ok point taken , massage to all d i y people do not mess with gas in uk you will blow up your selves and everybody in the street
in fact i had a plumber call out who told me that he did not solder , and he actually works as a plumber for the local council over her, they compression fit everything
the local izi stores ,thats b q eqivelent here sells a full range of flexible gas pipe and compression fittings,yes bright yellow and used every day by lpg gas installers and any diy guy
also they connect flexi hoses direct in to boiling hot water boilers hence all the abuse and rubbish i had to take off certain posters on this forum when i asked if it is acceptable to do so,< no its not allowed in uk to do so>
cheers
