Macerator pump.
Yahoo Message Number: 153262
Ok it's time for us to take the plunge and get a macerator. Question is which one? Or do I steam punk together one from an insinkerator?

Let me have it people. I got galoshes on!!! Lydia

I got mine here: Thetford Sani-Con System - Macerating Dump System - PPL Motor Homes

It works well but the supplied outlet hose is flimsy. Larry modified mine by using a short hose and clamps from Lowes. Now it works fine, although I don't use it often.
The tank buddy model comes with toolbox case which is handy. Usually use in remote places like Death Valley.

Lydia,

I have one of these Flojets:
 http://www.amazon.com/Flojet-18555000A-Waste-Water-Pump/dp/B001HKZHIW/ref=sr_1_1

It uses the standard garden hose that you have to buy separately.  I bought a couple distinctive black 15 foot hoses at Home Depot.
 Not that I have used a huge number of times, the unit has served me well.

Real RVers build their own macerators.

The Floret shown previously looks like a a good choice. It will work in a variety of conditions and is not limited the way the Sewer Solution is. With a 3/4" hose, it will pump a long way.
I carry a big pipe wrench an a 4' breaker bar for opening sewer cleanup caps, great for opening sewer cleanout caps. A minimum of 50' of hoses should carried(5/8" hose is OK).

Sounds like you may have been inspired by this site?  :)

DIY RV Macerator Pump

I put together something very similar to it.  I bought the cheapest disposal ($50), a clear elbow to attach to the RV ($6), and a 1.5" pool discharge hose ($15).  Everything else I had on hand.

Works great at pumping everything around 25 feet up a 3 foot incline.  Don't know if this link will work, but here's a picture I took of it.

Let me know if you have any questions! Russ

Yeah that was the one. I would have to gussy it up to fit into CaptNemos ship but hey that's fun too.
 I was concerned about the length of these units. Do they hit the ground when installed to the dump exhaust?  I have an 06 31 ft and the single exhaust for both tanks.
 I notice most have some short slinky hose attached but the flojet doesn't.
Ill have tocheck clearance

My 2001 LD has a dump valve which points straight down on the black water tank. I have no problem with bottoming out the macerator. I have the Thetford unit. Since my chassis is an E350 it sits slightly lower than yours. You shouldn't have a problem. You will need long jumper cables to power it if your batteries are on the opposite side of the rig as mine are. Better to have some wiring from the 12V fuse panel to a socket near the dump valve installed.

Cool way of using an old garbage disposer. Never gave one much thought as a macerator.
They are tough, lasting years in home use.

The downsides include it's big size and very heavy weight (not the hot ticket for a 31" model) and that 120-VAC electrical is needed to operate it.
It could make a good home only unit.

The biggest difference I see is the ability to pump uphill. Disposers are designed to pump into a gravity drain, meaning they are not meant for pumping to a drain higher than the outlet of the holding tank or pump.
Our Jabsco macerator pump will lift to at least 10'.

It would interesting to see a pump performance chart for a garage disposer, compared to a marine macerator pump.

FYI

The Jacsco macerator will pump 7.5 GPM, at 20' of lift.
Shurflo does not publish its macerator pump's lift performance but it should be similar.

My top-of-the-line, brand new In-Sink-erator is a disgrace to garbage disposers everywhere.  It rejects everything except mushy things - even a well-aged banana skin gummed it up.     :-(   I cannot imagine expecting it to deal with toilet paper.

Yep, I was surprised to read about the success the guy on the "steampunk" website had.  He said he was able to pump up around 7 feet with plenty of flow using a garden hose outlet.  I'm able to pump up about a 3 foot incline through a 1.5" hose, with plenty of flow.  The tanks empty in a couple of minutes each, tops.

Yes, the downside is that it's heavy/bulky, and requires 110v.  Not a big deal for me, as it is my solution for dumping at home, but YMMV.

My follow up.

1 valterra 45 degree one piece clear angle.
1 50' 3/4" hose 15' of 10 gage stranded wire in red and black with butt connectors and 2 large yellow crimp on eyelets

Some brass and PVC fittings to get the exit into a drain clean out

And 1 flojet macerator.
 we had a 90 degree clear camco piece that broke on the first handle pull. That was not fun. I suffered through some jury rigging until I knew I wanted to continue and found the solution.
 Smal length of wire on batteries that stays in battery compartment and a fixed extension on the pump to handle the job from the valves. That meant a fixed no spill solution at the far end which Home Depot was happy to sell me. So now the whole thing is stored under the coach and I just connect the bits when needed.
 Once we are back using her recreationally I can still use it but with a tad more set tup fuss.
 Perhaps when it cools off and I have less honey do list, I'll run the electricity across the coach internally.

Thanks for your help! Lydia.

Renovating a desert home, in the summertime, must be a lot of laughs.

Stay cool (as much as you can).
