copper sweat joints
Posted by willie on April 05, 2002 at 18:50:16:
I was looking at our plumbing in our crawl space. I noticed that the sweated copper connections all have a white substance around them rather than the dull silver color of solder. What might be the cause of this? Did the person who did the work use too much flux? Is this a problem?

Thanks.
