Can bacteria grow in PEX pipe?
PEX pipe showed a higher growth of coliform bacteria than copper pipe [42]. The levels of released metal from plastic pipes were monitored in five pipe systems, PB, PVC, PP, PE, and cPVC. The metal levels in new plastic facilities were not serious except for PVC and cPVC, respectively.
