Burnaby Backflow Testing and Prevention Services by DJ Plumbing
All backflow testing must be performed by a licensed company with technicians who hold a cross-connection certification.
Most people assume that water only flows one way—from the source to the tap. However, under certain conditions, water can flow in reverse. This can happen when a water main breaks, a pump fails, or a heating/cooling system builds up too much pressure. Backflow can be caused by back pressure, which occurs when the pressure in the system exceeds the supply pressure, or by back siphonage, which happens when negative pressure in the water line draws water backward. Backflow systems are essential for protecting pipes and ensuring the safety of the water distribution system in all types of properties, including those with sprinkler systems.
When backflow occurs, even briefly, it can contaminate the fresh water supply with non-potable water. This creates serious health risks, including exposure to waterborne diseases such as E. coli, Salmonella, and Giardia, as well as toxic chemicals like pesticides, metals, and volatile organic compounds. Backflow can affect both residential and industrial environments. Backflow issues can arise in both residential and commercial properties, and property managers should be vigilant to ensure water safety and compliance.
Contamination from Cross Connections
Equipment failure isn’t the only backflow risk. A cross connection occurs when a potable water system is directly or indirectly connected to another liquid, gas, or solid. Without proper backflow protection, this can cause contamination. Backflow prevention assemblies and backflow prevention devices are required to protect the water distribution system from contamination, especially in systems with fire sprinkler systems, irrigation, and drains. Proper installation of a backflow assembly (backflow assembly installed) is necessary for compliance and safety.
For example, older commercial fire suppression systems often contain water that has been stagnant for years in black iron piping. Without backflow devices, contaminants such as lead can enter the drinking water supply. This makes backflow prevention crucial for protecting public health.
How Often Do Backflow Prevention Devices Need Testing?
The City of Burnaby requires annual testing of all backflow prevention devices. If a device fails testing, the property owner must repair the equipment and then have it retested to confirm compliance. Backflow prevention assemblies must be tested regularly, and a test report is required for compliance.
Backflow prevention devices must also be tested when they are installed, repaired, relocated, or replaced. To ensure they function correctly, inspections and installations must be carried out by a certified tester. After each backflow testing service, a test report must be filed with the city, and the cost may vary depending on the type of property and whether a test report is filed.

Introduction to Backflow Prevention
Backflow prevention is a vital component of any plumbing system, ensuring that the water supply remains clean and safe for everyday use. Backflow occurs when water flows in the opposite direction from its intended path, which can allow contaminated water to enter the potable water system. This reversal can happen due to changes in pressure, such as during a water main break or when there is a sudden drop in the municipal supply. To combat this risk, backflow prevention devices—including backflow preventers and backflow assemblies—are installed to guarantee that water only flows in one direction. In Burnaby, BC, annual backflow testing is required to confirm that these devices are working properly and effectively preventing contamination. Certified backflow testers play a crucial role in this process, performing regular backflow testing and repairs to protect public health and maintain the integrity of the water supply. By prioritizing backflow prevention, property owners can significantly reduce the risk of contaminated water entering their plumbing systems.
What is Backflow Assembly Testing?
Backflow assembly testing is a specialized process designed to ensure that backflow prevention devices are operating as intended. During this procedure, certified technicians carefully inspect and test each backflow assembly to verify that it is effectively blocking contaminated water from flowing back into the drinking water supply. Using advanced equipment, technicians simulate backflow conditions and monitor the device’s response, checking for any signs of malfunction or failure. In Burnaby, BC, this testing is not only recommended but required on an annual basis, with test reports submitted to the city to demonstrate compliance. Reliable backflow testing services help property owners and managers maintain a safe water system, prevent contamination, and meet all regulatory requirements. By having backflow assembly testing performed regularly, you can ensure your property’s water supply remains clean and safe for everyone.
Backflow Test Procedures
The process of backflow testing involves a series of detailed steps to confirm that backflow prevention devices are functioning correctly. Certified technicians begin by thoroughly inspecting the device for any visible issues or signs of wear. They then conduct a differential pressure test and a flow test to assess whether the device is effectively preventing backflow. If the backflow preventer fails any part of the test, necessary repairs or even a full replacement may be required to restore proper function. Backflow repair can range from replacing worn seals or valves to installing a new device if the existing one cannot be fixed. Regular backflow testing, including annual testing, is essential for identifying potential problems early, reducing the risk of contamination, and protecting the health of building occupants. By ensuring your backflow prevention devices are tested and maintained by certified technicians, you help safeguard your property and the broader community.
Backflow System Maintenance
Maintaining your backflow system is key to ensuring the ongoing safety and reliability of your water supply. Regular maintenance, including annual backflow testing, allows property owners to catch and address issues before they escalate into costly or hazardous problems. Backflow preventers and backflow assemblies should be inspected and tested regularly by certified technicians to confirm they are operating as designed. Maintenance tasks may include cleaning, lubricating, or replacing worn components such as check valves or seals. By scheduling routine backflow system maintenance, property owners and managers can prevent contamination, avoid emergency repairs, and ensure compliance with local regulations. Prioritizing the upkeep of your backflow system is an investment in the health and safety of your property and everyone who relies on its water supply.
Backflow Preventer Installation
Proper installation of a backflow preventer is a critical step in protecting your property’s water supply from contamination. Backflow preventers and backflow assemblies are engineered to stop contaminated water from flowing backward into the potable water system, especially during pressure changes or plumbing emergencies. When installing a backflow preventer, it’s important to select a device that meets local codes and is appropriate for your specific plumbing system. Certified technicians can guide you through the selection process and ensure the device is installed correctly for optimal performance. Professional installation not only helps prevent backflow but also ensures your property remains in compliance with Burnaby’s regulations. By investing in the right backflow preventer and having it installed by experienced professionals, you are taking a proactive step to protect your water supply, maintain system integrity, and safeguard public health.
