AVS 7

We are using an AVS 7 on our 5110. Recently, we have been having bad replicates (~6-10 % RSD), when they should be much less. It is always the 1st replicate running low. (For example, we run 1ppm checks and my first rep is 0.8 and by the 3rd/4th rep its reading 1.05 or so).  I am leaning towards the rotor seal needing replaced, but I cannot get anyone to help troubleshoot it yet. Customer service didn't have much experience with the valve. 

Anyone had this issue? Was it the rotor, or something else?
