Black tank spray connection

I have a 2008 3400RL. I have a leak when I attempt to use the spray connection to flush the black tank. It's like a loose connection somewhere as it connects to the tank...water leaks into the kitchen floor. How do I access the tank from the top or is that possible? I have taken the panel off behind the manifold, the panels under the stairs. The hose goes from the back of the manifold up through the floor with 2 or 3 others...can't find how to access where they end up.

Any ideas short of taking the whole pantry apart?

Thanks.

Do you see water dripping out from under the coach?

More than likely it is the vacuum breaker, which I just replaced yesterday. Some trailers have a opening in the pantry, mine did not, I had to cut a hole in the back of the pantry to get access to the valve, mine was located 63 inches from the floor and 13 inches from the outside wall. I very carefully drilled a 1 inch hole in the back of the pantry, make sure the pocket door is shut, at that point I could see the plumbing and cut a hole to access the valve. Check out my thread on Vacuum Breaker, I posted a link to a Heartland site which has pictures of the valve and where it is located, they are very similar to the Montanas.

We had this problem and went to this thread: http://www.montanaowners.com/forums/...ad.php?t=39697 You will find sreigle's excellent pics and lots of info from many members. It was a real help for us. Our hole is behind the TV, so I put a piece of vinyl tile to cover up the hole. I put 4 small screws in the corners so it is easy to remove if necessary in the future.

I have the same problem with an 08 3500. At least I think so I have water dripping out when I flush the black tank. any one know where the valve is in a 3500. I'll do more tracing in the morning.
