And i for one RGI wouldn't come out and test and certify your work.....because then responsibility transfers to me.......As said, DIY gas IS ilegal.....unless your competent, you are not. Think on.....you had to ask what fitting you need......bit like a pilot opening the door and asking the passengers if any of us know's where the throttle is........i wouldn't fly with him......would you???
How is competent defined by asking about a fitting?
I went to see my doctor last week, he had to use a text book to a find a suitable medicine for me. By your rules he is not either. Ridiculous.
I've successfully fitted and plumbed kitchens and bathrooms. That would give me some level competence......It's not like connecting a hob is sooooo far out of my reach because I don't know what hose to use as I've never done this particular task before. How's anyone expected to learn anything if they don't ask?
Obviously I'm going to get no help here.
