Extra drain from where..??

[Davkat]

First time winterizing our 2021 Montana 3121RL I have a blue drain hose coming through the center of the underbelly just behind the rear axle under the kitchen. What is this and it is not the fresh water drain that's further back. I don't want to miss something that needs drained. Thanks Dave

Maybe the water line going to the refrigerator? My 3791RD has a valve under kitchen sink that turns on/off water that goes over to refrigerator for ice and cold water. If you close that vale under the sink and remove the cap from that blue drain , it will allow the water to drain from the refrigerator line.

Yes, low point drain for the fridge.
