Different/Non standard Bleed Valve

meenmara

Hi

Can anyone help - I need to bleed my radiators but they dont have a standard bleed valve. They look like old radiators. I recently bought the house and this is the first time I have had to bleed them.

The nut is 1cm in diameter and is not the standard type where you insert a specific bleed key and turn it. This looks like you need to insert something pointy to release the air. I have a picture but I dont seem to have the option to upload it here.

If anyone can help Id really appreciate it.

Thanks

are you sure its not just missing the usual bleed screw and they are just after closing the valves on both sides of the rads so leave the rad dead essentially ?? I have worked on systems installed 50 years ago and they had the standard bleed screw.

I would assume that if the valve was closed then the radiator would not work?? All of the radiators that have these screws work, its just that the heat in some of them is only coming a third of the way up the rad...hence why I want to bleed them. I think I have attached a picture of the screw.

The house is about 25 yrs old and I suspect that the rads were there originally as there is one newer rad in another part of the house where renovations were done.

Thanks for reply.

are you sure you dont just loosen the nut and thats the bleed screw?
