Monthly HEPI Pump Pressure trends--All look Good

Attached is 40 days of trends from the first Pressure Sensor on the Pump Station.  These all look fine.  There is a drop of PS1 & PS4 when I swapped some channels around for a study.  Hmmm, I don't understand why the power outage fault seen about 2/3 through the data don't show on PS2 & 3 in the corner...?  When the EndY came back after the power outage, there is a ~2 psi shift...hmm could be that the AOFF for that channel isn't in the database.  Hey though, don't ya just love those daily and weekly glitches!?

Bottomline, none of the Pump Stations have changed there output indicating the pumps are okay.
