how do you say "spring water" in spanish?
When telling someone not to use spring water to fill a vapor machine with. How would you say spring water in Spanish?
Literally, you could say "agua de manantial". In the above context however, you have a lot of choices (unless it really is specifically spring water), such as "agua mineral" (mineral water), "agua destilada" (distilled water), etc. Hope this is of help.
Carla is totally right. Of the choices she gave you, I think "agua mineral" is the best for that context.
Agua purificada is also an option
