"C" Channel and Water Leaks
I'm wondering if anyone has seen the construction details of the C-channel on 90's era rigs. My question is whether the C-channel "trough" would contain a leak that came down inside the wall and then direct it to a joint or seam in the channel, either at the door frame or where the channel must curve at the front and rear of the rig. To date, my leaks have only shown up on the inside floor at those locations.
Do the hold-down bolts have a washer or maybe even a glob of SikaFlex that would prevent water soaking into the plywood beneath them? Are the only joints in the C-channel in the aforementioned locations?
The reason I ask, is that there are considerable areas of my rig where I can not readily check for moisture at the wall/floor juncture-- along much of the street side, where a cable chase covers it, and back under the kitchen counter (beneath stove and furnace).
The concern is, a small but ongoing leak, that just wets one of these hidden areas and rots the floor where it is attached to the C-channel. Do I need to be checking every linear foot of my wall/floor juncture with my moisture meter, no matter how difficult the access?
