Please confine instruction on gas work to the Combustion Chamber. I haven't deleted anything in this thread.
Maybe you didn't, we only have your word on that, but someone has.
This is a DIY forum, if posters ask question, I demand the right to answer them as A fellow DIYer.
If you are a fellow DIY'er giving dangerous advise perhaps you should do it giving the OP your full name and contact details so he and his neighbours can get in touch when things go drastically wrong. The OP was given good advise earlier in the thread and that was to contact TRANSCO. Even a RGI would have to contact them if there was a problem with either the main tap or the regulator under most circumstances.
