That’s not for copper.

This ones for copper but I doubt he’ll be doing the work, I wouldn’t if I just purchased it brand new.

Sorry, I just grabbed a link off Google without reading the writing on the fitting itself, good save!

Call a plumber. Deduct whatever the plumber costs from your next rent check. It's prefectly legal here and people do it all the time.

I don't really see why your messing with anything.
