made of gunmetal for drinking water protection according to DIN EN 1717
The R295 pipe separator from Resideo is a safety fitting in accordance with DIN EN 1717, developed to protect drinking water installations against backpressure, backflow and backsiphonage. It is suitable for liquid category 3 and offers low pressure loss at high flow rates thanks to its compact design and optimized flow routing – ideal for use in residential and commercial installations.

Type R295 pipe separators are crucial for protecting drinking water installations. They reliably prevent the backpressure, backflow and backsiphonage of non-drinking water into the supply network. This is not only a technical requirement, but also a legal requirement in accordance with DIN EN 1717 and DIN 1988-100 to ensure hygiene and safety in drinking water systems.
The R295 works with a spring mechanism that moves the shut-off piston to the disconnected position when the pressure drops. As a result, the connection to the drinking water network is immediately interrupted as soon as the inlet pressure falls below the defined response pressure. This design offers a high level of operational safety and reliably protects against contamination – even in the event of pipe bursts or maintenance work. For operators, this means: standard-compliant design, compact construction and minimized liability risk.
We not only supply pipe separators as individual components, but also integrate them into modular SKID systems. These preconfigured system solutions combine valves, piping, measurement and control technology into compact, ready-to-install units.
This gives you a solution that combines safety, efficiency and flexibility – ideal for projects with high hygiene and process control requirements.
