Horizontal runs of FlowGuard GoldŽ pipe and CorzanŽ pipe should be supported per the hanger support spacing found in Tables 1and 2. Piping should not be anchored tightly to supports, but rather secured with smooth straps or hangers that allow for movement caused by expansion and contraction. It is recommended to use full circle talon straps, which cannot pin the pipe tightly against joists or other structures. Hangers should not have rough or sharp edges, which come in contact with the pipe.
