What Flux and Solder are the Plumbing Tradesmen using?

[alan8376]

What are the plumbing trade using for copper pipe work joints solder and flux?

I have some cored solder which is better for electrical cables.

I have some Lead free solder but find it needs lots of heat!

Thanks

Cored solder is not suitable for copper pipework.I use lead free solder and LACO flux.No problems.
