Home made waste pump
Has anyone made a sewer waste pump from a house sink disposal from under the sink? I saw this someplace once and cant find it. Thank you in advance.

RV Macerator Pump
The gray flow thru. Pump the black as needed. 75 feet thru a 3/4 inch hose. Works like a charm. No worry of overheating the 12 volt pumps.
I know this is in the class A forum, but it's applicable to any RV with holding tanks. It's a good idea.
I can't figure out where the pumping power comes from, to have any lift. Is it just the centrifugal force generated by the garbage disposal?
I don't know how far it will pump the Black stuff, but before I used it, I connected my 75' 3/4" garden hose and pumped out several gallons of clean water from my gray tank. Holding the hose about waste high, I was surprised that it shot the water up at least 10' into the air.
I also have a 12 volt macerator pump and it will not pump as high.
