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..
