TYCO CPVC fire sprinkler piping while classified as a rigid piping material is inherently flexible. This flexibility allows piping to be deflected within permissible limits around or away from objects during installation.
The maximum allowable deflections for TYCO CPVC piping can be found in Tables N1 and N2 and Table P1 and P2.
