Here is a 45-day trend of HEPI Pump Pressures & Drives (thus closing out FAMIS # 4517).

A few note:

• EX Pressure & Voltage drive, made slight shift down on Jan 5th (and the noise levels became quieter)
• EY Pressure & Voltage drive had shifts on 1/21 & 1/27;  in between these dates the noise levels were noisier than before and after.
