Yesterday Kyle and Gerardo noticed the current on annulus IP on GV-5 was high (off scale). Today we noticed it was at 2 mA. We tapped on the vacuum piping around the pump and the current rose. Then we opened the valve to the annulus of GV-5's gate. The current rose to 6 mA and then quickly fell to 2 mA. Closed valve again to isolate GV-5 gate annulus. Now the IP is reading 1 mA.
