I have just drained my heating system but when I started to refill it, the header tank filled up and then stopped when the water level had reached the pre-set point for the ball valve.
The rest of the system is not refilling (probably caused by an air lock between the header tand and the circulating pump).
This may been caused by my forgetting (!) to shut all the air valves on the rads.
I have tried the following:
1. Bled all the rads.
2. Tried to blled the circulating pump (no air).
3. Shut al the lockshield valves and bled the rads (very small amount of air but no water).
Can anyone please help?
