Hack Plumber? ... Oops -NO a licensed plumber!
I found this installation the hard way while installing Hardie Board on the 1st floor matser bath. This is a cantilever section below double vanity from the master bath with all four supply lines attached directly to the underside of the subfloor. I got lucky and missed the pipe twice but hit it the third time. BTW 3 years ago I had to replumb the valve and supply line for ice maker from hot to cold in the house across the street.
So it's the plumber's fault
That you're using oversized screws to anchor flooring.
Explain the how so to this; that copper piping was operating error-free until you decided NOT to measure your screws before working.
Plumbers will install piping in that fashion when the joist space is busy ie heat run, around romex runs or gas lines, beam.
Learn how to use properly sized screws next time and you won't have a reason to join a forum and complain about your stupid mistake.
Those pipes didn't leak until you screwed a screw in them, just for the record.Attachment 3323
Inciteful thread packed with knowledge!

Do you know what that means?
That means the plumber needs to allow for the most possible/largest R-factor of insulation available in this area since it is exposed to the elements when the plumbing is installed in an area where living space is non-existent.
That job (new construction) was spec'd on a 2X8 joist space with R-30 16" o.c. Kraft-Faced insulation.
See the little dabs of insulation hanging to the wood near the floor? That's why.
Plumber has to protect thier piping from bursting in an area where room temperature is not possible to protect from freezing....a liability back on the plumber,
a extreme difficulty for the insulator to properly insulate that joist space with the correct insulation to control thermal loss.
I'm right on target like I was when I typed my first response. I don't feel sorry for the event that unfolded as that plumbing was working just fine before LONG screws were shot into the floor. Don't worry about freezing, worry about long screws plumbah!
