Do you think plumbers would bother to carry two types and (hopefully) use accordingly?
You can still buy lead solder!?

Hmm.
You have a point.
I wonder what's in Yorkshire fittings?

All true, but IMO all this fuss about lead in the solder used in plumbing is probably an example of an almost ludicrous degree of bureaucratic 'ultra-caution'. When one remembers that, for centuries, many people spent their whole lives drinking water that had come through pipes made entirely out of lead, the tiny tiny bit of exposure of the water to the solder joining copper pipes surely fades into total insignificance?Water hardness is an intrinsically related factor. Hard water = scale in the pipes = less lead in the water. Soft water = no scale + lower pH = more lead in the water.People other than myself will have to judge whether any of that applies to me (in my case 50-60 years later)

I was told that you weren't going to be able to buy it.
Which is why I've got loads of it.

Then why is lead free solder easier to get hold off. I have up till now been using lead free silver solder with a rosin flux pen - no fume extraction and all is fine for me.
And how about the solder with built in flux where it is claimed you don't need to use any other flux?
Last time I had him around, my plumber carried leaded solder for doing larger joints on heating systems. Simply easier and more reliable when you're working with 28mm and bigger.
Ok. Good.
Just a point regarding petrol mentioned.
Unleaded petrol (95 octane) does contain lead; it just does not have any more added as did four star (98.) and five (100).

Yes. Green reel = lead free, Yellow reel = leaded. It's the same gauge.
The only company to jump on the lead free bandwagon for DIY electronics were Maplin. I guess they felt guilty after 40 years of selling the leaded stuff.
Do you mean that it has a little naturally occurring lead in it (which wouldn't surprise me)? AFAIAA, the addition of any tetra-ethyl-lead as an 'anti-knocking agent' (resulting in higher octane fuels) has been completely banned in nearly all countries, other than in aviation fuel.
Tetra-ethyl-lead was a particular problem since, being an organic molecule, it gets into the human bodily much more easily than does 'inorganic' lead (such as the inorganic lead salts you might find in tiny amounts dissolved in tap water when there is lead plumbing).

No, Don't be silly.
Seriously, I don't know the technicalities of the process.
Merely that when unleaded petrol was introduced no lead was removed from the product, it just ceased to be added.

My phone is obviously crap at refreshing the pages properly!
Solder ring fitted are unleaded. You used to be able to get both, but then manufacturers phased the leaded versions out.
Quite so - and, as I said, I don't know whether any 'naturally occurring lead' remained when then stopped adding it. The important point of what I said is that what they were adding (tetraethyl lead) was dramatically more hazardous to man than any lead in tap water which has flowed through lead pipes, let alone thgrough lead-soldered copper pipes.No, Don't be silly.
As for the semantics, I don't personally think there is anything wrong with using the word "unleaded" to mean "no added lead" ('but there still might be some there'). By comparison, most people would take "unsalted peanuts" to mean that no salt had been added, not that peanuts themselves contained no salt (which they do, as does virtually anything else of biological origin), or that all salt had been 'removed' from the nuts - if you wanted to convey that latter meaning, I think you'd have to say "saltless", 'salt-free", "de-salted" or something like that - not "unsalted". .
