8:11 am (local):  valved out compressor-fed IA and valved in new N2 bottle to LVEA (2550 psig full).

8:46 am:  While bottle regulator read 82 psig, I valved out all four GV actuator pistons, after maximizing their supply pressure (all but GV7 at 78-80 psig), and then leak checked the IA line in LVEA using SNOOP. Found seven leaks and marked them with orange duct tape:

1. GV7 solenoid valve inlet (biggest leak)
2. GV7 solenoid valve outlet elbow
3. GV8 solenoid valve outlet elbow
4. GV5 solenoid valve outlet elbow
5. Cu line termination near GV8
6. inline valve upstream of GV7
7. inline valve upstream of GV5

For the morning, I've left the four GV actuators valved out to monitor bottle consumption. GV7 might start to sag because of its big leaks and limit of 60 psig. As of 10 am, there was no measureable loss at bottle, but the regulator fell from 82 psig to 71 psig.

In order to fix these leaks, we will need to close valves. Or we may end up buying a different air compressor rated for low noise.
