Replacing a bleed valve is sometimes needed when the old one is leaking or damaged. This will work the same on older radiators with just the bleed screw as long as you can get the bleed screw out.

What do I do if the screw is broken? Do I just skip the step with releasing the pressure?

[@Housewarm]

Yeah, but the water will most likely squirt out fast so be prepared. Crack it slowly.

[@jadenedwin1867]

What do I do if all the water explodes out while I’m bleeding it

[@Housewarm]

Do you mean after fitting a new bleed valve?

[@pr9062]

Can you replace the nut on the opposite side at the top and what is it called?...mine are rusty and i sometimes get the odd brown dribble...thanks in advance.

[@Housewarm]

Yeah, it's called a radiator blanking plug. The bleed valve and blanking plug usually come in a pair like this one on Amazon amzn.to/3w8MSRL

@@Housewarm Thank's...is it then just a case of topping the pressure up on the boiler (combi)

[@Housewarm]

@@pr9062 Yeah, if the pressure drops to below 1 bar then top it up, but you don't typically need to unless you empty too much water out of the radiator.

[@lucipherj]

Mine have rusted around the blanking plate and a couple of the bleed valves. Do you think it would need a new radiator because of the leaks?

[@Housewarm]

@@lucipherj possibly but a lot of the time it'll fix the leak by replacing the blank or bleed valve.
It's usually leaking because the rubber o ring seal has perished, but new ones come with new rubbers.
