Can't thank you enough. Superb clear instructive video. Flow and return pipes both cold on one radiator - followed your instructions - opened up lock-shield valve fully - nothing! Still cold. I then turned my attention to the TRV (Siemens) and removed it. The 'pin' (bit sticking up) wouldn't move at all, wasn't sure how far it was supposed to be sticking up. Sprayed some WD40 on it and left it whilst I went to have another look at your video in case I wasn't doing it right. A few minutes later when I returned to the rad - Whoopee!! It was already hot, and the pin was noticeably sticking up further, and I was able to push it down and see that it was free. So thank you so much - you're an absolute star!! .....I have subscribed to your site so that I can return if I need any info another time.

[@jeremychurchill9489]

Brilliant video, thanks! We've just fixed a sticking valve pin on a Danfoss TRV - exactly as you described. Saved ourselves the callout fee and all the aggro of getting a plumber out (we live in the country and these things take time . . .). Have just watched the balancing video as well and - for the first time - actually begin to understand how the system works! Highly recommended!!

[@rajnishsingh405]

Much appreciation Plumberparts! Due to Covid my wife had to work from from home. But the radiator was not working in her room. After lots of complaints, I followed your advice. I had a problem with the TRV pin, and thanks to your tip of gently knocking the side, the pin opened up! I now have a radiator that works, and a happy wife!

[@HelloCactus1985]

I've never commented on a KZbin video before, but this video was so helpful. I'm an absolute DIY novice but I felt like a total pro being able to take apart and fix one of our radiators that wouldn't heat. Thanks for saving me a call to the plumber!

I can’t tell you how grateful I am for this. A very clear, easy to follow description. Many thanks.

[@luqmanmalik-os9zb]

Straight to the point! You didn’t spend ages talking about the reasons why it could be. Went straight it in to the possible fixes. After spending a minute or so on why someone is searching. Perfect! And thank you so much.

[@CookRacingUK]

Our bedroom rad hasn't worked for a year. Took off the TRV, wiggled the thin pin and it popped up a touch. Pressed it down a few times, making sure it was loose. Put the heating on and the rad came warm!! All thanks to you - much appreciated!

[@nickwilson7537]

Brilliant, thank you so much! My 1 year old’s room was the only radiator that wasn’t working, now it does thanks to following your advice. My issue was the stuck down pin in the valve. Thanks again!!

What causes radiators to be noisy. I have the old side on Thermostatic valves. At 2 it is quiet and the radiator is barely warm. At 3 it's boiling and you can hear the water rushing through or/and the radiator is noisy.. This radiator is upstairs.

Oh wow, watched this today & "fixed" the radiator today while my hubby was at work. When he came home he was totally amazed & wanted to know what Id done... Sorry to tell you Ive not admitted where I got the info from & loving the credit Im getting - I'll leave it till tomorrow & confess it was from this fab website. Thanks. ;-)

[@nikkik6727]

Thanks, our radiator issue was solved by the lockshield tip. After having tried everything else 2 years ago, we completely failed to think of messing with the lockshield and have used an electric radiator over winter in that room since then. I followed the instructions to open up the lockshield, and hey presto, a hot radiator :D :D :D

[@plumberparts]

BOOM! Well done Nikki!

[@jamesgrimwood1285]

Awesome! I live in a rented house, and this video has saved me the effort of having to get the letting agency to do something about it. I kind of knew it must be something simple and Google brought me here. The radiator in my office was stone cold, but full of water. Gently pulling on the pin in the TRV made the radiator instantly heat up, and now everything is nice and hot the pin moves around freely again. The hardest part was getting the TRV head off, it's secured with clips and a metal C ring and some old paint, and a bit of rust and clearly hasn't been removed in 20 years.

[@ArtistGuardianAngel]

Thank you for being one of those caring proffessionals that shares logical and well explained layman terms knowledge, I had one radiator stop working and British gas took it off clean it out (which I had already done having read on another video sludge could be a problem) and there was nothing coming out when he did it (obviously as I had already done it and told him), he put sludge buster in my water tank and basically gave up but said boiler was all good and other radiators and said maybe need floorboards ripping up to find problem 😲and that was that. I have lived with that issue for years until another radiator went cold then a a couple months later another one until today all but first and last had stopped working - having seen your video I carefully took off the regulator valve on each radiator and notice because i was in a hard water area the pins had locked down - i took your advice and gently wiggled them and cleaned them and immediately heard the rush sound and they heated up - everything fixed thanks to you and in 2022 with the fuels hikes and everything expensive and being unemployed this has save me an immense headache and stress! May you have great and happy times ahead for passing on good knowledge.

[@lisawilkes2615]

OMG Thank you so much for this really clear and precise video. I had 1 bedroom radiator that just would not come on while all the others in the house were lovely and hot. Watched your video and it worked within minutes. It was the lock shield valve that was not fully on - one quick turn with a spanner and I could hear the radiator come to life. Thank you so much. My husband passed away 6 years ago and he would have automatically known what to do but as a woman on my own things like this are difficult, but with wonderful you tube I can practically try and fix anything myself !!

Omg!!!!!! Here's me walking into my new house. My partner tells me the rads aren't working at the entire front of the house..."move out the way Bab" I said, holding onto a bleed key like a holy chalice "I'll sort it"...bled the rads, and nothing happened, quite emasculating. So I told my partner, we'll need to call a plumber. 30 days had passed, still hadn't called a plumber. Thought I'd give research one more shot, and came across your vid. Longer story, short...turns out it was the pin that was stuck. Nice toasty rooms now. My partner now calls me Mario. Thank you so much because not only have I now got super hot rads, I'm now my child hood gaming hero to my partner. 👍👍👍👍👍💪💪💪💪

thanks mate, invaluable info on rads everyone should know

[@majorpygge-phartt2643]

For those who are not plumbers, don't forget if you start adjusting your lockshield valve it will need balancing again afterwards to get the correct flow through your radiator, or else you can cause further problems elsewhere in your system, as well as with that first problem rad.

[@Norton1531]

Can't thank you enough!!! Rad has been freezing for ages, never knew what it was. Bled it a few times and it made no difference. Saw this video and checked the TRV. The little pin seemed fine, so I first thought that wasn't the problem. Gave it a little wiggle anyway. The rad started getting warm instantly, and was nice and hot before I could even screw the TRV back on! I'm gonna be nice and warm when I go for a poo now, all thanks to you! Cheers!!!
