PRODUCT INSTALLATION GUIDE
Incompatible plasticizers include, but are not limited
to, phthalates, adipates, trimellitates, dibenzoates, etc.
Compatibility should be confirmed before selecting
rubber or exible vinyl materials for direct contact
with CPVC. Examples of materials which may contain
incompatible plasticizers include, but are not limited
to, caulks, rubbery hanger padding, vinyl dip coating on
metal parts, rubber gaskets, electrical wire jacketing,
electrical tape, exible hoses or tubes, etc. Further,
plasticizers may leach from rubber or exible vinyl
materials, such as hoses or tank linings, into the process
fluid which contacts them. Plasticizer contamination in
the process uid may also cause environmental stress
cracking of CPVC used elsewhere in the system. This
can include both CPVC process piping, through which the
contaminated fluid may flow, or CPVC ducting drawing
fumes from contaminated fluid. Also see section titled
“Flexible Wiring & Cable.”
Sleeving Material
• In situations where sleeving is required, the pipe should
be protected with a compatible sleeving material
extending at least 12” above and below the soil. The top
of the sleeving should be securely taped to the pipe with
a compatible tape product. Backll over underground
piping prior to termiticide spraying. Also see section
titled “Termiticides & Insecticide.”
Spray-On Coatings
• Certain types of spray-on coatings which form a
peelable lm to protect xtures during construction
may be incompatible with CPVC. Care should be used to
protect exposed piping from overspray when this type of
protective coating is applied.
Teflon
®
Tape
• Teflon
®
tape is recommended as
a preferred thread sealant.
Termiticides & Insecticides
• When performing installations underslab or where the
presence of insecticides or termiticides are likely, care
should be taken to isolate CPVC pipe from direct contact
with large quantities of these chemicals. Vinyl piping
materials such as PVC or CPVC may be damaged when
termiticides or insecticides are injected into the annular
space between the pipe wall and sleeving material
trapping the termiticide against the pipe wall. Termiticide
applications per label instructions in an open-air
environment, such as slab pretreat applications, should
not pose a problem. However, puddling of termiticides
on or near CPVC pipe may cause failures. In areas where
puddling is more likely, such as areas near tub boxes
and retreat applications, extra care should be taken to
avoid puddling of termiticides. Exercising caution and
common sense should prevent installation problems.
Before using an insecticide or termiticide, be sure to
consult the manufacturer’s installation guide for proper
application instructions. For a listing of insecticides
or termiticides that are included in the FBC System
Compatible Program, refer to FBC System Compatible
Program.
• Additional precautions need to be taken when retreat
applications are required. Termiticide retreatment is
usually required when the concrete slab has been broken
to relocate a pipe. The following recommendations
should be followed in retreat applications:
- Remove all the plastic barrier material that was
installed prior to the initial concrete pour from the
area to be retreated. Do not reinstall the plastic barrier
material
- After the pipe has been relocated, the soil should be
pretreated before it is placed in hole around the pipe. Do
not apply termiticide directly to the retreat area. Also see
section titled “Sleeving Material.
LEGAL DISCLAIMER:
The FBC™ System Compatible Program tests and monitors ancillary products to help determine whether a product is chemically
compatible with Lubrizol’s FlowGuard Gold®, BlazeMaster®, and Corzan® CPVC piping systems. Other manufacturers and/or
brands of CPVC piping have not been tested as part of the FBC™ System Compatible Program. The FBC™ System Compatible
program is, therefore, only applicable to the chemical compatibility of ancillary products with the brands of FlowGuard Gold,
BlazeMaster, and Corzan CPVC piping systems. This is because every brand of CPVC piping is made up of unique compounds, some
of which may contain resins with different molecular weights and varying chlorine content. These characteristics directly impact the
performance of the resulting product. Similarly, various CPVC products contain different performance additives. This too affects the
performance characteristics of the ancillary product. For these reasons, Lubrizol bears no liability for any failures occurring as a result
of using products in the FBC System Compatible Program with CPVC products other than FlowGuard Gold, BlazeMaster, and Corzan.
