## Summary description

Sourcing SAFETY GROUP R554F is a 1-inch safety group assembly with a 3 bar pressure relief setting, combining a pressure relief valve and check valve for closed heating or hot-water systems. Designed to protect boilers and systems from overpressure, it enables automatic pressure release, backflow prevention and easy installation in domestic and light-commercial applications.

## Long description

The Sourcing SAFETY GROUP R554F 1in 3 bar — Pressure Relief and Check Valve Assembly is a compact combination unit designed for closed heating and hot-water systems. It integrates a pressure relief valve set to 3 bar with a backflow-preventing check valve, providing overpressure protection and one-way flow control in a single 1-inch assembly suitable for domestic and light-commercial installations.
Advantages
This assembly provides automatic pressure relief at a preset 3 bar level while also preventing return flow into the system. Its integrated design saves installation space and reduces the number of separate components needed. Constructed for straightforward connection to standard 1-inch pipework, the unit supports routine maintenance and reliable operation in typical heating and hot-water applications.
Suitable for
Domestic central heating systems
Small commercial hot-water and heating circuits
Closed-loop boiler systems requiring overpressure protection
Retrofit installations where a combined relief and check valve simplifies plumbing
When it may not be suitable
This unit is specified for a 3 bar relief setting and a 1-inch connection; it may not be appropriate for systems requiring a different pressure setting or non-standard pipe sizes. For large commercial systems with higher flow rates or specialized safety requirements, a larger or differently rated assembly may be necessary.
Key specifications
Connection size: 1 inch
Relief pressure setting: 3 bar
Integrated functions: pressure relief valve and check (non-return) valve
Intended application: closed heating and hot-water systems
Typical installation type: inline mounting within feed or return plumbing
How to use
Install the assembly in the system feed or return line according to local plumbing practice, ensuring the flow direction aligns with the check valve orientation. Securely tighten connections to avoid leaks and follow standard commissioning procedures for closed heating systems: pressurize, check for leaks, and verify that the relief valve opens at the correct pressure. Periodic inspection and testing are recommended to confirm continued operation and to clear any debris that might affect valve performance.
What to consider before purchase
Confirm that a 3 bar relief setting matches system design and safety requirements.
Verify compatibility with 1-inch pipework and available installation space.
Assess whether integrated relief and check functions meet local regulations for safety devices.
Usage recommendations
For reliable operation, fit the unit where it is accessible for inspection and service, follow manufacturer guidance for torque on threaded connections, and include regular system checks as part of planned maintenance. If uncertain about pressure settings or installation orientation, consult a qualified heating engineer.
