Brixing FBD 564 and what causes bad brix 

Thanks so much! Very good video

Two questions. Can you make a video on how to flush out the lines? Also for someone that isnt in a commercial setting(if it matters) since the brix changes on an expired product, can you still use the expired product if you adjust the brix concentration to reach the 14%?

I got a lot of questions i buy 2 fbd 564 used machines its a way to contact u by phone
