TM1 air to vacuum and water lines leak check at CS are finished this afternoon. The leak detector  is hooked directly to TM1 service cap so the base LR at LD is 0.0xE-9 atm.cc/sec. I sprayed helium to all air to vacuum seal on the service cap, also applied 70 psi to all water lines(except HS) for 2 minutes each. There is no any tiny response had been found on LD. So All TM1 water lines(except HS) and air to vacuum seals are leak free. The HS circuit can not be tested at this time since the VCR caps are not installed. The turbo pumps at CS and TM1 will be turned off before I leave.  See attachment pictures.
