What's the max angle for... uhh... toilet tube. ;)

[Chaz]

I have been wrestling with this mess all day. Here's what i think will work for me:
 
  Kids slide down the slide on a 45* angle about 12" long. (I just can't get away from that  )
  Sinks drain right into the waste tank. (I guess a little extra water in there is ok from what I read) It is a 100 gallon tank.
  Shower also drains into the waste tank, BUT, I put that extra shut off valve in the line to be able to drop the shower water on the ground or where ever.

All lines have fernco's in them for access.

I wanted to drop the sink water thru the "slide" but just don't have the room.

  Tomorrow we "glue"!  (unless of course somebody has any more suggestions )

You'll be fine ... do it your way. I don't run any extra water down the poo hole, I have a sealand ceramic RV toilet. ... and I never have any of that ... poopy morning build-up

Sounds good. I have a 12 inch drop with two 45* in it, no problem, and that is fulltiming for 6 years!!! Is there a way you can put in a bypass for all the greywater?
ie if you run the gray to the tank install a tee with a slide valve on the bottom, with the valve open it drops into the tank, closed it keeps going. If doing this it is a good idea to put a zerk grease fitting in the slide valve. they do not like being flat.

Not really. I mean it's possible, but I'm trying to keep the spaghetti to a minimum.  It's a pretty clean minimalistic setup this way. And I don't think the water from the sinks are going to be all that much. As it stands the tanks are, 100 gal. clean, 100 gal. waste. I REALLY wanted to put in a grey tank and a black tank, but it just wasn't in the cards. I still really like that idea but I think this is a happy medium.

  Thanx guys,
       Chaz

  ok, I couldn't stand it. I started gluing tonite!

Chaz,

Stuff rolls down hill.

A 45 degree angle prevents an unwanted splash.

A little water in the bowl helps the Stuff go down.

These are the facts as I know them!

[Chaz]

Ya know what Cliff.......... Come to think of it, I don't even know how to use an RV pot!!!!!!!   
Seriously!!!!!!!!!!!!! Is there a trick??

  UH-OH,
     Chaz

Since I have one 90gal waste tank I want all the liquid in it I can get, makes the solid stuff break up and dump much better.

[FloridaCliff]

Lift up on the flusher with your foot and it puts a little water in the bowl.

Down sends it to the abyss.

A little practice and its easier than shifting a spicer....LOL

Chaz,
     What are you doing for a tank vent??  Absolutely must have one!!  Best is 2" through the roof, usually hidden in the shower wall.

Cliff,
  I have some sort of lever or valve kinda behind the left side of the seat. It's a Thetford, but other than that........? I'm assuming I can push it in two directions, but not sure. I'll check when I get out there this morning.

  Jerry,
  Unfortunately, I don't have any walls to take it up thru. Maybe a closet tho. But I was wanting to try something that I had read sometime ago, and run it thru the floor. Actually, 2 of them. one on either side. Once the pipe goes thru the floor, I am going to put a 45* elbow on it. One will face forward and the other backward.
  If it's true that air (oxygen) keeps things from smelling - and I believe it is - this should give it all it wants. If not.............  ............ I'll weld the plates back in and get creative thru the roof.

   Trying not to be stinky,
            Chaz

If you go travel the entire world you will not see a vent pipe through a floor.Ask yourself why?  Except in a couple of bus conversions.  In the process of decomposition things get warm, heat rises!  Now if the vapors do come out, and there is no wind do you really want the smell sitting under your bus? Even if you used a power vent, you will still be sitting in the odor.
One elbow pointed forward? Seems like a recipe for disaster!!! I have a vison of the pressure blowing the water out of a trap and forcing the odor into the bus.
This is only my opinion of course, I may be wrong.

[FloridaCliff]

Chaz,

I ran a 2" pipe like Jerry described.

Works good, I also built a little venturi type cap on it with a tee and a reducer on the forward facing part of the tee.

My concern with the thru the floor is the same as jjr's.

But, If you have the time and want to experiment I would look forward to your results.

Sometimes the road least traveled is the most interesting.

I think the forward facing vent would cause a nose full if anyone flushed while driving.

Remember there is NO trap in a RV toilet.

[Chaz]

Pretty strong opinion there.  But you may have a point. I AM  the "new guy".

  But to further explain:
  The vent tube with the elbow forward is 1.5". The tube with the elbow backward is 2". I think that should help in the pressurization dept. And the 2'' will be on the drivers side away from the side we would be hanging out on most.
  Plus, I was figuring that with enough air getting to it, the smell would be lessened a great deal. At least that is how I read some of the posts in this thread.
   Hey, maybe it won't work! I seems good on paper. Has anyone else tried this?? It would certainly make life easier on me if it did work this way.
   I'm always open to people's thoughts and ideas. (and areas of expertise!  )

   Just ventin,
        Chaz

    Just seen you wrote Cliff. Good point about the flushing while driving. Hmmmmmmm.........

my 2 cents, while were CHITtalkin

Mine came strait down with a ceramic Sealand(i think  dont get close enough to read label) and has big ball valve like navy toilets.

strait down is just simpler, if something happens, it simpler to address.  more complicated things will work i'm sure but IF/when something were to happen, clog etc., it's less simpler to address.    somewhere down the road you may find you wish you would have moved the vanity while your in a precarious position.

For us Bigachitta types, the bowl is too small for the final relief of "Travel Constipation".  I push the pedal down on the toilet for the strait shot so it won't lift me off the seat and it's a nice courtesy flush for the small space close to the kitchen.  

I also added the kithen sink sprayer when i replumbed it, saw it at the RV show figured why not,  not sure what its for, but I reckon a redneck biday is what it is used for sometimes.  and to pressure wash skid marks

Make sure you have room for your elbows when you reach your nethers. sit and try before you cut.  make sure the plumbing is accessable and try to protect from freeze.  use pex push-on fittings, expensive per fitting but cheap per job,  reusable and easy.  pex less freeze resistant.

I'll have to try the push-up thing, thanks cliff.
