Black Tank Washout Problem

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

    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.

    If I had to "guess" it appears that the hose which would put the water in the black tank is not connected to the black tank ???? 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.

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

    1. I know my comment will open a can of worms.

    2. I do not know why people washout blackwater tanks. Leave a few gallons of water in the tank and drive down the road and it will wash itself. If there is no place to dump after the drive home simply leave the small amount of **** in the tank. If it dries up over the winter (it probably will not) in the bottom of the tank no big deal. Again a few gallons of water in the tank on the first trip next year and it will be ready to dump when you get to the campground.

    3. The sensors are not going to work most of the time anyway.

    In summary, I would not do anything. I have been FT for 10 years. Before I FT I "summer camped" for 15 years. I never washout my tank.
