Safety Group for Domestic Hot Water Uponor Fluvia — Uponor Grupa bezpieczeństwa (cwu) 6 bar

The Uponor Fluvia Safety Group for Domestic Hot Water is a compact assembly designed to protect hot water systems from overpressure and backflow. Rated for operation up to 6 bar, the unit integrates essential safety functions into a single module to ensure controlled pressure relief, prevent reverse flow and provide a convenient drain connection. It is designed for use with domestic and light commercial DHW installations and compatible with standard plumbing connections used in residential buildings.

Advantages

The safety group combines a pressure relief valve, a non-return valve and a drain outlet in one compact device, reducing the need for separate components and simplifying installation. Its rated 6 bar relief capacity provides reliable protection against excessive pressure, while the integrated non-return valve prevents contamination from backflow. The drain connection allows safe discharge of excess water to an appropriate outlet, facilitating maintenance and testing without system disruption.

Suitable for

• Domestic hot water systems in single-family homes and apartments
• Light commercial hot water installations
• Protection of boilers, hot water tanks and heat exchangers against overpressure
• Retrofit applications where a compact safety assembly is needed

Key specifications

• Maximum operating pressure: 6 bar
• Integrated functions: pressure relief valve, non-return valve, drain connection
• Typical installation: inline on domestic hot water supply/return lines
• Material: corrosion-resistant metals and seals suitable for potable hot water systems
• Connection type: standard plumbing fittings compatible with residential DHW piping

How to use

Install the safety group inline on the domestic hot water circuit according to local plumbing codes and manufacturer instructions, ensuring correct flow direction through the non-return valve. Connect the drain outlet to a suitable discharge point or condensate drain that complies with regulations. After installation, pressurize the system and check for leaks; verify that the relief valve activates at the specified pressure and that the non-return valve prevents backflow. Perform routine inspections and test the unit periodically to confirm proper operation and to clear any debris from the drain connection.

Usage recommendations

For reliable performance, install the safety group where it is accessible for inspection and maintenance, protect it from freezing temperatures, and use compatible fittings and sealants approved for potable hot water. Follow local regulations for pressure relief discharge routing and schedule regular checks as part of system maintenance.
