Hi combi-doc 01214283335

I am not sure about what you mean by the pressure vessel as i am a complete novice when it comes to boilers. Could you explain exactly what i am looking for in simple terms please.

check filling loop to make sure its not open , if thats ok check pressure on pressure vessel if its below .5 bar or 10 psi repressurise with foot pump .
