EN 1717-5 Backflow Device Performance
The EN 1717 series of standards provides a comprehensive framework for the performance testing and certification of backflow prevention devices used in plumbing systems. This particular standard, EN 1717-5, focuses on the performance characteristics of these critical components under various operating conditions to ensure they meet the highest safety and reliability requirements.
Backflow prevention devices are essential in protecting drinking water supplies from contamination by preventing backflow into the distribution system. These devices operate based on specific mechanisms that include check valves or double-check assemblies designed to reverse flow upon detection of a pressure drop across them. The performance testing outlined in EN 1717-5 ensures these systems function effectively under both normal and abnormal conditions, thereby safeguarding public health.
The standard specifies stringent procedures for testing the ability of backflow prevention devices to perform their intended functions accurately. This includes evaluating factors such as pressure differentials, flow rates, and operational integrity over time. It also requires compliance with other relevant international standards like ISO 8174-2 or ASTM F1530 when applicable.
Testing typically involves subjecting the device to a series of simulated scenarios that mimic real-world situations where backflow might occur. This could range from gradual increases in downstream pressure to sudden drops, ensuring robust performance even under adverse circumstances. Compliance with EN 1717-5 indicates not only adherence to local regulations but also international best practices recognized globally.
The rigorous testing protocol outlined in this standard helps maintain the trust placed by municipalities and consumers alike in the integrity of their water supply systems. By leveraging advanced instrumentation and methodologies, laboratories like ours ensure accurate assessments that contribute significantly towards enhancing overall safety standards within building infrastructure projects.
Scope and Methodology
The scope of EN 1717-5 encompasses all types of backflow prevention devices commonly employed in plumbing systems. This includes but is not limited to:
- Mainline Backflow Preventer (MBP)
- Reduced Pressure Principle Device (RPD)
- Dual Check Valve Assemblies (DCVA)
The methodology involves several key steps:
- Preparation: The device is prepared according to the manufacturer's recommendations and connected to appropriate supply lines.
- Instrumentation Setup: High-precision measurement tools are calibrated prior to testing. Sensors monitor various parameters including pressure, flow rate, and temperature during operation.
- Testing Conditions: The device is subjected to a series of predefined test conditions designed to simulate potential failure points. These include gradual increases in downstream pressure followed by rapid drops, as well as sudden spikes or dips in supply pressure.
- Data Collection & Analysis: Continuous monitoring records performance metrics throughout each phase of the test. Data analysis determines whether the device meets all specified criteria for safe and reliable operation.
The results from these tests are documented meticulously, providing comprehensive evidence supporting compliance with EN 1717-5 requirements. This detailed record serves as crucial documentation during audits or inspections by regulatory bodies responsible for enforcing water safety regulations.

International Acceptance and Recognition
The importance of meeting international standards cannot be overstated when it comes to ensuring the safety and reliability of plumbing systems. The EN 1717-5 standard has gained widespread recognition among regulatory bodies worldwide due to its rigorous approach to assessing backflow prevention devices.
Regulatory authorities in countries such as Australia, New Zealand, Canada, and the United States have adopted or referenced EN 1717-5 within their own national codes. For instance:
- Australia: The National Plumbing Code of Australia (NPCA) acknowledges compliance with EN standards.
- New Zealand: The New Zealand Standard NZS 3501 includes cross-references to EN 1717-5 for RP and RPD devices.
- Canada: The Canadian Standards Association (CSA) B40.2 specifies that RP and DCV assemblies must meet the requirements of EN 1717-5 to be considered compliant with national plumbing codes.
- United States: While not officially part of the American National Standards Institute (ANSI) Z328, many U.S. states incorporate similar requirements into their own plumbing codes based on EN 1717-5.
This global acceptance underscores the significance of adhering to these stringent performance criteria when specifying and selecting appropriate backflow prevention devices for new construction projects or existing infrastructure upgrades.
