• After the joint has properly cured, inspect the line for proper alignment
and hanger placement before pressure testing.
• Whenever possible, Victaulic recommends isolating the portion of the
sprinkler system that contains the cut-in tee before pressure testing. The
applied test pressure MUST NOT exceed 50 psi over the system pres-
sure in order to minimize water damage in the event that leakage
occurs.
• To pressure test the system, slowly fill the system with water. Make sure
all air is bled from the furthest and highest point before test pressure is
applied. The system MUST be pressure tested in accordance with NFPA
13, NFPA 24, or any other applicable NFPA standard. The system must
be tested with water. The purpose of the hydrostatic pressure test is to
check for leakage; this test may not identify improperly assembled
joints. This test MUST NOT be considered a substitute for full compli-
ance with the installation instructions published in this manual.

Note 1
‡ Solvent cement, pipe, and fittings brought in from colder temperatures must be allowed to
reach at least 60°F before using these cure times.
Note 1:
Solvent cement can be applied at temperatures below 40°F for all sizes. For the
2-inch size, the temperature must be raised to 40°F or above and must be allowed to cure per
the required times listed in this table before the system is filled and pressurized.
WARNING
• Victaulic FireLock CPVC Sprinkler System Products must never be used or tested in
a system that contains compressed air or other gases.
• Air must be removed from piping systems. Entrapped air can generate excessive
surge pressures.
Failure to follow these instructions could cause product failure, resulting in serious
personal injury and/or property damage.
