need to drain system to replace flexy pipe and refill

what flexi pipe are we talking about
is the filler loop leaking ??????
most boiler's will have isolation valves fitted at both ends of the filler loop, look for a tap head type or a screwdriver type head that you just turn 90 degrees to isolate them .
