So it is dropping very slowly. The Navac pump is good we tested it by putting the micron gauge right on the pump and got 3 microns. I called Navac this morning to ask what they think is going on. We might be pulling against a small leak - that's my concern. The decay test will be the key thing to watch.

Yes to the flares and Nylog. I had never flared copper tubing (lot of experience flaring aluminum tubing on aircraft, however), so I practiced repeatedly on scrap pieces until I was confident I was doing it correctly. This was a first project of its kind for me, but I do have many decades of tools and experience with automotive a/c, and am willing to read and follow directions, so was reasonably confident I could do the install myself, and thankfully it was successful (took me forever, though, particularly the step of routing and properly bending the copper lines through two walls, as that was definitely a first for me
).
Hopefully you/your guys will be able to find the slow leak if that is the case.
