My class B came with the regular stuff, a flexible hose to drain the black and grey tanks. I wanted to be able to drain my tanks at home and not go find dump station after getting home. I love it for several reasons. This it what I like:
1. I no longer have to worry about having to store the flexible hose in a container box as I travel. The pump is in a small box that doesn't take up much room. It also seals well so there is no odor. The flexible hose storage that came with my rig would not store a hose long enough for to reach some of the places I had to drain to.

2. I can wait a day once getting home to drain the black and grey tanks.
3. I pump straight to a toilet in my house and dump easily.
4. On the road, I carry a 15' foot hose in a pvc pipe hung under my rig. At a dump station, I attach a clear 90 degree el to the standard outlet, then attach the macerator pump (this allows me to visually set the tanks are being drained and allows the pump to slope downward for complete drainage), and then I attach the 15' hose and pump out the tanks.

5. The advantage of the hose over the large flexible drain hose is it drains much better. It has no ridges for stuff to get hung in. Also the macerator chews up everything to a slurry and it flows out the 15' hose so nicely.

I did have to run power to a point that I could plug the pump into the power. But, for me that was no problem.

Doug,

Sounds good! Can you tell me what macerator pump you are using please. I had thought only to use the macerator at home, if I had just been using the van for local day trips with no easy access to a dump station.

But I guess if you buy the pump, no reason not to take it along on camping trips and use it anytime if it doesn't take up much space. You would always have gravity backup option on the road if you have a problem with the pump!

If I understand, this is what you are doing?

Thx ......... Brian

I use a FloJet. Yes I take it along on trips. If the pump wouldn't work for some reason, using only my small hose would not be practical. But, I have used the pump for 8 years with no problem. Once it got jammed with a cleaner wipe but the pump has 3 screws to take lose to fix that problem. You could buy an adapter to go from the RV drain to a hose connector and that would allow liquid to gravity drain but any solids would probably hang up in the adapter - a cleaning mess but better than not getting to use the toilet at all! The 15' water type hose I carry in the pvc pipe under my rig is the thing that saves the space and keeps the smelly stuff outside.

For dumping at home, we modified an $80 garbage disposal to dump 70' uphill to our septic clean out. Since it runs on 120V it is powerful enough.

It must be toted out to the van along with a power cord, as well as the output garden hose all will need. We flush the slinky connection with the sprayer on the back of our Travato. You can find out how to build these on you tube.

We are glad to have the option to dump at home.

Interesting solution. Can you post a photo of this device made from a garbage disposal.

Hi Boxster. Here is a photo of ours and some links that inspired us to make our own "poo shooter".

Well that is something for me to think about! Cheaper that buying a flo jet and no need to worry about 16amps of 12vdc as I would only be using it at home and 110v ac obviously available.

One thing I wonder about and maybe you can comment ....... I would only be able to dump into a toilet in our powder room adjacent to the garage, so I guess it would be a two person operation with GMRS radios!

But even with two people to keep things under control I am wondering if the flow might be so forceful as to make a real mess all over the powder room?! (Maybe I'll ask my wife to look after that end of the operation! - Just kiddin')

I suppose you could put a ball valve on the hose end to control things better - and maybe even a control switch on a long extension so that in fact it could be a one person operation.

Should work fine for us s we only pee in the toilet so shouldn't be much opportunity for problems with the garbage disposal unit.

Presume that once empty you would fill the black tank with water and flush everything through to clean the hoses and pump?

Brian.

The output end on our 70' garden hose does not go out of control when the disposal is on. I expect there would be no problem in your bathroom either, but monitor it the first time to be sure. We aren't getting the high pressure output some of the web links refer to. Our system is slower to empty than by gravity to a station, but fast enough.

We don't often flush our blank tank after dumping, but you could if you want. We do rinse the slinky right into the disposal. I must admit we also only wee in the RV, but I'm sure the disposal system could handle poop.
