Thanks for the prompt reply B.
However, my problem is that while everybody talks of a felxible pipe, my boiler does not have one.
Under the boiler there are about 4 copper tubes and 3 silver metallic ones with black plastic caps on and nothing else.
And since all the copper tubes all look the same, as do the silver metallic ones, I have no means to differentiate which might be the filling loop.
Any suggestions anybody please?
