Thetford Aria Deluxe Overflowed on its own

This is a very bad situation, what if we were not in the RV, the whole RV would have been flooded.

There should be an automatic shut off of water built into the toilet that would prevent this from happening.

Some clarification is needed.

In most cases, the water pump is NOT IN the toilet.

Regardless, this is exactly why you should get in the habit of shutting the water pump OFF when everyone leaves the RV....any brand and model.

I recently had to replace the incoming water shutoff valve in my toilet because it wouldn't shut off completely; just the valve, NOT the whole toilet. About 1/4 the price.

And finally, assuming you have a gravity flow model with a big dump valve in the bottom......the quickest and best way to prevent an overflow would have been.......to flush it and then turn the water off.

Edit: One more thing: IF you were connected to "city water", there is no reason to leave the 12 V water pump ON. Several things about your story confuse me.
