    Help. I purchased a used 2016 Columbus 5th wheel from an individual and unfortunately no training on how to do anything. Im very new to the RV community. I'm struggling with dumping the Black and Gray tank. My control panel shows Gray tank 1 gray tank2 and Black tank 1 and Black tank 2. The water is backing up in the shower when running water facet in the bathroom sink. When running water in the kitchen sink there are no issues. I have had issues with the toilet but feel Ive isolated that issue to being in the pipe before it reaches the black tank. Hopefully someone can help me. Due to covid, ive been unemployed so taking it into a rv repair shop just isnt an option at this time. help

    After using our black water back flush after draining black tank religiously for 2 1/2 yrs it has suddenly stopped working. Water goes into hose but does not enter black tank. We cleaned out the screen on the outside outlet but from there we have no idea on what step to take next.

    If you have your black water tank directly below the toilet, then you can use our method. We use a Flexible Swivel Stick, that is inserted through the toilet’s, hand-operated type, open flush valve, on a ten foot hose, that is connected to it’s fresh water supply by a double valved Y connector, that goes in the window nearest the bathroom. Also a Sewer Solution (SS) system, connected to it’s water supply through a very short hose to the other branch of the second valved Y connector, that has its own back-flush feature. We also needed a 7 inch sewer extension, so the 1 inch SS drain hose is lined up with the utility compartment port. My wife handles the inside duties while I man the outside. We get all the level indicators back. After the dump valve is closed, toilet flush valve is left open for 1 1/2 minutes and the Orange TST tank treatment is added. I then dump the gray water tank. (Back info, I have my water filter connected directly to the fresh water intake, then through a valved Y I connect the fresh water hose. All inside the utility compartment.) I also installed a Cyclone Sewer Vent on the roof in place of the standard black tank vent cover. We have no odors. Hope this offers invite.
