    Hook a water hose up to the nipple on your clear elbow that's hooked up at the trailer. Turn the water on full and let it try and clear up the blockage at the outlet of your black tank. May or may not work depending on how bad the blockage is. Since it's only been a few days it may work, worth the try.

    vSo, I just added some Happy Camper, I'm going to check in the morning. If no luck, will try the hose flush. If that doesn't;t work will call Camping World to see if the have either the Valtera or Rhino flush valve. If all else fails, Mobile RV guy. Will keep you posted.

    Thanks for the help!!~

    Close the valves
    Undo the sewer hose and hold it up
    Fill with garden hose

    Keep a high loop in it and reattach to campground sewer not allowing water to drain then open black valve and lift hose up to force water in

    Whittle, I only have a 90 elbow at the rv park sewer connection. No clear fittings att the trailer outlet pipe.

    They make a wand attachment https://smile.amazon.com/Yiliaw-Exte...s%2C204&sr=8-3 that comes with a flexable extension. You could run it down the toilet then turn it on to try to flush out the blockage. My son gave me one but I have never needed it.

    Steph ,We did that recently. After 5 years we got a big block, this block was making up for lost time lol.. back flushing did not work and neither did the tank flush so we tried that method in the video. It took a couple tries but it did work well.

    If it has been 3 days I can't imagine there would be enough in the tank to cause that kind of blockage unless liquids are leaking out of the black tank due to something not letting the valve close completely. You have done regular back flushes haven't you?

    Here is what has worked for us a couple of times:

    Open the black tank valve and then pull the gray tank valve. Close the gray tank after a couple of seconds. Opening the gray tank provides suction that can clear the blockage in the black tank.
