How to Re-Pressurise Your Combi Boiler: A Step-by-Step Guide by Quick Solve Property Maintenance

Signs That Your Combi Boiler Needs Re-Pressurising

Before you begin, look out for these telltale signs that your boiler may be low on pressure:

• Reduced Heating Performance: Rooms are colder than usual or the heating system is not working properly.
• Inconsistent Hot Water: You notice a lack of hot water or it becomes intermittently available.
• Pressure Gauge Reading Low: The pressure gauge on your boiler shows a reading below the normal operating range (typically between 1 and 1.5 bar).
• Warning Lights or Error Codes: Your boiler’s display might show a warning light or error code indicating low pressure.

Step-by-Step Guide to Re-Pressurising Your Combi Boiler

1. Turn Off the Boiler

• For your safety, turn off the boiler and allow it to cool before you begin.

2. Locate the Filling Loop

• The filling loop is usually a flexible pipe found beneath the boiler. It features two valves: one connected to the mains water supply and another that lets water flow into the boiler.

3. Open the Valves

• Identify the Valves: One valve connects to the mains water supply and the other to the boiler.
• Open the Mains Water Valve: Turn on the valve connected to the mains water supply to allow water to flow through the filling loop.
• Open the Boiler Valve: Gradually open the valve that leads to the boiler to let water enter the system.

4. Monitor the Pressure Gauge

• Keep an eye on the pressure gauge as you add water. Aim to bring the pressure up to the recommended level, which is typically between 1 and 1.5 bar. Always refer to your boiler’s manual for specific pressure requirements.

5. Close the Valves

• Once the pressure is at the desired level, close both the mains water valve and the boiler valve. Ensure they are tightly shut to avoid any water leakage.

6. Check for Leaks

• Examine the filling loop and connections for any signs of leakage. If you spot any leaks, tighten the connections or seek professional advice.

7. Turn the Boiler Back On

• Switch the boiler back on and allow it to operate. Check that the heating and hot water systems are functioning as expected.

8. Recheck the Pressure

• After the boiler has been running, check the pressure gauge again. It should remain stable within the recommended range. If the pressure drops again, there may be a more significant issue requiring professional help.
