As a fellow Canadian, I send along this advice. The 1/2 inch copper fittings in Canada did not fit the 1/2 inch copper pipe in my 74 Airstream. In talking to a dealer, he had run into this problem. The fix that I developed was to take a plastic compression fitting and a very fine round file, and create a larger fitting that will fit over the existing copper pipe in the trailer.

Only took 5 minutes once I got the idea. If you have a lot of leaks, replace all the copper with the grey plastic pipe that is freeze rated. While at it put in a valve to isolate your hot water tank because some day it is going to start to leak.
