I've been following this for a while and keep seeing reference to "brazed"
I've never seen a brazed joint in water pipes. Soldered, but never brazed.
The temperature for brazing is much higher than soldering and would be
enough to show some serious oxidation on the copper. Brazing would require
the copper to be at a "cherry red" heat to get the stuff to melt. In most
homes the amount of heat required would cause charring on any wood near the
It may not be permitted, but I'd trust a good brazed joint any day over a
compression fitting that can corrode. I've had compression fittings
completely lose contact with ground rods.
