You don't need a pretty wiped joint to join lead to copper. Merely a
decent seal between the two.


Simply running solder into the join would not have passed inspection for
a professional job.

Then you need an inspector who understands basic metallurgy.

I was going by old contract specifications (and before that bye-laws).

The solder had to be built up in layers to give
the thick "bandage" to guard against leaks. The wiping wasn't just to
make it look pretty.

Solder in layers isn't going to seal between layers.

I was wrong to say it /had/ to be in layers but I have seen it done with
successive pourings. It's all molten so I don't see why it would not seal.

Are you confusing it with plumber's metal?


Plumber's metal is solder.
