Sprinklers must be installed only after all fittings, including sprinkler
adapters, are cemented to the piping and have been allowed to cure for
a minimum of 30 minutes. Plastic threaded plugs are available for use
during pressure testing. Before sprinklers are installed, all fittings must be
visually inspected or probed with a wooden dowel to ensure the water-
way and threaded areas do not contain excessive cement that may
restrict water flow.
CAUTION
• Use only thread sealants recommended by Victaulic. Use of any other thread sealants
may cause stress cracks in fittings for CPVC pipe. Contact Victaulic with any
questions concerning compatibility of thread sealants with Victaulic FireLock CPVC
Sprinkler System Products.
• DO NOT use a combination of paste and tape on threaded connections.
• DO NOT over-torque threaded connections.
• DO NOT use tools with teeth on any part of a CPVC fitting. Tools with teeth can
damage and weaken CPVC material.
Failure to follow these instructions could cause product damage and joint leakage,
resulting in property damage.
