Best FLUX!

REX Member Posts: 29
I am back and forth with this,for now its oatey #95 or Utility brand. Olny thing with utilty brand is it does not have a nfs-61 approval for potable water...neither have astm B-813,ergo thay are not water  soluble. Water soluble is inferior flux and I wont use it. Though i must say some photos i have seen showed some bad dammage to copper by the flux causing pin hole leaks....never happened to me. I say some places must have water conditions that speed up erosion of flux/copper...further more i say always use L/k copper for water,not M. What do u think?
