Something doesn't seem right on mine. If I look in the toilet, it appears that the down pipe goes too deep in the tank. So I measured it and the pipe ends 3" from the bottom of the tank. I would guess that the tank is 6 to 10 inches deep (just a guess). So it seems to me that the pipe should end at the top of the tank. Is this tank maybe only 3" deep? Or is this thing plumbed poorly.
We are finding the 3" gap to cause plugs occasionally and that is no good at all.

This is a common problem due to poor construction. Go up on the roof and remove the cap to see if the pipe dropped. If it is at the right position, it may be too long. You will need to move the pipe up till it is near the tank top, I suggest that you determine the type of seal used there, and position it as required. Now the pipe may need to be cut to the length, supported somehow, and the roof exit sealed and capped.

Thanks Lynnmor. I may well have issues with the roof vent as well, but at the moment I am looking at the pipe from the toilet into the tank.
How are these constructed? Can I remove the toilet, then remove the floor flange and just pull it and the pipe into the tank up and out of the tank? If so, then I could see how tall the tank is and cut the pipe appropriately. Then I could also look around adn see if they left the cutout plug in the tank.

I think KZ uses rubber push- in connections. The fitting pops into the hole in the tank, then the pipe for the toilet (or vent) is then pushed in the center of the fitting. This fitting has an internal lip that should stop the pipe from being pushed in to far and creating the problem you probably now have. Pull the flange loose and try to gently pull the flange up, If I have guessed right, it will pull up. Once it's up aways gently slide it back down, you should feel it stop when the pipe hits that internal lip in the fitting, then measure how far the bottom of the flange is from the floor. Pull the whole mess out and cut that amount off the bottom of the pipe. If I didn't guess right, then KZ somehow jammed the pipe down thru a glue type fitting & a new tank might be in order, as I have no idea how to get down into a pipe and cut it internally or how to get the cut off piece out.  |

nvguy, thanks much. I will give it a go this week sometime. Hoping it slides up and I can get this issue fixed.

We have an RB261 and have filled the black tank almost to the top, or at least all lights lit on the sensor panel. I agree it seems like the sewer pipe from the toilet into the tank is into the side, not into the top. We had a toilet paper jam once and while shinning flashlight down there it sure looked like a 90 degree elbow that turned into the tank. Fortunately so far, no problems filling and emptying the black tank. 90% of the time I use the black tank flush.
For us, we try to use a lot of water to flush, and minimal toilet paper quantities.

That's the way our 261RB is set up too. A 90 degree bend in the toilet down pipe. I had thought the black water flush was on the top of the tank, turns out it's on the side opposite of the toilet. We also had a paper clog early on but haven't had an issue since. Our previous trailer had a problem with sewer odor when flushing. Our dealer installed a Lippert 360 Siphon RV Vent Cap that took care of the issue. When we started having the same issue with the 261RB I had one put on this trailer also. Works great and never get that smell any longer. |
