On your unit (a recent 27' FB) the anti siphon valve for the black tank flush is at the back of the wardrobe. Remove the little "step looking" thing at the back of the wardrobe by removing the dozen or so screws and two pieces of laminate and you'll see it soon enough.

I have a 2014 Sport 22' and have hooked up the sewer flush three times. It has leaked all three times. My leak is much worse that yours. Today I turned the water on very gently and it still leaks out the bottom of the trailer. Will call Holiday World tomorrow and arrange for a repair.

Leak Fixed

Found a solution to the problem: Traded it in for a 2016 Flying Cloud.

Well...that's ONE way to sell a new trailer... sell a defective one and then later take it back in trade for some simple fix...
The backflow preventer is a building code requirement for hooking up to city water to flush the black tank. This is because code-writers believe you are likely to leave your hose hooked up and the valves open and let a germ climb backwards into the city water supply. NOT LIKELY to happen!
Since I only hook up to my own private well...and/or a campground supply...with a dedicated garden hose.... and since I only do so to pressurize the flush system and never leave that hose connected's NEVER GONNA HAPPEN that a backflow preventer would prevent anything except the flush-system's proper operation.
So... after I found the insect nest in the backflow preventer that blocked the flush system from working... I removed it and replaced it with a "shark-bite" elbow, which was a very simple matter: Cut the PEX tubing, insert the "shark-bite" elbow... and FLUSH anytime/everytime with no problems.

2010 Flying Cloud 20 here, this connection is under the bathroom bench, looks like I need to remove the benchtop to gain access.

I can see the leak through the side panel access, but is too tight to work on. I hope it's a simple gasket issue. Is there an easy way to remove the bathroom benchtop? it appears I have to disconnect the waste and 2x tap hoses, before I can slide it out?

When we picked up our 2016 Classic last Janurary, it was winterized and we left it that way until we went to Florida the 1st of Feburary.
The first time we hooked up the black water flush it poured water. Not knowing what the problem might be I didn't try it again. I used a hose directly into the toilet until I got the leak fixed.
I made an appointment at Jackson Center and they discovered that a hose was loose, they fixed the problem and we were on our way. Worked great after that.

I have a 2011 27 FB with a busted back flow prevent valve, cheap is right but only in quality. I got a price from the Airstream dealer in Canada, CAD $ 102. I will replace it with an elbow as well. It is accessible from inside the closet where there is a panel that is held in place by 5 or 6 phillips screws.
