Hello. I've got a Valliant boiler and the pressure has dropped to about point 8. I've tried turning the valve underneath the boiler and also the tap half way up the cold water pipe that goes from the floor to the boiler, to no avail. Any ideas? Thanks

Get the manual out and read it. 
Failing that, tell if you have a braided pipe under your boiler or does it need a key to refill.
Model will help.
