Hello boys - in desperation I have found this site! Really am feeling a helpless female! Can you help please? Have old indirect system (so I'm told) with a Potterton Kingfisher gas boiler. Have recently taken off a radiator and changed pipe work to fit a new type radiator so had to drain system. Now there is no hot water from the taps (they run ok but are cold) and the radiators are only half hot at the bottom. If there is a blockage or airlock is there any way I can manually put more water in the system? Any help or suggestions welcome.
