how does everyone else handle situations that arent strictly gas related iv just been out to an over flow from roof which turned out to be a boiler thats obviously been pumping over all though it didnt whilst i was there
its got a non return valve on the vent and push fit connnectors on the boiler, cold feed is teed in to the vent below the nrv does gas safe cover any of this?
