After replacing the DHW flow switch yesterday, I find myself waking up to a leaking auto air vent. Water has been leaking out of the vent down onto the floor.
After attempting to drain the system by shutting off the isolation valves and running the hot water taps. The air vent continued to leak.
Went in for a closer look to notice that there was a small black screw cap that had been removed from the air vent . I have replace that which has now stopped the leak. Could the solution have been that simple or is this just a temporary fix. Can't understand why this cap had beeen removed in the first place unless the guy I had round to service the boiler did so back in December.
Any suggestions would be much appreciated!
