TM3 has had all of the water lines pressurized with Helium and the Helium Leak detector was connected to the turbo pumps. There were no leaks detected.

 While pressurizing the lines it was found some of the lines had water in them. It is unknown where this water came from. Perhaps David connected the conditioning station last time it was in? Lines that were free of water were A, B, C, and window The leak detector pumped down to 4.0 x 10^-3 Torr and the leak rate was 1.4 x 10^-9 atm-cc/sec, there was no response during the leak test and the leak rate continued to decrease during the test.
