Hi everyone. Having some minor issues with my Winnie 22m Minnie Winnie. It appears there is something leaking from the top of my black water tank. Here’s the thing.

It only leaks/seeps when I’m plugged into city water.

What do you guys think it can be? Trying to link a pic but it’s just water dripping down the side of the black water tank.

LOL. that just happened to me!
I thought it was the black tank also. I shut the water off and it stopped. So it's not your tank, it's a broken water line inside your coach.

Right above the black tank is where the small water lines run inside along the wall. You should have a raise along the wall inside where the nightstand/cabinets are next to the bed on both sides. That's where you will have to look to see which water line is leaking.
