What is the 5-Year Hydrostatic Test

The FDNY requires this test to ensure your FDC (Fire Department Connection) can withstand high-pressure water flow during emergencies. Over time, rust, leaks, or weak fittings can compromise your system. The test simulates FDNY pumper truck pressure to confirm your FDC’s reliability.
