I was sweating some new water lines in and ended up with a couple leakers. I did about 50 joints and they all held but these two. I have drained the water, cleaned and fluxed but I can see the solder is not "sucking into" the joint. I think I have all the water out as I don't have any problems getting the copper hot enough to melt the solder. Any tricks to this? Thanks
