On our way back from Canada a few weeks ago, we started noticing abnormal odors from the wet bath. By the time we got to Houston and were moving the van into storage, not only were there odors, but small trails of water were snaking their way across the center hallway from beneath the cabinetry adjacent to the wet bath. Another repair was clearly indicated, but initially it wasn't clear whether the toilet or the plumbing and black tank system were involved in the breach. Here were the steps involved in resolving this.
(1) The first thing I did was flush the black tank better than it has ever been done before. I musta ran 50 gallons through that thing.
(2) My husband de-installed the existing toilet, which was a Thetford Aqua Magic V.
|That's the hole cut in the wet bath enclosure, and the black tank beneath it.|
|The plywood edge should not have been left raw like what is shown above, so I sealed it with oil-based enamel paint, which just happened to have been red.|
I could see no evidence of damage or breach, so we moved on to the next step, which was to fill the black tank very full of clean water, and cap it so that we could take a test drive and slosh it around really well, to see if any water emerged.

Ah, the Thetford. What an extraordinary piece of crap. Never have I seen a worse design in the entire universe of RV products, and I'm not the only person who feels that way. Almost simultaneously with our troubles, Roadtrek Life published this post describing his troubles with the Thetford, of which he reportedly had purchased three inside of six years (!). Wisely giving up on the model entirely, he replaced it with a Dometic 300, but not before explicitly showing what is so horribly wrong with the Thetford.

I finally got it when I visually examined our own Thetford. And then I performed this test.
|I turned the de-installed Thetford upside down on a step stool, filled that interstitial space full of water, and left it overnight. And this happened.|

Amazon). But given our fit constraints, we couldn't find a better, higher-quality choice.
|^^ This is what I was feeling like when I was reading low-ended gravity toilet reviews. No model was reported to be free of problems.|
|You can see how close the rear hinge is to the back wall. There's no way we could get a larger and more expensive toilet model in this space. But that's not the only size issue - it's not as short as I would prefer, either.|
Sigh. What a pain. If we go to all this trouble and spend the money, it sure would be nice to have a problem solved long-term, and a reliable outcome at the end of a project such as this. I don't think that this model of toilet represents an auspicious completion, but at least it's an improvement over that God-awful Thetford, for the time being.
