Flow Tests

Standpipes are installed in multi-story buildings and are available for fire hoses to connect to. Sprinkler systems are also in place in large buildings. Flow tests on these devices must be performed by a licensed fire suppression plumber.

Sprinklers and standpipes need to be tested every three to five years. Your contractor will ask the Fire Suppressions Unit of the FDNY for a specific testing date.

Your contractor will utilize this form to fax or email the FDNY Fire Suppressions Unit to request a test date. including the associated permit account number.

It costs the following to have an FDNY representative witness these tests:
