Streamlined Hydrostatic Testing with Digital Documentation

Hydrostatic testing is a critical part of maintaining code-compliant fire extinguisher equipment in New York. NFPA 10 standards require that all pressurized fire extinguisher cylinders undergo hydrostatic pressure testing at specific intervals to verify their structural integrity. A&J Fire Extinguisher Corp performs this testing at our Brooklyn facility for commercial and residential clients across all five NYC boroughs, Long Island, and New Jersey.

During a hydrostatic test, each cylinder undergoes a thorough external examination first to check for visible damage. The cylinder is then filled with water and then pressurized to a level higher than its normal operating pressure. This is the water jacket method used to ensure that your fire extinguisher can still withstand its pressure rating. The process checks for corrosion, abrasion, dents, and weld damage that could cause the cylinder to fail during use. Testing evaluates the extinguisher's critical components, including the shell, neck, and threads, to confirm they can safely hold pressure. Our FDNY-certified technicians follow DOT-compliant procedures and provide digital documentation with every test, so you have the records you need for audits and FDNY inspections.

NFPA 10 Hydrostatic Testing Intervals

NFPA 10 sets specific testing intervals based on extinguisher type. Property owners must also perform monthly visual inspections every 30 days to check for obvious damage, low pressure gauge readings, or missing seals. The full hydrostatic testing schedule is as follows:

  • Dry Chemical (stored pressure and cartridge-operated) - hydrostatic test every 12 years, with an internal inspection at 6 years
  • Carbon Dioxide (CO2) - hydrostatic test every 5 years
  • Clean Agent (Halotron, FE-36, Halon) - hydrostatic test every 12 years
  • Dry Powder (Class D) - hydrostatic test every 12 years
  • Water, foam, and wet chemical - hydrostatic test every 5 years

Standard portable extinguisher testing typically costs $25 to $75 per unit, depending on type and size. CO2 and special hazard units may cost more. A&J Fire offers free estimates and volume discounts for multi-unit testing.

Dry Chemical Extinguisher Testing

ABC dry chemical extinguishers require hydrostatic testing every 12 years, with an internal inspection at the 6-year mark. Our testing process includes a full visual examination of the cylinder exterior, removal and inspection of internal components, and a pressure test to confirm the cylinder can safely hold its rated pressure. After passing the test, we reassemble the unit, recharge it to factory specifications, and apply a new inspection tag.

If your dry chemical extinguisher needs recharging before or after testing, our recharge and refill service restores it to full operating condition.

CO2 Extinguisher Testing

CO2 fire extinguishers require hydrostatic testing every 5 years due to the high pressure at which they operate. Our technicians perform DOT-compliant pressure testing on CO2 cylinders to verify they can safely contain pressurized carbon dioxide. CO2 extinguishers are commonly found in commercial kitchens, server rooms, and electrical equipment areas. We also service commercial fire extinguisher accounts with scheduled CO2 testing programs.

Water-Based Extinguisher Testing

Water, foam, and wet chemical extinguishers typically need hydrostatic testing every 5 years. These extinguishers are tested by filling the cylinder with water and applying pressure to check for leaks or structural weaknesses. Our team handles all water-based cylinder types including pressurized water, AFFF foam, and wet chemical Class K units used in restaurant kitchens.

Cylinder Inspection and Disposal

Before any hydrostatic test, we perform a thorough visual inspection of each cylinder. If a cylinder shows signs of damage that would cause it to fail, we document the findings and recommend removal from service. When an extinguisher fails testing or is condemned, we handle safe disposal and recycling in accordance with environmental regulations. We also provide replacement units at competitive rates so your business never has a gap in fire protection. The entire process is hassle-free for you and your team.

If your building has received an FDNY violation related to expired or untested extinguishers, our violation removal service resolves it quickly, often the same day.
