After draining my central heating system to repair a radiator inlet pipe. There is now air in some of the radiators. However, the air-bleed valves are rounded on 4 of my radiators! (they are the ones on the back, making it more awkward). I have tried using a new key and also wedging some paper in there, but to no avail.
1. Has anyone got a good idea?
2. Is it OK to keep the system on with air in it?
3. What about using a self-tapping screw to create an additional bleed point? Will this leak?
Thanks very much for you help in advance.
