Vacuum Group applied a temporary fix to the lower body seal on IOS:TP7, which we found last night to be leaking. Edi tells me that similar seals have failed before. It's an O-ring, not a metal seal. The fix now was to marinate the outside seam with silicon grease and wrap with Teflon tape. We'll see how that improves the backing line after a while.

Meanwhile, Vacuum Group is setting up to leack check the work.
