You still use paste flux. I think the difference is the extra temperature it takes to melt the solder and lead would get soft and fall over around the joint. The new stuff will do that too but the timing is different. In my case I think it an old dog fighting the new tricks. I can get it to work and some of the joints look super. But sometimes it feels like you escaped and got the pipes to stick...

I wonder if a different flux is required for the lead free solder and that could be your problem? We've tried lead free solder for electronics here and not had any problems with it, but there the flux comes as the core of the solder wire. Don't know if the plumbing solder has flux core these days but it didn't used to do that you had to use paste flux. Tom [Non-text portions of this message have been removed]
