Black Tank Washout Problem

[FloGrown]

Hello Everyone,
New to Forum. Have a problem.
We recently purchased a Coleman Travel trailer new from Camping World.
We have camped a few times since purchase but never used the black tank flush. Last time we went out decided to use the flush port. Hooked the hose to the port and turned water on. Water immediately started pouring out from bottom of camper. Clean water. Looked underneath and saw a white hose around 5/8" dia. hanging there. Also saw a white threaded port attached to what I assume is the black tank. I can see where the black corrugated plastic bottom has been cut out. My thinking is there was a problem with that area, they cut out the bottom to access that and I reckon they never fixed it and then sold me the camper. Take a look at the pics. Let me know if anyone knows what is going on with this and what parts I need to fix it. I would take it back but I'm sure it will sit there for a while and I can probably fix it easily if I know what to do.
Thanks for any advice, suggestions.
Brian

Yes, I would suspect a previous problem with the black corrugated material cut. Mine was cut and I suspected the same. If you hooked it all up right and water poured out, I would try to determine why that hose is not connected to that connection.

I had a fresh water fill tank that almost exact thing happened to. Same problem.

a tech stole a part for another trailer

Is there supposed to be some type of "backflow preventer" there.

I see I wasn't supposed to post this in this section but I don't know how to move it.

You'd be better off fixing it yourself or paying a mobile tech to do it.
Avoid having CW do anything.

You need to remove what ever they used to plug the fitting in the tank.
Then you need another section of the pipe and a coupling.
Attach the longer line via a 90 degree fitting to the tank fitting.

I reckon you should take it in for repair.
