Recently took delivery on 2021 Isata 3 , figured it was time to un winterize it in case we can find somewhere to go.
When I unscrewed the drain cap I thought it unusual that a couple gallons of Rv antifreeze drained out. I wanted to test out the holding tanks to be sure of no leaks . Grey talk holds fine , of course it’s the black. So now on my brand new Isata if I use it I can leave a full pipe of sewage when I take the cap off prior to opening the valve.
I am looking for suggestions to solve this I have flushed a couple tanks of fresh water with same results.
