Blackwater Flush problems

I have a 2014 351DS. I recently had the dealer fix my blackwater flush line under warrantee. The dealer said that the line was installed wrong. I never double checked the fix and just recently went to use the system. Instead of the water running into the blackwater tank I get clean water spewing out from above the blackwater tank in an area that is inaccessible above the hotwater heater. Of course my warrantee is now over as of a week ago or so. I am not sure what is wrong. Has anyone else had this problem.

Because this reads like it is a failed warranty repair you are still covered because you opened the claim while it was covered, hardly your fault the dealer did it wrong.

Push them on it.

I have the same problem with mine. When I took it in for a few other things including that, the dealer told me they would have to take out the refridgerator and stove and cut a hole in the floor to fix it. I told them I thought there should be a better way without cutting up my MH as I had read of others with that problem. They told me since it had been listed as a problem before the one year warranty ran out they would take care of it the next time I was in.
I contacted Kevin at FR and he told me to have them call him and he would connect them to someone who could tell them the correct procedure to fix it.
I haven't been back in to get it taken care of yet but it seems as if yours was an was an issue before the warranty ran out they should go ahead and fix it.
If not I would contact FR and discuss it with them as the black water flush leaking is a known issue.

Wonder if the leak could be the result of a faulty vacuum breaker valve or related connection?

I had a similar problem, and found that the vacuum breaker valve output tube had cracked and separate at the 90 degree output fitting.

My valve is located behind the shower surround right behind the circular access cover under the diverter.

Just a thought - good luck.

Thanks for the info everyone. Looks like it is something I am not interested in fixing myself, so I will have to definitely get with my dealer to get it done under warrantee hopefully.

Our 2014 351 is in for warranty repair on same problem. When using black tank flush clean water runs from over water heater into compartment with inverter. My understanding is its leaking on side of black tank where water line connection is going into it. I think they removed the water heater outside shield to get to it. The vacuum breaker leaked earlier and I had FR send me a new one. But it leaked inside under sink cabinets. The breaker is located behind the drawer beside stove. I've been told they have fixed it. I will be sure to give it a try when get home.
