So your saying if you pull a vacuum on a system that's been open for a while and evaporate the water you don't have to replace the dryer?

Moisture issues aside ... if the dryer is more than a couple years old, it is not a bad idea to change it if you have had it apart.. this is because there is also a spring accumulator in it as well that can get weak over time.
