The way yours is put together looks different than mine. I have a 90 degree pipe connected to the gray hose, looks like you do not. I think it is a bad design and no real clear cut way to fox other than a redesign. I would think the factory would have a better idea of how to fix it. I would take mine in as it is a warranty issue but the appointment time is 2 months out. We use our RV all year long as the winter weather here is not that bad. Not sure what is the best way to cover the hole back up as I got rid of the stupid black bag cover.
