Macerator pump systems

Had one on my Roadtrek...when I sold it, I was so relieved to not have a macerator on my new rig! I really didn't like it as you never knew, for sure, when it was through pumping...and I figured it was just a matter of time till the motor burnt out.

I bought a portable macerator pump at West Marine. As expensive as boat items are, they actually where lower cost than a RV supply store for a macerator pump.....text deleted...

I use the same type marine macerator pump with a few pvc fittings to allow my normal sewer hose to connect to the macerator pump. My home dump station has 1 inch pvc running about 75 feet, and this works well. I use a short flexible hose to connect the macerator pump to the 1 inch pvc, and get power using spring clip connectors to the power at the leveling pump.

I have a portable.. And a 50' Black Hose to go with it (The hose is black)

I have used it on occasion to pump to a sewer inlet that was far, far, from RIG.

Work great.

Normally though I use the 3"

Works FASTER

Does anyone use or have used a macerator pump system on your RV sewage outlet? I am considering going that route.

You don't say why you want one - or why you think you need/want one?.:R

*If* you need to pump sewage a long distance - or uphill, or both (for whatever reason) - it's nice to have..:C

I have heard that macerator pumps can burn out if you run them dry. If this is the case, how do you empty the liquid in a long hose once the liquid has stopped entering the pump?

The Flojet has a connection for attaching a garden hose so that clean water can be pumped thru unit after dumping to flush the macerator and discharge hose.

I use the regular hose to dump at camp but when I head home from a trip someone always needs to use the bathroom (me included) when I get home I hook up the pump, get a lot of water into the black tank to suspend any solids and start the pump into a line I had installed for the camper. good clean tank and empty too. Don't have to wait for next trip out or for that matter, and last week was the last time this year, winter is a coming

We have used our OE macerator for 8 years with no trouble. At a dump station we pull in, dump, and leave in the time it takes a gravity rig just to get set up.

I used one for 7 months last winter, we were living in ours while the house was being built. I used 1" PVC and was 220' long. Worked very well. I used a separate 12 volt, 30 amp power supply. The only glitch we had, was when the wife bought cheap Wal-Mart brand toilet paper. We use Scott's brand religiously now.

Have a FloJet, We camp at a place with water and electric and a sewer dump 150' away and maybe a couple inches higher than the trailer. So the first year we had 150' of 1" flat hose on reels. Ran the hose out, hooked up the pump and after a while burned up the pump. Spent the next couple hours replacing the brushes, cleaning the armiture and getting the pump running again. Put it away for a couple years.

This year I had the bright idea of using 1 1/2" swimong pool back flush hose. This time I'm another 25' away from the dump station so I need 175' of hose. Well, 50' of 1" first, then the 1 1/2". Well, the pump couldn't build enough pressure to unkink the pool hose so it was pump for a minute, then take out the kinks. Run again, new kinks. Finally after about 2 hours I have both tanks dumped, then comes the cleanup. Needless to say the tote tank may be a bit more physical labor but time wise much shorter time than the pump.

A marine grade pump I'm sure would work fine for most distance.
