Hi all
By now I think I've established that the rubber expandable plugs are by far the most common / industry standard for winterizing lines.
However, I recently watched a video from a guy in the industry who made a good point, conceptually. He contends that threaded plugs are safer because when the water level is lowered to approx return level, when the water freezes it can grab the wing nut of the rubber plugs, ripping the plugs out and hence opening the line.
Can't find the video any...
