Those red/blue lines allow blow out existing water for storage or winterization.
Open them, pull anti freeze thru and then close them.
How would water get up and thru the system without using the water pump to pull it up and thru?
Now you have me confused Mel.
Hopefully this will clear up any confusion. The blue line and white line under your trailer is for the fresh water tank. The blue one is to drain the tank and the white one is the fresh water tank overflow. When filling your tank and water begins coming out the white hose, your tank is full.
The blue and red water lines in the storage compartment are the low point drains for the water lines in your tailer. I love having valves and not caps on these lines.
The red arrow in this picture points to the white tube used for drawing antifreeze into the water lines of the trailer during the winterization process.
