Tilbageløbssikring

Tilbageløbssikring, often translated as backflow prevention, refers to measures and devices designed to prevent contaminated water from entering the potable water supply system. This contamination can occur when there is a sudden drop in pressure within the supply system, causing water to flow backward from a lower-pressure source into the higher-pressure potable water lines. This phenomenon is known as backsiphonage or backpressure.

Backflow can introduce harmful substances such as pollutants, chemicals, or bacteria from sources like irrigation systems, industrial processes, or even domestic plumbing fixtures into the drinking water. To mitigate this risk, various types of backflow prevention devices are employed. Common examples include vacuum breakers, pressure vacuum breakers, reduced pressure zone assemblies, and double check valve assemblies. The choice of device depends on the specific application and the degree of hazard posed by the potential backflow.

Regulations and codes in many jurisdictions mandate the installation and regular testing of backflow prevention devices in certain settings, particularly where there is a higher risk of contamination. This includes commercial buildings, industrial facilities, and even some residential properties with specific plumbing configurations. Regular maintenance and testing are crucial to ensure that these devices function correctly and continue to protect the public water supply from contamination. The primary goal of tilbageløbssikring is to safeguard public health by maintaining the integrity of the clean water distribution network.
