in the pic, I can see where someone (piker) screwed the fittings in too tight and the line was wracked to begin with. I'd rip the whole assembly from the valve to wherever you can get clean meat; class 200 does not help.
Slip 45's, (pre-aligned with a felt marker) should get you clean and tight. I'd replace the sch 80 union as well, and make sure it was Spears or Lasco. Order a set of "O" rings for the client, and after the bill is paid, he'll be a happy camper, as we say on the road. If you know what you're doing, unions may not be needed.
