Black tank flush.

Last year when dumping my tanks, I was trying to us the black tank flush and got water inside the trailer and onto the floor. So, didn't do it again last year, but tried after a 3,000+ mile trip and it still leaked this year. I took the toilet off and looked around, but was unable to find where the darn thing attaches. We have a 2012 Eagle SuperLite HT 26.5 RLS. I just can't seem to find any openings that would seem to work. I haven't climbed under the FW to see if there is an access "hatch" that would allow me to look around up around this connection. Any help would be greatly appreciated.

I think your set up is exactly like mine and I had the same problem. It is the backflow preventer which is inside the small box located behind the toilet. There should be an access panel inside this box where you should see (or feel) the leak and the backflow preventer. Mine was still under warranty so the dealer fixed it (about 3 weeks ago). If it were not under warranty, I figured to take off the outside shower box to gain access to the fitting. These things go bad quite often so if you end up replacing it yourself, get a good one.
