CS>water distiller question

[dingyung49]

Hi, group
 
   This is my first time buying water distiller.  I got it from whioe sale 
water distiller costs 248.00.  The output water has metal smell and often I 
need to wash the pot because there are lots brown color rust sittomg at bottom 
of the pot.  Does my water have comtamination due to the material of pot?  I 
dare not use this water making CS. Can I continue drinking this kind of 
water?  What is the better quality brand if mine is quesitonable?  Thanks for 
your timly advice.  Helen
