Black tank flush system leaking
Hello, We traded our TT for a 2010 Keystone Montana 3455SA last week. It has a black tank flush hook up in the convienance center. When we hook a hose up to rinse the black tank out, fresh water leaks...

I am experiencing the same thing with my Outback. It started last summer. I quit using it after flooding the camper twice. This last week-end I had the wife turn the water on at the spigot and I watched inside. Mine is under the sink.
Turned out there is NOTHING wrong with with the anti-siphon valve.
The problem is right where the garden hose attaches to the outside. Water came gushing out all around there. As the outside is sealed completely with calking, the water had no where else to go but under the cabinet inside the camper.
I was going to disconnect it, but we were still camping, and if I remove the outside fitting (where the garden hose attaches), I want to make sure I have access for a replacement and a calking available. As we were camping when we ran the experiment, I decided to wait till we get home.
If you can run a similar test, I bet you will find the water hose connection is also spewing water inside the camper. Nothing is wrong with the anit-siphon valve. I was ready to take mine off too and just replace it. That would have been a waste of time and money. Check the connection where the garden hose attaches (inside the camper).
FYI, Montana and Outback are both Keystone campers. I bet they use the same part for the black-tank flusher.
