I can't really add much to what has been said, but think of it this way. Yes, it may appear to be fine...now, but the fact that you have questioned it indicates you have a doubt. You will never be certain if it will hold 50 years, 50 days, or 50 minutes. Several year ago I had a new 1" supply line installed. Three or four years later, I was working around pipe where it entered the house and leaned a ladder against it. The connection, including the shut off valve, suddenly blew apart. 90 psi through a 1" pipe delivers a huge amount of water. Having no way to shut the water off myself, I had to wait for a city water department to dispatch a worker to shut the meter off. It seemingly took forever and all the while my basement was flooding. I found the problem was that the valve at the meter did not 100% stop the water, and there was evidence of faulty soldering due to that small drip. I since have obtained a curb key of my own to shut the meter off, and I also do not mess with trying to fix a leaking solder joint... I redo it 100%.
