Thank you for the video. In Sweden we connect top with fill and bottom with return, so we only get one air possible. Looks like the English beat us on this Plumber knowledge. Double airing is a great idea. Thank you! :)
I think it does matter what side you fit the new air release valve. If the radiator was correctly fitted, the side that the traditional vent screw is on will be a degree or so higher than the other side, thus ensuring that air is pushed out at the higher side ensuring no air pockets and subsequent cold spots.
I had a radiator in the bathroom that I was always having to bleed. I've now had this replaced with a tall towel rail. This has the same issue. I need to bleed it every week. Would an automatic air valve work on this? The bleed valve in on the top right facing up but there's a screw in plug on the other side where I presume I could put an auto valve. Also, I live in a very hard water area. Does lime scale build up in an auto valve and clog it? Thanks!
Hi do you mind me asking you questions please. Been working on House from 1850 they have a combi boiler with 2 zones replace zone valve downstairs tested heating upstairs ok downstairs nothing. Left this day and come back next day. Flushed all bottom radiators individually by disconnecting trv and adding one flex to radiator end and one flex to trv. When opened each valves good Flow coming from them. Lock shield and trv Then I put only downstairs on but no heating go through radiators they luck warm at most. When I turn other zone on downstairs completely cold. Boiler 1 years old combi Viessman 2 heating zones. Don’t have idea what to do more.
In my experience poor performance downstairs was in my case cause by scale/corosion and radiator decay. Make sure you have inhibitor in to stop scale and blockages. If that doesn't work I bet a cleaner would work to free the clogs but I'd take care with that unless you can change the entire system water because most cannot be left in. Paid for the boiler 2020 then had rads done last year but honestly I think looking back the inhibitor was what made the difference. The second plumber took the time to explain and even show me a few things. Much better experience.
@ I didn’t connected radiator to flex I only disconnected trv side and added flex to check how much flow was coming out so I have nice flow of water coming from lock shield side and trv side
@Nosilla1961 I have the exact same problem with my towel rad. In response to your question regarding the sludge (magnetite) draining the system will remove some but not all. You would need a power flush or remove them to flush water through with a hose pipe. It is a good idea to put inbitor into the system annually to prevent build up. I think All has done videos on these topics.
@@dereton33Yes! I didn't realise this until fairly recently. My understanding is that without inhibitor the water in the system reacts with the pipes and other stuff that might be floating around and over time this chemical reaction produces gases which end up making their way to the tops of the radiators. I inhibited my system after watching one of your previous videos and as yet it's doing a great job and my rads are all air free still. I can't remember how often should I put fresh inhibitor in and should I ever completely drain down the system and refill with fresh water and inhibitor?
Derek, according to Ultimate Handyman, the self bleed valves in the green packet are ‘knock offs’ and not genuine Alladin, they do not carry the 5 year guarantee. 😱 ruclips.net/video/ZoYBIllzVw0/видео.htmlsi=cqykUkgKz07wXJuC
Don`t take all he says as gospel, he is a handyman not a plumber. The valves I show came from Germany, of high quality, still working well in my radiator. They are actually better than the alladin ones.
I'd just like to say you are a true Gentleman and thank you for your help in previous videos ❤
Thanks David.

Ok,
Hi Al ,
Good idea , good to keep the manual bleed as well , I like your watch too , looking to buy a nice watch myself.
Regards,
Dermot kelly .
Ha ha, thanks Dermot.
Thanks Derek I’ve never heard of them.
No problem.
I fitted one last month and I am happy with it.
Fantastic
Good idea to keep the manual bleed valve in case you have to drain down.
Yes, true
Those Aladdins have failed on me after about 4 years of use. They just let out a slow leak when they fail. Happened on 4 out of 10 fitted.
Nothing lasts forever.
@ true but the manual air vents do a good impression! Having to replace these is not only costly but a faff.
On the Amazon link in the description above, the product claims to have a 5 year operating guarantee. Might be worth challenging.

They are normally OK.
Thanks :) what about the old single or dual raidiators?
Same for those too.
You should put affiliate links for products that you are reviewing in videos to make commissions
I do for most stuff
I'd just like to say you are a true Gentleman and thank you for your help in previous videos
I have found that even then after fitting, they still don’t get all of the air out of the system?
Top up pressure, May have been worth a mention......
Not if you have an F and E system.
Great idea. I'm always having to bleed the rads at the top of my house (2nd floor)
And that's the problem - you shouldn't have to keep bleeding the rads. With these automatic air valves you won't know.
Thats an issue. You shouldn't have to bleed radiators typically more than once a year.
That's a great idea!
Automatic boiler pressure levelling prob needed too?
They are best for F and E systems.

Flexis should not be used on heating systems to connect radiators. The system needs balancing to get heat to the downstairs rads.

I didn’t connected radiator to flex I only disconnected trv side and added flex to check how much flow was coming out so I have nice flow of water coming from lock shield side and trv side
You should have mentioned about re-pressurising the boiler. If you did this to all your radiators you may need to due to water loss.
Ok
I have same problem with towel rad at top of system constantly needing bled
What can be,causes of air in one rad?
Tx
Black sludge buid in system
Recently replaced all rads except the one getting air would draining the system not get rid of sludge?
Tx

I cant see any leaks in my system but it keeps letting air in. How fo i find where the air is coming in
It is not coming in it is being built up by lack of inhibitor in your system.
@@dereton33Yes! I didn't realise this until fairly recently.

No problem.
Could you share the eBay link ? Can't find any below £10 where I am.
Unfortunately they have gone up in price. Bought mine from Amazon. Aladdin make them.
Bought at least 6 keys.. won't catch the thread...its doing my head in
May have to be drilled out.
Bleedin’ radiators. Bleedin nuisance. 😂
Bleedin` hell.
Better to unpack the valve first so you can fit it without losing so much water
Everyone is so smart, he’s trying to help.
Thanks Liz.
Have two of these for a few years and I can tell you they don’t work.
Mine work fine.

@ 👍
It still fills up with air and you need to bleed it even with it on.
It bleeds when the heating is off.
