Maintenance
Maintenance shall be in accordance with the Standard for Inspection, Testing, and Maintenance of Water Based Sprinkler Systems as defined by NFPA 25.

Limitations

  • CPVC systems are intended for use at a maximum working pressure of 175 psi and ambient temperature of 150°F.
  • CPVC systems shall employ sprinkler heads having a maximum temperature rating of 225°F or lower, regardless of type.
  • CPVC products shall be installed in wet pipe systems only.
  • Air or compressed gas shall never be used for pressure testing.
  • CPVC sprinkler systems shall be hydrostatically tested for 2 hours at 200 psi, or 50 psi in excess of the maximum working pressure when the maximum working pressure exceeds 150 psi. Lines shall be slowly filled with water and the air bled from the highest and farthest sprinkler heads before test pressure is applied.
  • Only Teflon® tape or a thread sealant specifically approved for use with GF Harvel® CPVC Fire Sprinkler Products shall be used in making threaded connections.
  • Where freeze protection is required, only glycerin based anti-freeze solutions shall be used and installed in accordance with NFPA 13. Do not use glycol base anti-freeze solutions or contaminated glycerin solutions.
  • CPVC is not approved for use in combustible concealed spaces where sprinklers are required to protect these areas as defined by NFPA 13, unless certain specific application sprinklers are installed per their listing. Refer to GF Harvel's current Installation Instructions for additional information.
  • CPVC sprinkler piping may be installed in a plenum space adjacent to, but not over, openings in the ceiling such as open ventilation grills, and require the use of schedule 80 fittings for use on 1 _" and larger pipe sizes. Refer to Installation Instructions for additional detail.
  • Minimum protection when installed "concealed" shall consist of: 3/8" gypsum wallboard or drywall, suspended membrane ceiling panels weighing not less than .35 pounds per square foot, or 1/2" plywood soffits. Minimum protection for NFPA 13R and 13D systems may consist of 1/2" plywood.
