|In response to Re: copper sweat joints|
Normally that means the joints were not made properly and water is seeping through the joint. Not enough to leak, but enough to evaporate and leave the minerals behind.
: 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?
