Where are these leaks coming from?

Haha you too Jay. I’ve been going through my own issues with leaks on a new build and am just now feeling like I have a grip on what all had been influencing those leaks. One is that I’m pretty sure the power jumper is leaking through the jacket because there was much less of a drop when testing both bottles together versus one bottle at a time, very repeatable. Second was that I tested with an electric vacuum pump and had much less leakage than with the hand pump, which told me that the hand pump wasn’t sealed tight, but I also think that what little leakage is left is probably from the other cable jackets in the penetrators, which is why I’m curious about backfilling them. BR also recommended the same as what k.deboer had mentioned, maybe just a few pounds so it’s not enough to blow off the end caps and either dunk it or use soapy water.
