Same thing happened to me when I tried de-winterizing the Eagle. It's that time of year, and everyone is de-winterizing. I see a lot
of us newbe's (or a least new Jayco owners) are experiencing this same situation. Nice to see I'm not the only one who's run into it. Called for help here, and these good folks came to my rescue, as well. What they have suggested was exactly what needed to be done. Thanks, again, for your help!
Now that you've solved the water problem, I'm sure your next outing will be much more enjoyable. Happy Camping!
