Winterizing valve below the wardrobe
Our owner’s manual says both the 27' & 25' front bedroom Classic models provide exterior water service via a hose bib located fore on the RS, DS, in an exterior under-belly water connection locker.*
This location is an unheated area can freeze. According to our owner's manual, an interior shut-off valve exists below the wardrobe closet floor.*
I have looked and tested the only valve accessible in that sub-closet location. The line appears to go forward toward the utility locker, or to the shower. However it has no effect on the output of the exterior hose bib fitting or the shower. This is possibly due to a meaningless tubing setup bypassing the valve. In the absence of additional valves, the by-pass around the valve of an assemblage of white tubing & fittings makes this valve useless.*Is the valve defective & non-functional? Or, am I reading the tubing incorrectly?
The lines are joined by "high tech" ferrules. I have no desire to purchase such a tool & supplies.
