guinea pig not drinking

Question
I adopted a 3-4 month old guinea pig 1 1/2 weeks ago.  I took her for a check up at the vet and she is healthy.  She is being kept separate from my other 2 and every day her water bottle is still full.  

She is eating but is it possible she is getting enough water/moisture from her food?  
She is lively and active, doesn't seem to be anything wrong with her.  

Answer
did you check o make sure the water bottle is actually giving her water? I know sometimes it may look like they aren't drinking but that's because when they go to get a drink they can't get any water from the bottle. Other than that she is probably healthy. as long as she's eating normally and active i think she's fine.
