Probably Pex. Have done my fare share of damage reviews were PEX is involved. If its left out in the sun or installed in to cold ambient temp can all lead to failure. Had on in town that had Aquatherm piping. The damage was done at installation but was not felt for 2 years. The pipe was not kept warm and when they cut it the created micro cracks in the line. They just have to read the service bulletins to know.Are they baseboard radiant or forced air/HP?
PEX or copper?
I know there is allowances for using PEX or similar to connect Reheat coils and Radiant panels, but I'm fighting that and insisting on braided connection.
