This is why you have to force people to take pics of their work and good QC.
Went to set a 5ton on a 2 system house (5/2) Saw that both coppers were 3/4.
Went to investigate.
Found 7/8 at furnace. Trace the lineset back.
Found a barely taped spot and cut open. Damn they spliced it with 3/4.
Called out rough lead who originally did the work. Wasn't him, apparently the copper was stolen at some point and was reran by worker we had doing misc jobs. Of course he has done quit.
We used to have good QC who would force you to take pics and go back and take pics if you forgot. But that is long gone. Especially if they have only been at the company a couple of months.
