I must say i am often surprised by practices in other countries. I've never heard of any of this stuff. I am probably completely uninformed or situation here must be very different. Like it seems you have to know so much stuff and have so many systems in place to have water... For example i live in appartent building with central water heater. I absolutely use hot water from it for pasta. Am is it wrong? And letting water to flow for 20s? Why?

If you have copper pipes with lead solder, or fixtures with brass (which will have varying amounts of lead), or lead supply lines from your city, the longer that water sits in contact with those joints/fixtures, the more lead it gets a chance to absorb. So flushing the line gets you 'fresher' water from the municipal line that hasn't dwelled against your smaller diameter dirtier pipe. Can be a big issue in schools for the first kids that drink from the fountains for the day. The water heaters, well, hotter water has higher solubility, so while it sits in pipes, could absorb more from the pipes.
