Flow Testing

---

Fire hydrants are required to be flow tested once every 5 years, as per local codes and standards. This is to ensure those system design requirements (such as minimum discharge flow and pressure) are still met at any given point across the system.  Flow testing fire hydrants is a critical aspect of ensuring the readiness and effectiveness of fire suppression systems in communities around the world. These services are essential for verifying the functionality and performance of fire hydrants, as well as assisting engineers and consultants in designing future stages of waterlines and/or sprinkler systems, ensuring that the required flows are available to provide sufficient protection to residents and property.

Flow testing fire hydrants involves assessing the flow rates and pressure levels of water systems, using 2 fire hydrants at a minimum, one being a flow hydrant and one being a residual pressure fire hydrant. This process is typically conducted by trained professionals, such as firefighters, municipal water authorities, or certified flow testing technicians, using specialized equipment and procedures. 

1. Firefighting Preparedness: Fire hydrants are critical components of firefighting infrastructure, providing firefighters with immediate access to water supplies to extinguish fires and protect lives and property. Flow testing ensures that hydrants deliver adequate water flow and pressure levels to support firefighting operations effectively.
2. Providing Information for Design:  Flow tests play a crucial role in the design process of water systems, providing engineers with essential data and insights to create efficient and reliable infrastructure. By conducting flow tests, engineers can gather valuable information about the hydraulic performance of pipes, pumps, valves, and other components within the system. This data allows them to accurately assess factors such as flow rates, pressure levels, and distribution patterns, which are fundamental to designing water systems that meet the specific requirements of their intended application. 
3. Confirming Flow Rates in Existing Systems: Flow tests serve as an invaluable method for ensuring that designed flows are met within water systems. These tests provide engineers with real-world data on flow rates, pressure levels, and distribution patterns, allowing them to validate the accuracy of their design calculations and assumptions. 
4. Regulatory Compliance: Many jurisdictions require periodic flow testing of fire hydrants to ensure compliance with regulatory standards and insurance requirements. By conducting regular flow tests and maintaining accurate records of hydrant performance, municipalities demonstrate their commitment to public safety and regulatory compliance.
5. Emergency Response Planning: Flow testing data provides valuable insights for emergency response planning and risk assessment. By identifying areas with insufficient water supply or inadequate hydrant coverage, fire departments can develop strategies to address potential vulnerabilities and optimize resource allocation during emergencies.
