Winterizing

[Firemanjeff]

I have a 2015 trail runner 29 SLE TRAVEL trailer I am in a process of winterizing I have drained all the water out of all the lines, and have blown air through them. I found the water pump under a cabinet with a a sufon line coming out of I put rv antifreeze through this line til I had pink coming out of the cold water lines, my question is how do I get anti freeze into the hot water lines ? I have closed the Bypass for the hot water heater

If you set the winterizing valves correctly, water or antifreeze will flow from the cold water line, around the water heater, and through the hot water lines. With a 3 valve setup, you close the 2 valves on the hot and cold lines, close to the water heater, and open the valve on the line that connects the cold to the hot.
