Good evening. Got back from a run & found a fairly strong flow of water coming from under the Castle. In the hard to see pic, there’s a black hose - maybe 3/4” ID, to the left of the vertical blue lines. Pretty sure it drained the fresh water tank, & appears to have been sealed with tape - maybe Flex Seal…FW tank shows empty. I figure I will crawl under when the ground is dry & see if I can clamp a shut off in there.
