Small Clear Tubing Running Into/From the Fresh Water Tank Still has Water Visiable after Winterizing

[Deleted User] · November 2016

I just finished winterizing for my second time, and I'm still seeing water inside a clear small diameter tube that feeds into the fresh water tank. Does anyone know how to get this water out or does it not matter? I couldn't really get under there to take a photo. I used the blow out method first, then I put 2 gallons of antifreeze in the fresh water holding tank and ran the water pump to distribute it through the system, but this clear line isn't being affected at all. Any thoughts on how to clear this, or is it ok to just ignore it? Thanks

It sounds like you are describing the fresh water tank vent. It exits at the small hole just above the filler (see photo below).

I doubt a little water in there will hurt anything, but if it makes you feel better use your lungs and a bit of tubing (or an air compressor) to blow a few good puffs into that hole in order to clear the line back into the tank.

THANKS SO MUCH!!! I never would have figured that out!!! I do have an air compressor, and yes, it will make me feel better to blow out that line just because I want to win! hahahaha

On a related note, I always carry a small piece of soft tubing precisely for this purpose. When water backs up in that vent line, it tends to impede filling of the fresh water tank. Tilting the front of the trailer up supposedly helps, but for me this is rarely a convenient solution. Blowing the line out usually does the trick!

ScottG - I've found if I grab a handle and rock the T@B seems to clear it also but I may have to get a short blow tube in case.
