[TowerTalk] Water in Conduit...

[Perry K4PWO]

Another factor in my case is that the outside NEMA box that terminates the conduit at the house is at the unheated attached garage.  The coax/cables leave the rear of the box in an 8" diameter duct through the wall.  Once in the garage, they are in a framed cable tray that continues to the ceiling of the garage where it goes into the attic space.  Since there is a long "thermal buffer" that may be the key to my dry conduit.  As I said, seven years and no water.

Here’s a data point: I have used underground PVC conduit for many years with no water ingress.  There are two runs, about 100’ each.  Both are 3” PVC, chemically welded and plowed into the ground by a sprinkler company.  After 7 years, I pulled the cables out and they were dry as a bone.
