I have a 22mm gas pipe going from my meter in the garage to my boiler in the kitchen. It has a 15mm t off the 22mm for a gas cooker. There is 8.5m of 22mm plus 6 90 degree bends, easily accessible in the garage, and 5m in the kitchen that will be difficult to access. If i change the 22mm in the garage to 28mm, and join this to the 22mm as it enters the kitchen, will this improve the capability of the gas service. I realise that a calculation is necessary, but will what i am suggesting actually work.
