There’s no doubt about it – a nicely sweated copper joint in a piping system can bring a tear to an old plumber’s eye. Perfectly sweated copper joints are still, even in 2017, the mark of a skilled tradesman, a plumber who can get the job done leak-free and leave his customers with a little bit of art hanging on their walls or, perhaps, hidden behind drywall.
Over the years, different ways of joining copper have evolved. You’ve got your soldering and brazing, of course. You also have tools that will press a crimp in your copper, thus making a good, solder-free seal. This is perfect for large diameter pipes and in areas where you might not want to be soldering.
