OK, here’s one I haven’t seen discussed. I have a 2019 Unity TB. The fresh water tank and water pump are under the passenger side bed. The service center and winterization valve are over on the driver’s side. If I understand the plumbing correctly, the draw from the water tank goes over to the service center, through the winterization valve, and then back across to the intake/suction side of the water pump. When you switch to winterization mode, the suction is switched to the open tube in the service center.
So what happens to the water line between the tank and the winterization valve? There is no specific procedure to clear water out of it or fill it with pink stuff. How does it get winterized to avoid freeze damage?
