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.

You have provided no evidence of that.

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.

You are comparing a but join where solder is built up as a bandage, and
a join where a copper pipe enters a lead pipe for 25-50mm.

They simply do not compare. It suggests you have never connected a
copper pipe to a lead pipe. There is no need for layers to guard against
a leak.

I have indeed never sweated a copper pipe to a lead pipe - because I
don't have the skill to do the job to a professional standard and there
were modern alternatives available to me. I have seen many such joints
(to iron and brass as well as copper) done by professionals - ancient
and modern - all of which were "wiped" into a thick layer. And even
seen a few done. I was told they leaked if the lead was not built up.
But you may of course be right that it was unnecessary.
