Wow, I'm glad that I didn't trim my line set. I did not want to do any flares.

Sometimes, a over-torqued flare can last a while. I saw one in thick walled copper
for the water pipe feeding my house. A coupling was installed about 10 feet deep, in my front yard, in 1956.
It started leaking in the mid 1990s...
The flare walls were very thin, like a foot-ballplayer used a long-handled wrench to make them.
I guess the water-hammer got to it..

There was a rock the size of a VW Beetle sitting on top of the pipe, so that
fitting cost us about $1,200 to replace.
The plumber said, they cranked down on the coupling nuts too hard.?.

So, have you done any pressure testing yet??
