DIY RV Macerator Pump

Going to make a Macerator pump this weekend from a garbage disposal, I have seen plans on the internet and feel this will be better than the weak 12 volt one I got at Camping World for $240.00 that only after 6 months of use it has stopped working, would take it back but cant find receipt for warranty plus I have already dissembled it to see why it stopped working, the motor has gone out, its to weak as far as I concerned, so a 110 volt should work better.

And yes I do use a 3/4 hose but my distance is about 45 foot so I think the 12 volt just wont perform long term..

Any ideas on what works best would be great to hear before I head off to Lowes..

    Tim, looking forward to pics and feedback on how it works!!!!

    I have considered a macerator pump, but the time I would need one it could portentially be about 125' or so to the drain.... Not sure if one would work that far???

    I had considered the diy that Tim just made. Wondered if hooking water up to the dishwasher drain fitting would help "push" the slop through the hose.... I would add a check valve if I went that route.

    Any suggestions???

    Thanks,Mike


    Yes I might post some pics soon, it runs off my 110 plug in the drain compartment area, I only use it at home and use the 3 inch drain hose at camp sites.

    I have finish my new DIY RV Macerator Pump, I used a 1/3 horse power garbage disposal that I picked up from Lowes and some misc fittings, a new cheap sewer drain hose plus fittings, and put it all together today and it works like a champ, { about $150 total } seems like it has no problem doing the work unlike the 12 volt that struggled from day one, I will soon build a box for it so it stays out of the rain, its only used at my house to drain tanks into house sewer 45 foot away, when I pull out it stays home..

    That looks familiar :H
    You are right, I didn't follow the link you posted earlier in the thread. I didn't know it was the Steampunk website. Sorry about that.

    Use it to pump 75' with a 2' rise.

    Works great and I always have 12VDC


    I have a newer Flojet that failed. There appears to be something wrong with the material construction of the brushes on the unit I have.

    I think the brushes have a higher resistance then should be; makes them get hot and the brush holder melts and fuses to the brushes. I guess I should have taken photos.

    I actually got a set of older brushes, and replaced the first failed brush. Well, of course, the brush I did not replace failed even worse then the original and made the brush holder a molten mess and as such the motor was then essentially trash.

    Newer items purchased seem to be of lesser and lesser quality these days.Buyer beware of new purchases.

    I believe that's the one.
