Is it normal for the filling loop to be fitted with two isolating valves (as below) or should it be with a flexi hose? My previous experiences of combi boilers has been the filling loop has been a flexi hose, but my recent boiler install has two isolating valves just fixed to the copper piping. Should I get these valves changed?
