Blue Line exiting frame behind tires

[RVFun4Us]

I noticed the other day that there is a blue colored line exiting the frame on each side of the 3270 we just bought in February. The door side one comes out right behind the rear tire and the off-door side comes out in front of the front tire almost under the refrigerator. Each line just protrudes about a half-inch and has a white plastic 90 degree drain on the end but there is no valve to open or close. At first I thought the off-door side line was a condensation drain from the refrigerator. Then I found the one on the door-side which confused the situation. Does anyone know the purpose of these lines?

Those are probably the fresh tank overflow lines. If you fill the fresh tank, when the tank is full, water will come out one or both.

They are definitely your fresh water tank vent lines

Thanks Dan and Jerrod. Did not have those on my old coach, 3055. Good to know.

My Anderson valve has been leaking by the seals and filling my tank while we are hook to city water, so after a few days of being hooked up I have water coming out of the lowest vent.
I also had problems with all of my fresh water "when full" leaking out of those vents while traveling so I put shutoff valves on both sides.
I have to be real careful to make sure there open when I get to my destination.
Now I only close them if I'm traveling will a full tank for camping with no water hookups.

Jerrod,

Nice fix for that problem but see what you mean about forgetting to open when camping. That could lead to big problems. Anyway that you could get the leaks (seals) fixed/repaired so that would not be a problem? And yes, that is what my mysterious blue lines look like.

New Anderson valve will be here today. Heartland shipped out to me last week.
