how do you re-charge a pressure vessal and how do you do it ,its for a Glow-worm boiler,the problem is when the heating is on the pressure is rising up to 3bars its starting point been 1bar
ok to recharge the red usually . pressure vessel with air..there is an air valve on the top of the vesssel like that on a motor car tyre .connect a motor foot pump tothe valve and add some air ..only add about 5 pounds /per square inch..shuld be sufficent.
