Because we had to vent MX main volume anyway (to replace leaky turbo GV), we took the opportunity to replace IP10's iLIGO CETEC gate valve with 12" VAT gate valve. As Kyle noted in another aLOG, we started to rough out the volume so we can begin leak checking asap. We will continue pumping tomorrow and finish task by re-installing IP10. IP10 GV is closed to allow for early pump down. Will need to connect a pump cart to ion pump.
