I have just bought a Clarke (Machine Mart) Propane Torch and found that there is a 'tap' on the regulator which appears to do nothing.
There is a tap on the Calor bottle which I can use to stop the supply and also one on the torch itself. But there is also one on the Regulator which I assumed would shut of the supply to the torch, but it does nothing.
Does anyone else have this kind of regulator? If so, does your tap do anything?
