A former café in Gravesend, South Brooklyn shut down after repeated FDNY violations and operational issues made the business unsustainable. When new owners took over, they planned a completely different cooking concept — converting from a light café setup to a full hot kitchen with fryers, grills, and expanded cooking lines. The existing range hood fire suppression system was outdated, under-sized, and the cylinder had never been hydro tested. Master Fire Mechanical performed a full system evaluation, hydrostatic testing of the suppression cylinder, redesigned nozzle coverage for the new cooking equipment, upgraded piping, and brought the entire system into FDNY compliance. The new restaurant opened safely, passed inspection, and launched without fire system delays or violations.

Range hood fire system hydro testing in South Brooklyn Gravesend is essential when a restaurant closes, changes ownership, or opens with a new cooking concept. Older fire suppression systems often fail pressure safety, lack proper nozzle coverage, or cannot support upgraded cooking equipment. Master Fire Mechanical evaluates, hydro tests, redesigns, and certifies commercial kitchen fire systems to meet FDNY requirements so new businesses can open safely and without violations. Common reasons restaurants close or fail FDNY compliance include: Repeated FDNY fire suppression violations Expired or untested suppression cylinders Grease buildup and unsafe ventilation conditions Improper hood coverage for cooking equipment Failed inspections and compliance deadlines Unsafe electrical or gas cooking configurations Poor fire protection maintenance
