In mine everything apart from the kitchen tap was off the header tank.

Everything here still is of the header tanks (plural, 3 x 50 gallon
main ones plus another 50 gallon and a 30 gallon). Mains water is a
fairly recent addition to the property.

Although we cleaned teeth etc in header tank water for many a year with
no ill effects. I think.

No ill effects here, even before I cleaned the main tanks of the
detritus and dead animals.
