Remove towel radiator bleed valve

[Ben B London]

Hi,

We moved into a house a couple of years ago and inherited some "interesting" plumbing throughout.

Today's problem is that the bathroom towel radiator that wasn't heating up, so I looked at it and guessed that pushing in the "button" on what appeared to be a bleed valve would bleed it. Sure enough it did. Unfortunately water then started coming out of the bleed hole and wouldn't stop, so I've had to turn off the radiator altogether to stop the leak and maintain central heating system pressure.

Maybe I'm just being thick, but I can't work out if this valve is supposed to be removeable/replaceable, and if so how I should go about removing it. I've never seen a valve like it and I can't find any markings on the radiator to research the brand, etc.

Any ideas on what I should do next? Should I just try harder to twist this off with a wrench? It's round, so the wrench teeth are going to shred the brushed finish on it but if I'm able to replace it then that's not really a problem.

Pics attached.

Regards,
Ben

Never seen one either!

I’d try prising off that round ring, I expect there might be a hex or pair of flats underneath.
Don’t go mullering it yet until you know you can replace it!

I couldn't prise it off!

Good news is that I located the manufacturer and model after some Googling around (VogueUK IN007) and got in touch with customer services to enquire about this. They sent me the following:

You can remove that push-in air vent by isolating the unit from the heating system and unscrewing the air vent anticlockwise with a set of grips. You can replace it with a standard 1/2" BSP air vent. We no longer supply those push-in air vents; we dropped them 8/9 years ago.

I'm guessing this is what I'll now try to do.

Is there anything I should specifically do / not do / be aware of when attempting this? The radiator is already turned off, so in theory I'm good to go.

I'm reasonably handy but is it worth having a plumber come out and deal with this in case something goes wrong, or is there really not much risk?

If both valves are shut off you’ll be fine.
It’ll be under a bit of pressure but you’ll only lose a little water, have pot/old towel to hand.
As it’s on the underside of that top bar I expect there’ll be some air above it anyway.

Doesn't matter here as your not keeping part but a wet rag over it should help grip without scratching up the finish.
I always add a little silicone grease to o-ring if new one has rubber seal

Thanks 🙂 You've given me the confidence to attempt the job and I've ordered up a new vent. Will report back.

We're now back to the original problem, I can't get the thing off! 😆

Now I know it's removable (in theory) I've taken my wrench to it, but just can't get enough grip/leverage. All I'm doing currently is making a mess of it (not that it matters, aside from needing to vacuum up all the shavings).

Aside from getting better/more wrenches (which I'm going to do next) is there anything else that might help me get it loose? I'm worrying that it might have corroded in place.

Thanks.

I've got a set of mole grips, which if nothing else will at least be useful again at some point, and that's helping with the grip (as you'd hope) but still not shifting.

My dad suggested heating it up, and if it was attached to exposed copper I probably would use the kitchen torch or something, but there's nothing exposed and it's too close to the (nicely finished) towel rad for me to be comfortable with that approach.

Rather than start buying tools you won’t use again, pay someone to come and remove it for you.
To get it out and replace with new vent is a £40 job.

Not sure I’m getting in my van for £40 😳

But I agree, it’s a cheap job.

Honestly, more elbow grease!

It’s not left hand thread is it ?

Turns out this was the answer. I came back to it just now after having given up last week and resigning myself to getting someone out and did manage to get it off. Replacement fitted and added some silicone grease (already had in stock from another job) as per the above.

Brownie points now earned and didn't end up spending much on getting it done either as a bonus. Many thanks for support and suggestions.
