Who knows... I haven't seen those around here yet, ours are not pre-tinned.
I don't know what the fuss is about anyway, soldering copper fittings is
so dead easy with just plain wire and a tin of "soldering paste" (the flux
only not the one with tin inside). I never understood why they even found
it necessary to invent the solder bearing paste, and i certainly don't see
the need for pre-tinned parts. But i guess plumbers charge so much these
days they have grown lazy of cleaning the copper before soldering. Well, i
sure don't need one of them anyway...
Won't be long and the copper plumbing will be gone. They make everything
plastic (PP) now around here, which is directly welded together. I don't
trust that crimped nonsense, and welding is fairly easy.
About your trial with the pastes, i reckon i might be curious about the
results, so don't forget to report in a few years time ;-)
