Hi,

Boiler related again...

Any reason a ball valve type 22mm full bore gas cock can't be located on the
external wall of the house? It could have a little enclosure put round it
if necessary?

Looked at some manufacturer data and they don't state.

My gas pipes are going to be run externally in copper, with a tee very close
to the meter box, one branch to the boiler and one branch to the cooker.

Doing the pipe size calculations suggest the pipe sizing at 22mm is
sufficient. The reason for the gas cocks is to allow easy isolation of
either branch for future convenience.

Cheers

Tim
