I need to re-pressurize my boiler only it shut off last night due to the dropping below the lower limit on the dial, after reading all the bumff I have realized I need to open the water supply to the boiler, it looks like I need a screwdriver? I have had a good look around the home and there is no key anywhere? I can use a screwdriver but I am concerned in case the water rushes in and does any damage? any suggestions ... my gas fitter is on holiday at the moment!.
