Anti-pollution valves

Anti-contamination valve - effective protection of drinking water

The anti-contamination valve is a small element of the water installation that protects drinking water from the possibility of secondary contamination. At the Onninen wholesaler we offer a wide selection of non-return anti-contamination valves, which are perfect for both home use and service facilities and public utility buildings. We encourage you to check the offer of the best manufacturers, such as Socla, Caleffi or Watts.

Anti-contamination valve – what is its function?

What are backflow preventers for? They are fairly inconspicuous mechanical devices that are designed to protect drinking water from contamination by secondary contamination – caused by backflow. This can happen in two cases: as a result of backpressure, which has its source at the recipient (outside the water supply system) or when there is a pressure drop in the network, resulting from, for example, pipe bursts or large draws.

Regardless of the specific case, it should be remembered that the withdrawal of contaminated water poses a major threat to the entire drinking water system, and therefore to human life and health. An anti-contamination valve, if properly selected and installed, will provide effective protection against secondary water contamination.

Is a non-return valve a mandatory element of a water installation?

According to the current building regulations, a backflow preventer must be installed in the water supply system of every new building. This is indicated in the PN-EN 1712 standard, which regulates all requirements for securing the system against secondary water contamination.
