If it can do that to an Apple, the average turd has not a chance unless maybe if you had way to much swiss cheese, then all bets are off.

Bought a used garbage disposal at the local "Habitat" store for $10 added about $20-30 dollars of parts have used it for years. Will pump 100 feet with about 3 ft rise (that's the most I've used).

Works perfectly.

Thanks. That makes five now.

I think at this point, it is incumbent on the naysayers to prove their claim that a garbage disposal cannot be used to pump sewage uphill. I’ve never used one like that, but I’ve replaced several, and played with a few enough to know that the water doesn’t just “fall” out of the disposer thanks to gravity. It’s under pressure.

Otherwise, I trust that said naysayers humility will at least allow an admission that their claims should be afforded the same credentials as they afford other interweb based claims; they don’t mean squat. Possibly even less than that.

Diddly squat.

Diddly squat, and whoopdeedoo.

Perhaps you can explain why by IPC, when your drain exits a wall the invert needs to be below the weir elevation of the trap exiting a disposer? Typical forum nonsense, and you have more BS than a cow pasture.

Done with this mental masturbation, happy new year

the people that say it won't work have never seen one in action. i and others at my seasonal site have been using home made garbage disposal macerators for 5 years and they work very well.
i have 75' of 3/4" garden hose to the dump station and i dump weakly during the 7 months of the year i live there.
there are utube videos of people using and making them and one guy on utube is making and selling kits on ebay to convert garbage disposals if they did not work why would he waste his time making kits to sell? and would not every one he has sold to send negative feedback about them.
my homemade one works great and makes it a quick job dumping my tanks.

Do what you will. Even knowing a disposer would work perfectly OK I would still get the macerator designed for the purpose.
I am not naysaying anything, just not my style.

I appreciate all the input. After reading all the posts it, as usual, comes down to who is speaking from logic and experience and who is just speaking. I may try making one on-the-cheap with a used disposer and see if it works. I'm in no rush and if it doesn't work well I won't have too much invested.

I guess I'm just a born tinkerer and this kind of non-traditional project that is up my alley. If for some reason I don't like it I'll go with an over-the-counter, traditional model. As said, I don't want to have to wire the 12 vdc from the opposite side of the coach when I have a 120 vac GFCI outlet next to the wet bay.

No problem. I enjoy fabricating things myself, and I respect the skills of others who do.

I actually used to have a 12v Flowjet macerator, and it worked fine for 3-4 years. It eventually quit though, and I thought the price was too high to consider replacing it. You do have to keep them clean, and since your going to be pumping shower water through them, they will get hair in them that will have to be cleaned out. They have to be taken apart to clean them.

I will warn you though, if you end up using the 12v macerator, you need to get the full cooperation of any females in your group. Their products will kill a poop grinder pretty quick. I doubt a garbage disposer would like them either.

Tinker on, buddy. Show us what you build!

Unfortunately, I don't have much hair left to shed. My wife sheds very little and only washes her hair every few days. Hair is not the problem it once was. I'll address that issue as I come to it.

She has already learned that lesson, living on a septic tank system. Everything that says "Septic Tank Safe" is probably lying.
