Would the best method be to turn the tap on the...
there is a flat head screw where the tap should be, could i unscrew that instead then tighten it once the required pressure is reached?
Edit: cheers, ill try that, thanks for all your advice. How long should the boiler be off for by i try pressurising the boiler?
I can see the filling loop, it has two connections with valve taps where it is connected to the boiler but it doesn't have the tap on the filling loop as in the image above.
