A hydrostatic pressure test is an examination that affirms the good working condition of a fire protection system (sprinklers). The New York City Fire Code section 903.5 states that fire department sprinkler connections must be tested and witnessed by a fire department representative at least once every 5 years. The test can only be performed by a fire suppression contractor who has a Class A or B license issued by the NYC Department of Buildings (DOB).

What is a hydrostatic pressure test?

Five-year hydrostatic pressure tests are lifesaving procedures. These tests simulate fire department activities that take place during an actual fire. A hydrostatic pressure test basically is a confirmation that the tested sprinkler system will perform as designed and will function adequately for at least two hours under the highest water pressure that the system is likely to experience.

When freezing conditions prevail, the hydrostatic test may be postponed, provided a dry pressure test (using air or nitrogen) is performed in the interim. The dry test must be witnessed by a DOB inspector or special inspector, as does the hydrostatic test. If the hydrostatic test is deferred due to freezing temperatures, the hydrostatic test must be performed when freezing temperatures no longer exist.
