Cause of low propane pressure can be caused by the valves on the top of the bottles themselves, on modern propane bottles they have now fitted safety devices which will detect leaks in your system, if your pipes or connectors have slight leaks the valve on your bottle will only let low pressure out, The remedy is to check your joints with soapy water and look for bubbles, and tighten them,then shut the valve on the top of the bottle, make sure there are no leaks, and this is IMPORTANT that the burners are turned off, then turn the bottle on again then the burner last,hopefully you'll then have full pressure again . Making sure that when you use the forge next, the burners are turned off, before you open the valve on the gas bottle.
