Check valves
The anti-pollution check valve is a protective plumbing device capable of preventing the backflow of polluted water into the mains system. This may occur due to changes in pressure in the distribution network that cause water to flow backwards. The check valve, which is fitted between the main water system and the user system in water distribution solutions, prevents any contact between the water in the two systems, as it closes automatically whenever backflow conditions occur.
