Check
Look for a raised or misnested gore segment.
Check if the elbow angle shifted during install.
Reset the gore into its track before sealing.
Fasten the seam after the fitting holds shape.
Seal the corrected seam per pressure class/shop standard.

Say this to your foreman
The adjustable 45 at [location] is leaking because one gore segment is not seated in its track. I can reset and fasten it, or replace it if the seam is damaged. Which do you want?
