Hydrostatic Testing
When an installation is complete and the pipe joints are fully cured, per the
requirements within this manual, the system MUST be pressure tested in
accordance with NFPA 13, NFPA 24, or any other applicable NFPA stan-
dard requirements. The system must be tested with water. The purpose of
the hydrostatic pressure test is to check for leakage, and it may not iden-
tify improperly assembled joints. This test
MUST NOT
be considered a
substitute for full compliance to our published installation instructions.
• When using Victaulic FireLock CPVC Sprinkler System Products in sys-
tems supplied by pumps, the system must be designed to ensure that
surge potentials generated by pump operation will not cause damage
to the piping system.
• DO NOT use compressed air or compressed gas for pressure testing.
• When pressure testing, the sprinkler system must be filled slowly with
water, and the air must be bled from the highest and farthest sprinklers
before test pressure is applied.
• Air must be removed from piping systems (plastic or metal) to prevent it
from being locked in the system when pressure is applied. Entrapped
air can generate excessive surge pressures that are potentially damag-
ing and life threatening, regardless of the piping materials used.
• If a leak is found, the fitting must be cut out and discarded. A new sec-
tion can be installed using couplings or a union. Unions must be used in
accessible areas only.
Painting Pipe and Fittings
The UL Listing DOES NOT cover painted CPVC fire sprinkler piping prod-
ucts. Use of certain paints, such as oil-based, can damage CPVC fire
sprinkler piping products. Before painting any CPVC fire sprinkler piping
products, you must consult with your local authority having jurisdiction for
restrictions.
DANGER
• NEVER use compressed air or compressed gas to pressure test the system.
Failure to follow this instruction could result in death, serious personal injury, and
significant property damage.
WARNING
• Air must be removed from piping systems. Entrapped air can generate excessive
surge pressures, regardless of the piping materials used.
Failure to follow this instruction could result in serious personal injury, property
damage, and/or product damage.
CAUTION
• The UL Listing does not cover painted CPVC Sprinkler System Products.
• DO NOT use harsh chemicals to clean CPVC products. Use only a mild soap and
water mixture.
Failure to follow this instruction could result in significant property damage and
product damage.
