cant get radiator bleed valve to work

[ukfirestorm]

Nige after your last po I nearly asked hardware store for a pita valve key!

How would flange come off?

 

[Burnerman]

See the outer round edge, that stops your key fitting in? Its brass so easily filed away. If the square end is rounded off, mole grips will see it loose.
The complete valve assembly can be unscrewed from the rad and replaced, but that can be tricky unless you can close that rad off.

The screw bit seems too big for a key

 

[Burnerman]

Can you file away the bit of the hexagon to expose more of the squared nipple?
As I said, the complete hexagon unscrews too, but dont remove it without isolating the rad at both valves.

Will try but the actual screw seems too big,coukd the valve b elsewhere

 

[Norcon]

Drill a 3mm hole into the top of the rad and let the air bleed through that.
Then ptfe a self tapper and screw it into the hole.
Job done.

That's the bleed valve, right enough......you can actually let any air out by slackening the hexagon part - but let it pop out at your peril!

Added some more pics of same rad, I can hear water running through the bottom but it's still ice cold

What happens if hexagon pops out?

 

[Burnerman]

The rad has air in it and needs to be bled.
The bleed valve is covered in paint and that's stopping your key fitting.
Either scrape the paint off, or use some paint stripper to clean the crap away.

If the hexagon pops out, there will be water squirting out too!
