New Jayco Owner

Hi my name is Tim and my wife and I just bought a brand new 2017 Jayco Jayflight SLX 29 ft Travel trailer. Although we have owned other travel trailers this is our first brand new one. We are quite happy with it so far. I do have a question though, earlier today I was under the sink in a cabinet where the water pump is and noticed a clear tube coming off one of the lines and one end was not connected to anything (see picture ) is this suppose to be like that ? I could not find anything under there where it looked like it was suppose to be hooked up to. Is this just a "breather line" ?
Thanks for any help ya'll can give me.

A big welcome to JOF.
We don't have the same RV as you but that line is probably either an input line for winterizing or a vent line as you suspected.

Welcome and congratulations. The clear line you have is used to winterize your trailer. The loose end is inserted into the antifreeze bottle and the water pump is used to suck the antifreeze and pump into your plumbing system.

Congratulations on your new Jay Flight and welcome to the forum.

That clear line is a 'suction' line for drawing in RV anti freeze into your water lines. It is open at one end.

Welcome to the forum and congrats on the new Jayco! You have piqued my curiosity. Next time I am at the storage lot I'll have to check for that hose in our TT. Have fun with your new trailer and happy camping!

Welcome to JOF.

Just to expand on what the others mentioned, that clear plastic tube is for winterizing. You will notice there is a valve or tap under the sink and when you turn it and then turn the water pump on it will create suction through that clear plastic tube instead of sucking water from your fresh water tank. Just stick one end in jug of antifreeze and run taps (in proper order) with pump on and it will fill your water lines with antifreeze. Usually the two ends for oval tap handle will be in-line with the flow. Your hot water heater will have the same type of valve to bypass your hot water heater for winterizing. This is my first trailer with factory installed winterizing kit as well and it makes winterizing much easier than funneling into the freshwater tank !
