What to check for Jacksonville

Some fire sprinkler lines may use double checks under specific circumstances and still sit inside the utility's annual commercial workflow.

  • Due basis: JEA runs a two-track system: commercial services are tested annually, while residential irrigation and reclaimed-water protections follow the utility checkup program. Commercial failed tests must be repaired or replaced and retested within 30 days.
  • Who is affected: JEA commercial customers, residential irrigation customers, reclaimed-water users, and certain fire-line services that require backflow protection or testing.
  • Program phone: 904-665-4410
