Aqua hot antifreeze leak
I have antifreeze leaking from above the wet bay when I use the heat. Has anyone else had this problem? How is the best way to go about trouble shooting?

What year RV and floor plan do you have?

Most common leak is the hose from the recover tank to the AH. It is cheap clear plastic that gets brittle and cracks usually underneath. If it is no longer clear and burnt looking, it is time to change it. The braided clear hose sold at Lowe's by the foot is better material. It takes 5/8 in hose.
Posting the year of your coach does help in trouble shooting problems. If your coach is newer than a year, likely that is not the problem. The year will also help if it was one of the years with poor hose clamps which many of us with older models have changed.
Also is it engine antifreeze or Aqua Hot boiler fluid?

Leaking "above the wet bay" would probably mean that you have a loose pex to copper or pipe hose clamp up there somewhere. My guess would be to the register that is in the bathroom. I think almost every Entegra floorplan has a bathroom above the aquahot and wetbay compartments.

Probably not same issue, but my expansion tank was leaking on a 2017. The tank itself. Fluid leakage can be hard to find since it can travel long distances to a low point. Just start looking wherever you can see for starters. Good luck and please let us know.
By the way, all it took in my case was a few pics and Aqua Hot sent me a new tank. No troubleshooting by a dealership, then Entegra, and then to Aqua Hot. Saved a lot of headaches this way.

If it is engine coolant fluid (most likely red) you can shut two yellow handle ball valves located on the left side of the engine by turning them to the position where they are not in line with the hoses they are attached to. One can be accessed from the rear of the engine while you probably will have to get under the engine to turn the other handle. I had fluid leak from the Aqua Hot engine pre heat pump. Of course it was summer time and Entegra had it corrected in 2016 by an Aqua Hot Tech during our PDI.

Sorry for the delay getting back. It’s a 2015 anthem 42rbq and it’s boiler antifreeze coming from above the wet bay.

I would take a look at what magic-carpet indicated as it is more than likely a clamp that needs tightening a bit; at least that’s what I’m hoping for, just something that needs a little ‘gute-n-tight’.

Update:
Leak found and repaired, no thanks to Entegra. It appears that someone screwed a self tapper right in to one of the lines above the wet bay at the factory when it was built.

But if that was done at the factory during construction, this problem has been happening for over 3 years already. Maybe it was someone doing a repair more recently.
Oh, and you can make your equipment always mentioned by adding it to a signature which you set up by accessing the User CP (User Control Panel) tab in the top left part of the web page. Always a good idea as it is always clear when you post.

Let me guess....you found the hole when you removed the aluminum ceiling tin in the wet bay? The screw was holding the tin and piercing the hose at the same time?  Either that or the silicone patch held in by the screw finally gave it up?

Bruce, had you been loosing fluid before the leak became visible? That is a strange one to show up 3 years later for sure.

Gary, it was done at the factory. This coach has always been located in the south and this was the first time the floor heat was used. So yes, 2 and a half years before this “screw” up was found.
And I added my info to my signature a few weeks back.
