Fire Sprinkler Testing in Oklahoma City, OK
Fire sprinkler testing is the physical, functional verification that your sprinkler system's water supply, alarms, and control valves perform as designed. While inspection is the visual examination, testing physically exercises the system — running main drain tests, triggering waterflow alarms, and verifying pressure. Oklahoma City Fire Protection performs NFPA 25 sprinkler testing for commercial properties across the OKC metro.

Understanding fire sprinkler testing
Sprinkler testing physically exercises the system: main drain tests verify water supply adequacy, waterflow alarm tests confirm the alarm activates when water flows, and control valve tests verify proper operation.
NFPA 25 defines specific test intervals and methods. Annual main drain tests and waterflow alarm tests are required, with additional tests at 5-year intervals for internal piping and sprinkler head samples.
We test and document — we do not repair. Deficiencies found during testing are reported for your licensed sprinkler contractor to correct.
