Range Hood Fire System Hydro Testing Gravesend Brooklyn
When restaurants change ownership or concept, compliant fire system redesign and hydro testing are critical.




- Why is hydro testing required when reopening a restaurant? Hydro testing ensures the fire suppression cylinder is safe, properly pressurized, and capable of protecting the new cooking setup.
- Do new owners need to redesign the fire suppression system? If the cooking equipment or kitchen layout changes, the fire system must be redesigned for proper coverage and FDNY compliance.
- What happens if the old system is not compliant? Non-compliant systems must be upgraded or replaced before the restaurant can legally operate.
- Can a restaurant reopen with an old suppression system? Only if the system passes inspection, hydro testing, and meets current FDNY requirements.
- How does hydro testing help avoid future violations? It confirms cylinder safety, pressure stability, and system reliability, reducing the risk of failed inspections and shutdowns.
| System Component | Test Requirement | Frequency | Risk if Not Tested |
|---|---|---|---|
| Suppression Cylinder | Hydrostatic Pressure Test | Every 12 Years | Cylinder rupture or failure during fire |
| Discharge Lines | Pressure Integrity Check | During Hydro Test Cycle | Agent delivery failure |
| Nozzles | Flow Verification | System Service Interval | Improper fire suppression coverage |
| Control Head | Mechanical & Pressure Check | Annual Inspection | System activation failure |
| Agent Tank Integrity | Structural Safety Test | Hydro Cycle | Unsafe discharge or system malfunction |
