Welcome.

Check the anti-siphon valve on the Santi flush system--it is likely installed backwards.

OK that’s kind of what I was figuring but I thought it might be a check valve installed backwards somewhere but I cannot locate anything but hoses would you happen to know where that Val would be located ?

Not sure where that is as our Axis doesn't have one.

If you can I'd try to trace the plumbing back from where you hook the hose up to the tank (most likely will have to crawl underneath to find it).

You could also call Thor and ask for the construction drawings for your unit--make sure you have your VIN handy.

I have one on my chateau 31E as well that did the same thing. A small frog had taken refuge inside the connection and became a blockage at the elbow. Removed said frog from the system and were working again.

Yes there was no screen protection on the inlet. Fixed it with a hose washer screen you put in at the connection.

Have fun trying to locate it. Mine on my 29h is in the interior, wall next to the shower about four feet above the floor.
The only reason I know this is that the paneling buckled the first year in NC camping during hurricane Mathew.

Glad to hear that this was an easy one: once the culprit was found!
