ok he messed up my tank install.
Ok the last few frames are my fingers, looks weird.
So the toilet is ACE perfect.
We went to put the tank up and blammo, the install guy gave up and quit.
turns out he was just a pretend worker plumber.
The connector I can use flexible PVC, but its now a very weird drop. almost sideways? can it go sideways?
Should I just pay $300 for a custom tank with the drop near or almost near the inlet?
Yes there is now a muffler tube close to the tank, but the tank will go up near 10 inches.
Its just a mess!

So, that tank is your black tank? Can't quite see in the video, but any chance of sliding tank back?
Shoot, I'd just leave it like it is and tell people to only use it on the highway.

What about capping the incorrect hole and adding a new one? Uniseal should do the trick.

yeah I spent $2000 on the floor. its stunning.
now with a hole.
so I wonder if it goes down 3 inches then a right angle turn? then down the side and right angle into the tank>?
yes black water.
And now a 3 inch hole in my bus.
Solution is to math out how long a toilet line can go and not be straight down, you know right angles and 90 turns.
Solution 2 is put a furniture item there.

I was talking about reposition the hole in the tank to match the hole in the floor.
But move the toilet over the tank and put the sink over the hole? Or a cabinet...

good idea. I wonder if it will flow with right angles? I had planned on a drop but messed it up good.

re-using an old tank is a pain in the ass.
imo - poo should not have to move sideways more than a few inches to your drain. idk that you need a custom tank, but one with out hole will make it easier to put yours where you want it.
with my bus, finding a place to hang the tank was the challenge. i made the bathroom straight above it.
to use what you have, you can probably glue a piece of abs over the tank hole and start over. cut out a 4" hole for a 3" uniseal and your waste pipe and you should have you patch for the other hole.
good luck

oh... and everyone that you hire will be the same for working on a bus. pro's don't work on rv's - 9 times out of 10
you got to find someone that that can read your mind, fix your mistakes, and not charge a fortune.

Yes it will flow with a horizontal turn use the longest turn elbows you can fit in there but don't use the short/close radius elbows for pressurized water lines.
FERNCO is a brand name but they also make rubber elbows with hose clamps on the coupling ends that might be easier to use there with a piece of pipe on the horizontal.
Make sure you have a minimum of 1/8" per foot of slope/grade to the tank after the bus is loaded
You will have to ensure you park as close to level as you are when you plumb in the tank to ensure that slope
If you do go the FERNCO fitting route then you will need to support the fitting attached to the toilet end to make sure it doesn't pop loose on a bump or a big dump of toilet water.
Good luck

If going pure freshwater, can I rig some 1/2 inch plumbing to the toilet with a valve and a "T" over to the sink/shower?
I have a 55 gallon barrel that will get installed, soon...
For now it is going to a septic and not driven.

Opinions may differ somewhat....
Using a regular 90 or sweep will likely play reasonably well with a 1.6 gpf toilet but with RV toilets that accompany solid waste with a fraction of the water to "wash it down" you may find that any significant change in direction may cause issues.
IMHO: there IS good reason why you see RV toilets & black tanks arranged so that there is a straight drop from toilet to tank.
Just my $0.02

As Steve says, any time you ask an RV toilet to move "solids" sideways to the poo tank it will take more water, a lot more water, to prevent blockages. You really want a direct drop straight into the tank, even if only to help clean the inside of the tank with a flushing wand down the loo when needed. I use Uniseals for my fresh water tanks' gravity fill inlets in their top surfaces, and they seem to work well. Just remember to lubricate them so when you slide the pipe down inside them it won't dislodge them from the tank and push them down inside the tank itself - don't ask me how I know about that. And I'll let your imagination fill in the gaps about what lubricant works best . . .
The mark of a true busnut is how much time and effort he expends on matters excretionary. I'm always amused how often such subjects are discussed on the BCM forum. Thomas Crapper, of all the great Victorian inventors, you're my hero.

Don't know how much room you have between the tank and floor, but two 45* elbows would work better than 90*s....your horizontal "sideways" pipe would be on an angle rather than straight across...another $.02 worth.
Straight up is the best.
