yep
Thanks for your help would this be the same for a combi then just isolate on the cold supply to the boiler. No need to shut the boiler off?
You'd be better turning it off if you don't have good reason not too, but yes, it's fine to isolate the cold supply.
ok I want to leave it on because of the pilot wil this be ok if I turn the cold suplly off
