Bleeding radiators - bleed valve is rounded

[ben5791]

Hi,

So I have read the other posts on this topic and none of the solutions have worked for me. I have a very small (once square) bleed valve located on the back right hand side of the rads.

Now I do have a bleed key, and it works on the rads downstairs. However the rads upstairs all have rounded bleed valves. The bathroom bleed valve is actually broken off!

I have tried pliers and clampy type pliers to no avail. I have no idea what to try next, sawing a line in the valve will not help as I have little to no clearance to get to the valve with a screwdriver.

Take the radiator off, try and get it out with a better gripping tool, then purchase a new bleed. Other than that it really is a new rad

Grind or file your key so it's longest in the centre. ( As though you'd sharpened it in a pencil sharpener, but 45 degrees will do.). They usually come concave, ie shortest in the centre.

You stand a much better chance then.
