    • FREQUENTLY ASKED QUESTIONS

      - What is a hydrostatic (5 year) test?

      A hydrostatic test verifies the integrity of the system by pressurizing with water at the appropriate psi for 2 hours. The New York Fire Department issues a violation for hydrostatic testing every five years.

      - What is the difference between the 5 Year FDNY test and the obstruction investigation?

      The 5 year hydrostatic test is conducted onsite with the Fire Department to test the operations of the sprinkler system. The 5 year obstruction inspection does not require the Fire Department to be onsite, and the sprinkler system piping is inspected for possible debris that could cause pipe or sprinkler blockage.

      - What is a water flow test?

      The water flow test is conducted to ensure water flow detecting devices are operational, alarms are operational, and a signal is sent to and received by the central station (if connected).

      - What is a main drain test?

      The main drain test is performed to ensure the proper water supply is available at the system riser, detect changes in the water supply that may affect sprinkler system performance, and ensure drain valves are operational.

      - What is a backflow prevention device?

      Backflow prevention devices prevent contaminants from flowing back into the public drinking water supply. The New York City Department of Environmental Protection (DEP) requires an annual test to ensure the backflow device is operating properly.
