i asked the question why my pressure keeps dropping ,i have checked all pipes valves as u suggest ,there seems to be no leaks.the pipe that goes outside is dry.any idea?
thanks
you might find that the pressure vessel needs recharging with air the press is probably rising to quickly the pressure relief vents then dries no sign of any leak but pressure loss

Check inside the burner area, leaks are fairly common on the main heat exchanger, but are not evident externally for quite some time.

have you checked all pipes under floor? have you any pipes in concrete floors? some leaks can be a pain to find it doesn't take much for pressure to drop. how long does it take to drop?
nothing leaking inside boiler?
