Roof cleaning and bubbles

[Rebel702]

Thats good news on the repairs. Sorry to hear it gets put away for several months. I was surprised to see an antifreeze connection on our new trailer. It is located by the black tank flush connections. Do you have that on your trailer?

Yes we do and that is what I used to winterize. There is a shut off valve on the line from the fresh water tank just before it goes into the pump. Block that line and the pump picks up the antifreeze from the line to that external fitting. Two bypass valves at the hot water heater that have to be blocked and a third valve between the hot and cold water lines opened (also at the hot water heater) and that's it. Took 3 gallons.
