i recently had to drain the system to change a radiator, then today
the auto air vent spurted water all over the place, good job i was at
home what a mess!
any way i got a new vent and had it fitted.
could it be related to the fact i had drained it that the air vent
failed so badly,
is it possible to fit a manual vent just for peace of mind, i dont
trust my boiler any more :(
