Have you checked that the pipe going outside (pressure relief) is not dripping?. It may also be that your expansion vessel requires recharging.
Did you drain/ de-pressurise the system prior to changing diaphragm?

i de-pressurised the system (bled radiators) i cant tell if pipe is dripping outside as its lashing rain outside now, but i dont remember seeing wet on the ground earlier

Either you have a leak or the pressure relief valve is passing. That's the only way water can escape your system. Re-presurise the system and tie a plastic bag over end of pipe outside and see if it stays dry.
