I have a Vaillant VCW-sine 18 T3 W boiler which has been leaking for a while. My gauge shows no water pressure. The leak has been fixed, how do I refill my boiler. Unfortunately, I have no handbook for the item.

Many Thanks
Mike

Your boiler is filled via the 'filling loop' - would you believe. This is (usually) a flexible pipe connection with a tap that connects the boiler to the mains water supply- (15mm pipe). The tap may be a hand turn type or maybe a screwdriver type. Either way, your boiler is filled by turning this thing on - but careful not to overfill it as you'll have to drain it off again.
