Hi all.
I'm going to have the 22mm gas pipework to the combi re-routed
as it runs through a wall in an inconvenient position.
So I think I'll need to core drill thru with 38mm diameter
cutter to make it big enough for a piece of steel
pipe to line the hole. Is that correct?

And where can I get 6" of pipe to fit in the hole ..

All proper plumbers merchants keep and sell off-cut lengths of 28mm copper
pipe
Which 22mm fits inside nicely.
