Getting a snake up into the black tank inlet and the elbow leading into it via the drain valves is impossible. Think about it...

Glad to hear that it's all cleared up now.

Do you know if the clog was softened by the water or if it was something solid?
I ask because if it was something solid AND it didn't exit the black tank you may see that spider again!

It could possibly clog the dump port/valve on the black tank. Hopefully not, but it's something to think about.

Tech also stated that only RV toilet paper or 1 ply be used.

And that folks is the end of the "Toilet will not drain" saga.

Thanks again ... stay safe ... stay healthy ...

Not sure how 'unusual' that set-up is?

My last two 5th wheels have that same set up and so does my brothers SOB. (some other brand)
Seen plenty of them in basements of R/Vs at shows too. Neither of us have had any issues with this set-up but we both have followed what the tech said and that is flush with plenty of water.

My next concern... will whatever was lodged in the down pipe from the toilet, get stuck or block the black tank dump port piping or opening?

Something else to keep in mind with their setup is letting the black tank actually get full before draining it. With how inaccurate the sensors are it's hard to know when it's full and should be drained.

But back to my point, if their black tank is allowed to become full before draining then that will cause solids to settle in the horizontal pipe. This is bad for 2 reasons.

1 - Those solids can impede drainage and lead to a build-up and eventual blockage again.

2 - If that pipe is full or a large amount of water is flushed down the toilet after draining then that can lead to a "log jam" (I'm not sure if pun is intended here or not. ) in that elbow, either with toilet paper or other "solids" forming a solid mass as they rush towards the elbow and then blocks the pipe because it can't make the turn.

If I were the OP I would make sure the tank is emptied around 3/4 of a tank if possible, or at least ensure the tank doesn't actually become full before draining.

I doubt if there's a horizontal pipe. If the 1st turn is 45 and the 2nd turn is 45 to straight down into the black tank, the intervening pipe runs at a 45 angle down. This is the way it is on my 5th wheel.

Depends on the distance from the toilet to the tank, but I said horizontal more as a way to reference the pipe I was talking about. I doubt it's truly horizontal/flat as that's just not how drain pipes are installed, but the consequence of allowing the tank to fill and back up into the drain pipe is still valid. Without knowing WHAT caused their blockage all we can do is guess what it was or what caused it. Bottom line, don't let the tank fill completely and back up into the drain pipe. The pipe needs to be able to drain completely and freely into the tank.

The local RotoRooter man tells me "he knows his poop", guess that tech does too.

Many 5th wheels have toilets piped in with 45's and some length pipe going from the upper floor toilet to tank . don't see lots of straight shots when the toilet is 3 ft above tank .

Thanks for sticking with us to the end, it's always nice to hear the conclusion.

Through owning our RV we have also learned that it is best to fill the bowl all the way with solids, and try to reiterate that to guests. Even though there's a diagram on our toilet I have still found that some people don't get it.
It's hard to get guests to follow the directions perfectly. If only they were involved with clearing a pyramid, maybe they would get it lol

Again, thanks for keeping us in the loop all the way through, glad it was resolved.

Happy Camping!

That requires a lot of dietary fiber.

I wonder how HVACGuy empties the tank when it's full of solids. In my experience solids do not move very well unless you have an auger or conveyor belt.

Its a whole process, I don't want to get into now.




I didn't catch that, and it certainly didn't slip by you guys. I changed it to what I meant in my quote of myself.
