Water line pressure test

So I winterized the coach via the air method and I noticed that the lines would slowly bleed down from 30psi. Shouldn't they hold the pressure? Doesn't this mean there is a leak somewhere? It didn't drop right away, or quickly, but it was dropping pressure around a psi every few minutes.

Air pressure will leak down a lot faster than water pressure
If you are afraid to speak the truth out of fear of what others may think, it says a lot about who you are and what you will settle for.
