bleeding a radiator

Mrsmoneypenny

I am trying to bleed a radiator, I have done all the radiators in the house but one is being a problem.

The valve is between the radiator and the wall at the top of the radiator.

The problem is that the thread has been worn away, the key does catch in one place but there isnt enough thread left to get a good grip.

The radiator is lovely and warm at the bottom and it stone cold at the top, so I think if there is a way of bleeding it without the key it should be fine.

Thanks in advance.

Not really possible, the bleed valve will need replacing, not a very big job.

The bleed nipple will be in a fitting that can be changed without draining the system, if you know what you are doing.

Close both valves on the radiator then unscrew the fitting, wrap some PTFE tape arround the thread on the new fitting and refit.

BUT ONLY IF YOU FEEL CONFIDENT ENOUGH.

I once did this.....
Put the small finger part of an empty rubber glove (or use a similar material) over the key then insert covered key into the valve and turn - should work !!

you can also use one of those very small sockets hammered over the bleed valve. then use a normal socket key to operate.
