No Dump Porta Pottie

[clyle]

Got tired of carrying my PP to the bath house to dump. Decided to plumb a maserator to a Theford model 260P (marine toilet). The present design fits under the front bench seat and pulls out to use. That necessitated using a flex hose and some innovative pluming, but it works. A macerator can empty a 2.6 gal PP in a 5 second hurry. I have pics, but they won't upload for some reason.

Wow. Pretty crafty I must say! I agree the drive to the dump station ain't no fun! However, I don't use mine for poop, so no need for the macerator on this end. You've got camping season coming up so plenty of time to test it out. Happy testing!😀

Already tested (using water). I'm in Florida and it's being used.

And, where does the poop go if you don't have to make trips to the bath house?

The macerator pumps it out of the PP holding tank and then out of the trailer through a garden hose into the RV park's sewer system. I don't know after that.

So, there is no black tank and you need full hook-ups to make this work? It's not really "no dump" and restricts you to "RV parks".

Great idea Lyle for those of us who often stay in serviced sites but don't have a trailer toilet.

I think it is pretty ingenious, and I don't think it would restrict you to only RV parks, lots of state and national parks here have dump stations so you can dump when leaving, unless of course it fills up before your departure. The no dump would depend on if you have the full hook up or not vs. using a dump station. Camco has a handy sewer cap plug with a garden hose adapter that would probably work well for you setup clyle, I use it with our shower for grey water when we do have full hookups, other wise we use a portable gray water tank.

Lyle,

How does the "product" get into the pumping system? Do you have to tip the porta-potti on its side so it drains into the pump hose attached at the bottom tank?

How do you rinse the porta-potti tank after emptying it?

Another potential issue:
I've read on the forum, but not experienced that some parks require the use of a 'donut', a device that seals the septic dump pipe to the slinky hose.
That obviously wouldn't work with a garden hose.
Don't know if those parks have 'donut police'.

The "black tank" is the 2.6 gal holding tank on the Theford. A bit small, I'd admit, but it's a small trailer eh? It's got a small fresh water tank as well. Sure I need full hookup for the maserator system, RV parks are where I spend most of my time. The 2.6 gal holding tank is good for 4-5 days if I'm watchful and then I do need to pump it out in some manner. So I'm not restricted at all. I also still carry my older "dump" model Theford on those trips where I'll be spending extended time in parks w/o sewer hookups. The idea for doing this to begin with was to reduce or eliminate having to carry a couple of gal of liquid sh#* to a public toilet.

No Problem.

Not my idea of fun either, but I have a 20 gal. black tank.
Never have understood the reluctance to use a sani-dump to empty the black tank.
I had a porta-potti years ago at my cabin and was thrilled to leave it behind when I sold the property.
I presume you don't leave the hose in the sani-dump when not dumping ( which is why some parks would require the 'donut' ).

If a sani-dump is those wheeled plastic tanks then I personally consider them just a larger tank of sh#* to haul around.

The maserator is permanently "plumbed" to the Theford marine toilet which is designed to be pumped out. The maserator pumps the stuff out of the holding tank on the Theford, grinds it up such that it will pass through a 5/8-3/4 inch garden hose and then pumps it through the hose to the sewer system. What I did really is just a scaled-down version of what is on most larger RVs. Most of them have a maserator in addition to the flex sewer pipe setups. Cleaning is easy. Just dump a gal or two of clean water into the toilet and let it run through. Add a little chlorine if you wish.

Yes sir. That's the same setup I had going into this project. Just added a "Y" connector at the donut to add the pump out hose.

[Glenn Baglo]

Nope. Sani-dump is that pipe that the effluent goes into, via a 'stinky slinky'.
No hauling, no mess.

Oh! Well, I've got a 15 foot, 1978 model Trillium and do the best I can with what I got. When I get my $250,00 motor home, I won't be doing these things. Meanwhile.........

Sounds like a good idea for those that just have a porta potti and not the black holding tank. You still have the flexibility to dump in the campground toilet, or use the macerator when camping longer term where you have full hookups.
