Stop being a muppet and take it into the forum it should be discussed in...the CC,
If you are a registered gas engineer you'll have no issue with joining and would surely agree that discussing gas critical safety parts should not be for a public forum....
Your lack of even basic testing and gas valve knowledge is a worry but fine, i will give you the benifit of the doubt......join the CC and you'll get your question answered.....otherwise your either an illegal gas worker or are a joe public trying to save money....
