Thanks everyone for your replies. I'll try to clarify some items. This was our first time with full hook up, and, yes, we left the BT valve closed while connected. The two times we used it before, we only had electric, not water, and I was the only one using it and I made sure plenty of water was used when flushing. Also, on both previous trips, we dumped before leaving and each time flushed the BT twice after dumping - with the last flush for each trip being filling the BT until sensor reads 2/3 full, then dumping for 3rd time.

When the toilet wouldn't flush the first time, it did appear that there was "stuff" in the section of pipe just under "flapper" toilet bowl valve. That's when we stuck a piece of cut hose (no water) down the pipe to "break it up" and the pipe cleared and toilet flushed properly for 24 hrs after that, and black tank sensor never went above 1/3 full. It was the next day that it clogged again and the plunger was used. I asked SO if he had the toilet bowl valve/flapper open or closed when he plunged, and he said he can't recall - or more precisely, he can't remember sh*t But after plunging, the pipe was no longer clogged, the toilet would flush but bowl would not hold water, so toilet bowl seal is obviously broken. What's confusing me is that after the plunging, the leaking started beneath the unit at what appears to be where the dump pipe comes out of the black tank. That's what really scares me. Fixing a toilet bowl seal shouldn't be a big deal - but could we have really messed something up with the seals on the BT itself???

Hope this clarifies things. BT had never leaked beneath the unit until after the plunger incident. And, since it was only used twice before, for a total of four nights by one person (myself), and dumped and flushed after each trip, I really don't think the issue is a build up of solids.

I guess I could try adding water through BT flush and dumping again to see if anything else comes out. Could also take some pictures of the underbelly leaks if I do this.

Yes! When we were trying to clear the clog, it did appear that there was a slanted pipe from the toilet, not a straight drop into the BT.

What unit do you have ? thought is was a xlr 29 hsf . if so my toilet goes right into the black tank , no bends or slants , since FR can't seem to do the same thing twice on any of their units i would assume others also have their black tanks plumbed in slightly different on all xlr29's. there is a large space below the ball and before it hits anything below the floor someone would have to be really relieving a lot of BBQ to clog it up .rotfl

on your leak i would empty tank then fill with only water and mark where it is leaking . then you can see what needs to be done then come here with the full picture and i'm sure someone could help

Using a medical glove and some silicon grease, you can usually reshape the seal door gasketback to round. I've done it, no disassembly. This assumes there's no tear.

My 29HFS drops straight as an arrow into the black tank; my toilet is mounted directly over the black tank; no need for a drop pipe, unless it is only a couple of inches long.

I can't imagine what an angle pipe would be for, unless the factory left something there that they should not have.

If you open your flush valve and look down there, do you not see the bottom of the black tank maybe 8" to 10" below? Use a light if necessary.

I have read on this forum about member having a back-up problem and there was a drop pipe from the toilet flange into the black tank that wasn't cut off, rather it was sitting on the bottom of the tank; preventing solids from entering the tank, while only liquids could run in. Again, my unit, the same model as your's, doesn't have a drop pipe that I can see.

Thanks for chiming in WW .. i though they were all the same . not room below the toilet and tank for a 3" slanted or bend anywhere . if something was left in the tank or hole not cut for toilet there would be issues but it never would have worked . i'm back to major build up in tank . you can't dump these things everyday unless you adds lots of water first

I add at least 5 gals water to an empty black tank... Then bio stuff to break it all down. No bleach or strong anything. Never had a smell in trailer. I let it fill to full at least over 2/3 full then dump. Flush at least twice till clear... Close the valve and start over with 5 gals... Etc

You are right dumping and not rinsing / flushing everyday not advisable

Let it fill and stand with a good natural bacterial... It will break down... Might take a few days or more. Some folks use Rid-X

Well, we finally had a chance to take a close look at our issue today. Interesting find. There was a small pile of TP just below the toilet hole, but not a mountain blocking it. After seeing what the BT flush didn't get, I'm thinking forget that, just drop the back ramp, bring a hose in, and flush the tank from the toilet itself - which is what we did this evening.

Here is the real issue/culprit. The hole Forest River cut in the BT doesn't fully line up with the straight down drop pipe of the toilet (I was wrong about thinking it was slanted). There is a crescent moon shaped section of the BT hole that obstructs a part of the bottom of the toilet pipe hole. I'm guessing that when something other than a "pee" is flushed, particularly if enough water is not used in the flush, sh*t gets hung up on that crescent moon causing a clog (pun intended).

And this misaligned hole issue is the cause of our leak in the underbelly. When I only filled the BT to just below the crescent shaped misalignment of holes (doing so with a hose in the toilet with a flashlight), no leaks from the underbelly. As soon as I tried to fill up the BT so that the water rose up into the toilet drop pipe - no dice, couldn't get it to fill beyond a certain point and it began leaking from the underbelly.

So, obviously, once water gets above the misaligned holes, it begins running on top of the outside of the BT, and leaks through the coroplast underbelly where pipes come out around the gray spray foam insulation. Query - shouldn't there be some type of seal or sealant where the toilet pipe dumps into the BT????

Also, and this scares me a bit, when crawling around looking at the underbelly, I noticed that our coroplast underbelly has bowed down under the BT and is actually touching the TH's axle - presumably from the weight of the water that went on top of and outside the BT instead of inside it.

I'll be calling Couch's tomorrow about this. Since we're about 2 hours away from a reputable "bricks and mortar" FR rep (refuse to use Camping World that's about an hour away as they have a horrible service reputation), I have our mobile RV repairman that we've established a relationship with coming for a service call the week after next. I haven't filled him in yet on our discovery tonight, but will do so first thing tomorrow. Anyone have any thoughts on how tough a fix this is going to be? Think it can be something that can be fixed "on site" rather than in a shop? Wondering if the BT will need to be dropped. Any thoughts/advice are much appreciated!

From your discretion I would thing it is a major fix that may call for factory to do. either the BT needs of be moved to align with the toilet or some other fix to ensure there is a seal and that no obstruction stop your poo from hitting the tank. this is more the mobile RV in my limited judgement. I agree with you about Camping World RV service.

Easy fix . just shut water off disconnect toilet supply , then 2 bolts at base of toilet ,pull toilet and cut out the half moon shaped piece of BT they missed . my guess is the hole is misaligned. if that's the case then it may not be sealed corectly and forget what i said above get a new BT
