Sorry if this has been covered before, I've had a good read on here but couldnt see it's been previously covered exactly. So I need to move my gas hob and therefore additional gas supply from one side of my kitchen to the other. Currently meter is boxed externally and the 22mm copper feed comes through both outer and inner walls horizontally at about 5ft just below boiler.(see pic) The feed is teed 15mm top and bottom in the void between the inner wall and plaster board which is dot and dab. The top 15mm goes straight up to the boiler and the bottom 15mm drops down and around and off to the hob. Both 15mms are channelled into the inner wall, no plate protection. The horizontal feed from meter is sleeved and sealed meter end so any leak after that will initially spill out into the void between plaster board and inner wall, then presumably vent into the kitchen and or into the cavity which is wool filled. So to get gas to the other side of the kitchen I can:- 1. Tee off top of meter, come back out side and run around side of the house and back in again. Don't fancy that it will look *****. 2. Sweat the 22/15/15 off and replace with 22/15/22 and run the 22 down under the floor which is block and beam and screeded. Don't fancy that as it will be a ball ache to access. 3. Favoured choice; Sweat the 22/15/15 off and replace with 22/15/22 and run the 22 up into the ceiling void and along and down wall to required place. Obviously I would channel the 22mm into the wall and could protect with metal strips. I would also clip the pipe to the middle of the joist every meter. Obviously I would get a Gas Safe guy to check and sign off all works before cranking the lever. I would love to hear thoughts from any gas registered bods as to whether this is safe and acceptable. Thanks in advance.
