Frequently asked questions (FAQs)
An irrigation separation station is a safety system that prevents recontamination in the drinking water pipe. It ensures the separation between the drinking water network and your irrigation system, especially when using process water or other water sources. According to DIN EN 1717, its use is mandatory when non-potable water is integrated into the water supply. This not only protects the water quality, but also the health of people who depend on the drinking water network.
DIN EN 1717 is a standard that regulates the protection of drinking water from backflow, back pressure or backflow. These regulations ensure the safety of drinking water and require the use of a system separator or a drinking water separation station when watering gardens with non-potable water. These requirements apply to all private and commercial installations and are essential to maintain drinking water quality.
There are different types of separation stations, including type BA and type CA. Type BA offers the highest protection because it allows for complete separation of drinking and non-drinking water. Type CA is often used in smaller applications and offers basic protection. Both variants meet the requirements of DIN EN 1717 and are easy to install. You can choose the appropriate type depending on the needs and size of your irrigation system.
Installing a separation station is straightforward and usually takes place between the drinking water pipe and your irrigation system. It is important that the separation station is installed in a frost-proof manner. Most models are equipped with a robust plastic or brass housing, which makes them durable and long-lasting. For safe installation, you can use the manufacturer's instructions or the assistance of a professional.
The right backflow prevention station for your needs depends on your application. For larger systems or the use of booster pumps, a type BA with a higher operating pressure is recommended. Smaller systems often get by with a type CA. Make sure that the backflow prevention station meets the requirements of DIN EN 1717 and is compatible with your pump or other components.
Backflow prevention devices are often made of robust materials such as brass, plastic or stainless steel. These materials ensure a long service life and reliable operation. Brass and stainless steel in particular are resistant to corrosion and are suitable for use in a range of applications. The choice of material depends on the requirements of your system and the water quality.
Yes, most backflow preventers are easy to maintain. Check the seals, operating pressure and functionality of the system regularly. Some models have a reset function that makes maintenance easier. You can also call in specialist personnel for a thorough check. Regular maintenance extends the lifespan of your system and ensures safe operation.
DIN EN 1717 regulates the protection of drinking water systems against backflow, back pressure and back siphonage. It ensures that drinking water remains protected against contamination by means of suitable safety precautions such as drinking water separation stations or system separators. This standard is particularly important if you use non-potable water, such as rainwater or process water, for your irrigation system. Separation stations that meet the requirements of DIN EN 1717 ensure safe operation and compliance with legal requirements. They are an indispensable component of modern drinking water installations.
Drinking water separation stations are used in many areas. They are used particularly often in garden irrigation, in pressure boosting systems or in systems with feed containers. They protect drinking water from contamination, for example, when well water or other external water sources are fed into the system. They are also required by law in public facilities such as parks or sports fields. Whether private or commercial, a separation station ensures safety and reliable drinking water protection.
Separation stations for every application – Making the right choice
Why the right separation station is crucial
Choosing the right separation station depends on several factors, including the type of water used and the size of your system. A drinking water separation station for irrigation is just as suitable for private gardens as it is for larger irrigation systems.
Steps to selecting the right product:
- Check whether you are using service water or drinking water.
- Choose a type that meets the requirements of your water supply, such as type BA for maximum safety.
- Consider materials such as brass or stainless steel to extend the service life of the separation station.
With the right separation station, you can ensure the quality of your water and meet the requirements of DIN EN 1717.
Installation and maintenance – safe operation for your system
How installation works
Installing a separation station for irrigation is easy and can be done in just a few steps. The separation station is installed between the drinking water line and the irrigation system. Make sure that the separation station does not exceed the recommended operating pressure and is installed in a frost-proof manner.
Tips for operation:
- Regularly check the function of the separation station, especially the seals.
- Pay attention to the information on the service water and drinking water installation to avoid recontamination.
- Schedule annual maintenance to ensure efficiency and safety.
A well-maintained system provides you with a reliable and safe water supply.
Separators – The key to safe garden irrigation
Why drinking water replenishment in an intermediate container is indispensable
The use of a drinking water feed into a feed tank enables protection in accordance with liquid category 5. A float valve (diaphragm spring accumulator) regulates the amount of water to be added. A centrifugal pump with a pressure switch serves as an automatic switching device for the system. As soon as water is drawn, the pump starts and delivers water. The switch-on pressure is adjustable. Overflow in the container is essential to protect your drinking water from recontamination and impurities. Particularly in garden irrigation systems that use non-potable water, a separation station ensures compliance with the requirements of DIN EN 1717. This safety component ensures that no substances such as fertilizer, dirt particles or germs can enter the drinking water network.
Advantages of a separation station:
- Effective separation of drinking and non-potable water.
- Compliance with legal requirements for drinking water installations (DVGW, DIN EN 1717).
- Reliable operation even at high operating pressures (PN10).
- Long service life thanks to high-quality materials and precise workmanship.
Isolation stations offer maximum safety and are easy to install, whether you are planning a new system or retrofitting an existing irrigation system. Automatic pump switches are prepared for direct installation with a power cable and Schuko plug.

How to install your separation station correctly
Installing a separation station for irrigation is straightforward and can be easily done by a technically minded layperson. The component is integrated between the drinking water pipe and the irrigation system to ensure a clear separation. Make sure that the separation station is installed in a frost-proof location to avoid damage in winter.
Important steps during installation:
- Choose the appropriate type of backflow prevention device according to your system requirements.
- Check the operating pressure of your system and make sure that the backflow prevention device is compatible.
- Mount the backflow prevention device vertically and make sure that the outlet remains clear to ensure safe operation.
- Connect the separation station to the water pipe and your irrigation system in accordance with the specifications of DIN EN 1717.
- Run a test to make sure that the system is leak-proof and ready for operation.
A correctly installed separation station not only ensures efficient irrigation, but also protects the quality of your drinking water.
