Combi Boiler Loosing Pressure

[emmawill]

Can anyone help me please?? Our combi bolier keeps loosing pressure . I topped it up yesterday to bout 1 1/2 and this morning it had gone nback to 1. I havent got a leak anywhere that i can see and i live in a masionette so have asked downstairs and they cant see any marks to suggest a leak. I Did have a problem with a rad not working in loft conversion but that seems to have fixed itself but then problem came on with pressure dropping. It never actually turns itself off as i keep an eye on it and always top it back up before it gets too low but that is every two days at min. I have asked a friend who is trainee plumber who said it may be leaking from a pipe connected thru to outside of house leaking water or i might need part changing inside boiler, any suggetsions??? He also said it may be the cold weather but i dont see how, please help me as this is driving me barmy - thankyou

yes you must have a leak somewere, check all rad valves, and the pressure relief pipe which exit,s the wall,
