Hi all,

Set off to bleed all the radiators today at home and managed all except 1. Its about a year old and iv never bled it before. A local plumber fitted it for me as part of other work.

The bleed valve goes off at aroud 30 degrees at the top right hand side towards the wall. A normal brass radiator key fits into the hole recess but then just spins and has nothing to grip. Theres just a hole in the middle square shaped? So like nothing comes up inside the key for it to turn, it just sits flush to the hole?

Is this a special key i need for this type..or is it that theres no bit of metal been put in the valve to enable the key to grip?

Sorry plumbing knowledge is poor! Thanks anyone..

Does it look anything like this in this thread??

Hey..yeah thats the one just the same as that pic?

Iv never touched it since it was installed new and that was probably 3 or 4 years ago im thinking

Get a brass key and file the end a bit thinner.

Not sure what you mean..something needs to fit into the hole in the middle of that hex nut?

There should be a bleed screw the same as all the others, if you just have a hole then the nipple has been lost and you could get wet as nothing is keeping the water in.

Ok thanks..

There is nothing protruding from the centre hole..should the key i use actually fit into that cntre hole to turn a nipple slightly inside or something?

All the other radiators have square shaped protruding bleed valves and the radiator key just sits over the top and turns easily to let the air out.

It should be exactly the same as the others, so it must have broken off if there's no square or it would leak.

If you post a pic so we can ID the rad you should be able to get a new valve.
