Atoms gain electrons to form anions.
Atoms lose electrons to form cations.
Back in middle school, my chemistry teacher taught me a good way to remember whether an ion was a cation or an anion. When an atom loses an electron, it becomes positive, and when an atom gains an electron, it becomes negative.
Cation sort of sounds like “cat,” which is positive (Yay! Cats!).
Anions, on the other hand, sounds like “onion,” which is negative (Ew! Onions!).
There’s other ways of memorizing it, but this way was the easiest for me.

Answer:
Dear people in Westfield,
your pipes contain rust because of a chemical reaction on the iron you use.The problem could be fixed by using strong plastic pipes as that takes a long time to degrade.The rust is produced when water and air mix with the iron.it takes time for the pipe to rust but that is the problem
as I said before,try using plastic pipes that are resistant to pressure.you could get them at home Depot or other pipe production company's.
