Anti-Freeze Leak and White Water Lines

[joegpetro]

In December 2014 I purchased a 2015 Montana 3610RL. It was winterized when I picked it up and I noticed nothing out of order. Recently (February 2015) when looking in the outside storage area under the bathroom area, I noticed a small puddle of anti-freeze directly under the four water lines going up to the bathroom sink. All four lines (red, blue and the two white ones) had drops of anti-freeze on them and from the slope of the lines, the leak had to come from above in the bathroom sink area and dripped down on all four lines. This small puddle of anti-freeze was not there when I picked the unit up in Indiana nor has it been there again since I wiped it up about two weeks ago at home in Montana. Other than knowing the leak came somewhere between the bathroom sink fixtures, down through the bathroom flooring to the outside storage compartment floor, I'm at a loss as to where the leak originated or why it leaked when not in operation and under pressure.

I would appreciate any feedback on this issue. Also what are the two white lines are for? They run along side the red and blue for as far as can be seen, from under the bathroom sink, down through the flooring and then horizontal towards the rear of the unit. They terminate under the bathroom sink near the hot and cold faucet connections. Both white lines are capped at this location and their use escapes me. Maybe they are vented and the anti-freeze leaked or escaped from that location?

Thanks for any help.
