Fire Hydrant Testing & Flow Requirements: Complete NFPA 291

What is the best fire hydrant test?

The most effective and compliant fire hydrant testing strictly follows NFPA 291 standards. This nationally recognized protocol evaluates available water supply by measuring static, residual, and flow pressures. A proper NFPA 291 flow test, which is a critical part of fire hydrant inspection and maintenance, ensures hydrants can maintain a safe minimum of 20 psi (1.4 bar) residual pressure during firefighting operations. This provides fire departments with accurate capacity data before an emergency occurs.
