Fire protection system testing for commercial buildings
What gets tested, how it is done, and what the results mean — sprinkler flow tests, fire pump tests, fire alarm testing, backflow, standpipes, and more.
Measures water supply pressure at the sprinkler riser and compares it with past results to spot supply problems.
Confirms the dry-pipe valve opens properly and water reaches the system as designed.
Verifies the pump delivers its rated flow and pressure, compared with the manufacturer curve.
Every initiating device and notification appliance is tested to confirm it signals the panel and the central station.
Certified testing confirms the backflow preventer protects the public water supply and is not restricting flow.
Periodic flow tests confirm standpipes and private hydrants deliver the water firefighters will need.

FAQ
Some tests sound alarms or move water, so testing is planned with you. Alarm testing is often done after hours or in phases, and the monitoring company is notified before testing begins.
It is a test at the sprinkler riser that records static and residual water pressure. Comparing results year to year can reveal a partially closed valve or a water supply problem.
Fire pumps get periodic no-flow run tests (weekly for diesel pumps, often monthly for electric pumps under recent editions of NFPA 25) and an annual flow test.
The contractor documents the failure as a deficiency or impairment, notifies you, and quotes the repair. Impairments may require AHJ notification and fire watch.
Testing should be performed by qualified, licensed fire protection contractors. Backflow testing typically requires a certified backflow tester.
