can stink or attract animals.

I don't know but that is what the plumbers tell me and a search on the
Internet will tell you the same.
