Hello,
Was wondering if anyone could give me a step by step guide on how to re-pressurise my boiler and also bleed radiators? Have the gist of it but a little confused over the order for bleeding rad and topping up boiler pressure.
Have detached a rad and reattached it.
Have not at this stage opened the lockshield valve nor bled the rads.
Do I:
1. Check all nuts are tight so no leaks
2. Open lock shield valve (5 turns for me) - should i hear water filling the rad?)
3. Open bleed valve using key? (turning anti-clockwise)?
4. Run to the boiler and start to fill it with pressure using the filling key – aiming to reach 1.5 pressure reading?
5. Then run back to radiator and close the bleed valve (clockwise)?
6. Run heating then switch off
7. Re-check boiler pressure to see if pressure stayed 1.5
OR DO I:
8. Check all nuts to check tight for no leaks.
9. Open lockshield valve (5 turns)? Should I hear water filling the rad?
10. Walk to boiler and repressurise using filling key until reached 1.5?
11. Return to rad and open the bleed valve (anti-clockwise)? Listen for air coming out and look for water squirting out?
12. Lock the bleed valve once water started to squirt out?
13. Run heating then switch off
14. Re-check boiler pressurise stayed at 1.5
Also once pressure topped up are there any things that i should be looking out for just to know that I’ve done it right.
Of course will look for leaks on valves as I may not have tightened then enough.
