To be fair, lead solder is far far far less risky than last piping

Well, it’s not been legal in the UK since 1970 to sell or install lead plumbing.

And the official Department of Water Inspectors (https://dwi.gov.uk/) reported only 50 cases of lead pipes in last year’s inspection

Yeah that’s not been true for about 50 years.

We replaced all our lead, and it’s a legal requirement to if you find a lead pipe in a system, replace it no matter what (even in listed buildings) or disable the outputs entirely (the latter is more common in VERY OLD buildings, with people then adding a new system somewhere else, sometimes with exposed pipework rather than having to potentially damage walls.)

We also just don’t do hot water tanks any more usually, instead doing on-demand boilers.

Does mean that the hot runs cold for about a minute, but it balances out

Impossible, as the American band Rammstein once said “We’re all living in Amerika, Amerika ist Vunderbar”

And then the rest of the song is in German Far Western Pacific American

That’s only true in America, where your Health and Safety Standards are shit.

Might be true in parts of Africa and China too, along with other places with a bad standard of human rights.
