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.

Not true, I have a garbage disposal that I use to grind up my black waste and it pushed the waste thru a 1 inch hose 45 feet away into my cleanout at home, works every time..
Post the brand and model of the HOUSE GARBAGE DISPOSAL. I have replaced at least 4 in my lifetime and NONE have a pump in them. Besides, WHY use a House Disposal?????? What is the matter with the standard 12 VOLT RV Macerator?????
If you go to the previously posted link, you'll find that the fellow used an old Insinkerator disposal he already had, plus some added hardware so he could pump to his septic tank at home. It didn't cost him anywhere near what a commercial 12-volt RV macerator pump costs. Even buying a similar new disposal would be cheaper than a commercial pump setup. It's really a pretty simple conversion...
DIY RV Macerator Pump
As I stated, it does NOT PUMP. It is gravity fed and if you look at the link design, the Black and Gray tank are ABOVE the Insinkerator and when he fires it up it grinds and GRAVITY and the force of the black/Gray water from the upper tanks push the debris out the Insinkerator thru the drain hose. So, what I stated is correct. Home disposals only grind and they are 120 volt. RV 12 volt macerators GRIND and PUMP the debris. A PORTABLE 12 volt RV macerator is $195 on Amazon with fittings to match RV's. CHEAP Garbage disposals are $65 up to the better ones at $130, THEN you have to modify and make it fit and then supply 120 volts to the Contraption. While you could save very few dollars, the plain fact is, it is just a crazy thing to do. Doug
PS, that link, the guy has a septic tank and he just drains to his tank. Unless you have a septic tank, what good is this contraption? Very few homes have a easy sewer input. And you cannot legally drain sewer to land even in the country in most areas of the USA. I know in Texas, that is true. I had a Co-worker that lived 30 miles out in the country and got fined for discharging Washing machine water to the backyard of his home. A neighbor turned him in.
