Hi i am about to do some work on my house and im having a new boiler fitted.
My old boiler has a 15mm gas pipe going to it and the new boiler is 22mm gas pipe. Can you just solder in a 15mm to 22mm pipe adapter. i know this is for a gas safe person and yes i will be using one but, i would like to know how he would go about it.
The main feed pipe from my meter is slightly bigger than 22mm. it goes under the floor in the house and splits, one for the hob and one for the boiler and comes out the floor as 15mm.
Regards
Pat
