For years I worked at large plumbing companies that routinely used galvanized nipples and 90's for the tub spout, with the rest of the home being plumbed in copper. For the first second or two, you would get a little rust.
The pipes lasted forever it seemed, but for that second or two, a little rust.
Many homes in up until the 70's were plumbed entirely in galvanized. It was one way to get enough iron in the diet.
You can buy those homes, and they get rust from every fixture. If you grow up in an older part of the city, those people just think it's normal to see a little color that goes quickly down the drain.
So..........what else is happening in your life. Heard any good jokes lately? Is everybody healthy?
