Water Supply

[Walkerpe]

Just purchased used Skyline Park Model, it has 3 pex water lines, looks like the main supply line is white, there is s red line and a blue line, the previous owner did not know what they are for, any help greatly appreciated!

Usually hot (red) and cold (blue) supply lines. Just guessing here as I am NOT a plumber

I agree, pretty sure the white is the main water supply into the RV. I sm thinking the red and blue could be used to supply hot and cold to an outside shower or sink... They are just capped off, no valves.
