a=auto,a=air, v=vent pretty basic stuff automaticly lets the air vent to atmossphere the cap needs to be loose to let the air out letting water out means the aav needs replacing as it is not doing its job,screwing the cap down will stop the water but leave the air in the boiler so you have another problem and so on and so forth,get the boiler serviced and the aav changed before you create more probs

the auto air valve works in the same way as an old type snorkel, a water vessel with a hole in the top and a float inside. when air enters the chamber, the float drops opening the top hole, as air escapes water level rises lifting the float reseals the hole.
when these start leaking replacement is the only solution.

There is a few reasons why your pressure could be dropping
If the boiler is still working when it is on 1 bar then keep it there when i fit a bolier i would normaily put 1 to 1.5 bar of pressure in the system the pressure value will kick in if the pressure get to 3 bar and the normal working pressure is 1 bar for most combi boilers read the manual before taken action to see what the pressure should be on.
if it will not work on 1 bar and the manual says it should be higher tell me and i will give you some other reasons why this is happened
I bet they thought the three wait was worth it for your input chaz
