PRODUCT INSTALLATION GUIDE
HANDLING AND STORAGE
Exercise reasonable care in handling CPVC pipe
and fittings. Although Bow FlowGuard Gold
®
CPVC is a tough, resistant material, it does not
have the mechanical strength of metal. Cover
CPVC with a non-transparent material when
storing out-of-doors as prolonged exposure to
sunlight is not advised. If CPVC pipe is to be
installed out-of-doors, apply latex paint to it. Do
not step on, drag or drop objects onto the pipe.
PRODUCT RATING AND CAPABILITIES
DIMENSIONS
Bow FlowGuard Gold
®
CPVC is produced in
SDR 11 sizes from 1/2" to 2" with outside
diameters being CTS (Copper Tube Size). SDR
(Standard Dimensional Ratio) means the wall
thickness is proportional to the outside diameter.
This results in all diameters having the same
pressure capability.

PRESSURE RATING
Bow FlowGuard Gold
®
CPVC Pipe and Fittings
are produced to ASTM D2846 and CSA B137.6
specifications and this system has a rated
continuous working pressure of 100 psi at 180°F
(400 psi at 73°F).
FLOW VELOCITY LIMITATIONS
Traditional materials used in plumbing systems
dictate that the flow velocity of the water inside
the pipe be limited to 6 feet per second. In some
areas this has been limited to 4 feet per second.
This limit takes into account the problems of
erosion corrosion and water hammer associated
with metal pipes.
Bow FlowGuard Gold
®
, on the other hand, is not
affected by erosion corrosion and inherently
eliminates water hammer in most plumbing
systems. Consequently, Bow FlowGuard Gold
®
systems can operate with flow velocities in
excess of 10 feet per second, although 4 to 8 feet
per second velocities are recommended.
