    4. Install the new gauge
      Screw the new pressure gauge into the fitting by hand, then tighten it gently with the wrench. Avoid over-tightening, as this can damage the gauge.

    5. Restore water supply
      Turn the water supply back on and check for leaks around the new gauge.

    6. Power up the boiler
      Reconnect the power supply and monitor the gauge as the system heats up. Ensure it stabilizes within the normal operating range.

    Post-Replacement Pressure Gauge Monitoring

    After replacing the pressure gauge on your Vaillant boiler, it’s crucial to monitor its performance to ensure optimal functionality. Regular checks can help identify any potential issues early, maintaining the efficiency of your heating system. Understanding how to interpret the readings will empower you to take timely action when necessary.

    After replacing the pressure gauge, monitor the system closely. If the gauge does not show the correct pressure, additional troubleshooting may be necessary.

    • Check for leaks around the new gauge.

    • Inspect the boiler for any signs of water loss.

    • Verify that the expansion vessel is functioning properly.
