16.4. Hydrostatic Test

Overview

NFPA 25 requires 5-year hydrostatic testing of the “piping from the fire department connection to the fire department check valve” in all standpipe and sprinkler systems, while issuing specific requirements for hydrostatic testing of certain types of standpipe systems. Specifically, all the piping in semiautomatic dry and manual wet and dry standpipe systems must be tested every five years.  

16.4.1. Scheduling

The only way to perform the test is after a Violation has been issued. Even if the Sprinkler & Standpipe Company knows that the hydrostatic test is due, one can’t be performed without the FDNY first issuing a violation. 

16.4.2. Inspection

Although the test is primarily a quality control test on the fire pumps installation and not a materials performance test, damaged materials (e.g., cracked fittings, leaky valves, bad joints, etc.) are routinely discovered during the hydrostatic test. 

16.4.3. Filing

The FDNY Inspector retains the results of the test and the building needs to retain a copy, proving compliance of the issued FDNY Violation.
