Re-pressurising your boiler means that you allow more water to enter system via the filling loop. It can be easy to re-pressurise your boiler yourself. Always check your manual, but there are some simple steps you can take to restore pressure to your boiler:• Switch off your boiler and let it cool completely• Make sure both ends of your filling loop are attached• Open both valves to allow cold water into the system – you’ll hear it start to move• Look out for your pressure gauge to show 1.5 bar• Close both valves• Switch your boiler back on• Undo both ends of your filling loop and remove it. Remember some water might come out, so be ready to catch some spillage!
