This house had galvanized pipe on the supply side, fell apart and plugged a bunch of downstream hoses, gotta wonder what decade that hillbilly bs was made illegal
Thick black Cast iron Lasts longer than galvanized because it doesn’t rust like a puff pastry and because it’s thick.
The big Sewage pipes in this house are cast iron and likely as old as the home (1860’s)
Lead pipe is an issue here as well, that’s why in yea Olde times they said to take cooking water after an appliance used a bunch of water and then run it 5 minutes through the sink.
I no longer have a filter compatible sink (gotta fix that, drink too much bottled crap )
Oddly lead dates to before chlorine and it saved lives by keeping water sterile (hence its popularity). Sadly it also makes you nuts
