Yep, I said "macerator" from the toilet but what I really meant was just the pump/motor assembly that functions as part of the toilet itself. Ours has a thing called a "chopper" in there, so I assume it functions much like a separate macerator would, at least briefly.
That "chopper" doesn't function much like
a macerator, it IS
the macerator. Doesn't matter whether it's in a macerating electric toilet or a macerating overboard discharge pump, a macerator is just the "chopper"--essentially the same thing as the blade in a blender--nothing more.
So macerating toilets don't have a macerator between
the toilet and the holding tank...the macerator blade--aka "chopper"--is a part IN the toilet pump.
What everyone calls a "macerator" (referring to an overboard discharge pump) is actually a "macerator pump
"--a pump with a macerator blade in it. But everyone thinks that "macerator" is what the whole overboard discharge pump is called. So it's not surprising that you don't know what a macerator really is...I doubt if very many others here do either.
