Protection of Drinking Water Quality

Backflow preventers play an important role in protecting drinking water systems. They prevent contaminated water from flowing back into the drinking water network, thereby contributing to a safe and reliable water supply.

In many drinking water systems, periodic inspection of backflow preventers is a mandatory part of Legionella management. By regularly checking their operation, you can be sure that the safety measures continue to function properly.
