Flood is a natural phenomenon, usually caused by heavy rain, river flooding, and other reasons.

Floods can cause overloading of the drainage system and may even cause wastewater to flow back into the water supply system.

The design purpose of the built-in anti backflow device in the pipe is to prevent water flow from flowing backwards,

With a return water protection function of up to DN 1800, it can prevent water flow backflow.

It can prevent the phenomenon of drainage outlet backflow caused by water level rise. Thus reducing the load on the water supply system.

High water level refers to the elevation of the water level in the water body, in which case the water body may backflow into the pipeline system, causing the system to be submerged.

In this case, using a built-in anti backflow device in the pipe can prevent backflow caused by high water levels in advance,

To avoid or reduce the risk of pipeline flooding and protect infrastructure from damage.

The built-in anti backflow device in the pipe can be used in various ways in the pump station.

The design of the built-in anti backflow device in the pipe is flexible and can adapt to different pipeline systems and requirements.

For example, it can be installed upstream or downstream of the pump station to prevent reverse fluid flow.

In the animal kingdom, rodents, insects, and other pests may cause various damages and diseases to water and sewage systems.

For example, rodents may bite through pipes, while insects and other pests may breed in the pipes,

This may lead to blockage or contamination. The built-in anti backflow device in the pipe can prevent them from entering the water supply and sewage system.

Flooding in basements is usually caused by rainfall or the influx of other water sources. The built-in anti backflow device in the pipe can be an ideal solution to solve the odor problem in sewage systems. Its unique design can prevent the spread of odors in the sewage system, thereby reducing the impact on the surrounding environment and air.
