I watched this a few months ago but didn't have any troublesome radiators, just rewatched now with a problematic radiator and it worked a treat, thank you. 👏👍🏼

[@MrEmilyg]

Excellent tutorial. My living room radiator was warm at the top cold at the bottom after watching your video I rather nervously followed your instructions, and managed to drain, remove and flush it through and after re fitting and bleeding its working perfectly. Excellent work 👏 keep up your fantastic videos

[@TheDIYGuy1]

Will do, thanks a lot

[@sarahjames5673]

Can you please advice on what if the radiator doesn't have a valve at the top to bleed?

[@cuddleaddict1]

I was going to call a plumber but watched your video first, am so glad I did because I’ve only gone and fixed it myself! Woohoo! Proper chuffed with myself! Thank you for the video, I’ve subscribed and gonna look through your library to see what else I can fix 😄

[@Militant69]

Top man thank you, as a bloke with zero DIY abiities, simply giving the TVR valve a few taps got it working for me, the pin is pretty stuck though, as in it doesnt move up and down. But what was once a cold radiator is now fully hot! And the Mrs thinks I'm a genius.

[@waseleyontour]

Thanks so much for this. It was a trapped pin in mine. Really appreciate this. I’d spent the last 2 days bleeding all the radiators in the house. Then this video sorted it for me in 5 mins. Thanks again. You’re a star.

[@lindalwilson3823]

Thank you so much, I am a woman on my own who has a freezing cold bedroom for just over a year, followed your advice with a gentle tap and wallah I now have a wonderful warm bedroom, plus I bled my lounge radiator which by the way had a lot of air in it to now having a full warm radiator 😊

[@npc3743]

Hi, Just followed your advice and in 2 minutes I freed the pin inside the thermostatic valve and hey presto hot water again in the radiator. Many thanks you just saved me some money, I think your advice is first class. Nick

[@billyblackie9417]

Really helpful guide to look out for if there is a problem with the radiator that the house holder can try before calling someone in to charge big money for something the home owner could do. Great tutorial guide and well compiled for ordinary people who would struggle to figure out a problem. I will have to rewatch this video a few more times to catch and more understand these hints. Especially which valve brings water in and which valve let's it out of rads and which way to turn valve to turn off or on the rad. Great job as usual to you and your great talent reaching out to ordinary people. Thank you so much

Hello, your explanation is really good and effectively worked. I saw more than 5 similar videos but you are the best among them. I just finished fixing my radiator by pulling out heat level packet, and by gently pushing it. Many thanks and good luck to you.

Brilliant! Had a cold bathroom all winter, though tapping the valve didn't work I pulled the pin with some long nosed pliers. Radiator is toasty now 🙂

[@TheDIYGuy1]

Glad it helped

[@jeremyrichards8327]

Good simple basic explanation. My hall radiator was not working and as the thermostat was just up the stairs the heating was unregulated. The input was hot but the radiator failed to respond until my wife said she would call a plumber and a few days later it worked perfectly! Possibly a small blockage which cleared itself. Seriously I had flushed a bedroom radiator last year and was amazed at the gunge which came out. I have put thermostatic valves on nearly all now and keep an eye on their condition. Presumably a Norfolk boy like myself.

[@TheDIYGuy1]

Yep, Norfolk too 👍

[@peterturner717]

Followed your instructions and now have a lovely hot radiator, Many Thanks

Thank u soo much for this video, my bedroom radiator was stone cold. I tried doing what u suggested...removed the thermostat valve and pressed gently on TRV pin....and bingo...hot radiator!! Easy as that !! Thank u so much

[@TheDIYGuy1]

Glad it helped

[@tectorama]

On older, non pressurized systems, its a good idea to turn the heating off before bleeding the radiators, as it is possibly to pull air in rather than release it. It's also a good idea to loosen off the actuator head in the summer. If the pin is stuck, you can often free it by using a pair of pliers to gently ease it up, not pulling up and pulling the pin right out. Heating engineers love TRVs, as it's a good earner going around changing them. I would never have one in my house.

[@lisaryan8185]

Thanks to your video, now fixed my cold radiator. 👌

[@dalanwest8850]

Saved me a lot of hassle there! mate! Can’t get plumbers to come out for small jobs these days but it was just a stuck TRV pin, sorted in ten mins thanks to your video!👍🏻

[@TheDIYGuy1]

Your welcome 👍

[@Metal05]

Problem is that “small job”, needs an experienced engineer to sort for you or you’d easily do it yourself. Vans run on fuel, they cost to insure, public liability to pay for etc. £85 minimum I charge for something local like that. You are paying for experience not time. Customers think it’s expensive because they think you’ve only been here 10 mins. Then they think we are ripping them off, but we are not. If you are a self employed plumber you’ll realise quickly the reason why we don’t go to “small jobs”.

[@grandtourerpt]

​@@Metal05 the problem is not the price. I've had plumbers give me exorbitant fees for a small job and I said sure, when can you come by, and all I get is silence after that. Why reply with a high fee and then ignore the customer when he agrees to it? And it's not just plumbers, other trades are the same.

I have the same issue (although no TRV) in that there is not heat to either pipe - do wee assume therefore its a smudge build up blocking the input pipe ?

[@cdh601]

Just a little tip that may help with the stuck TRV ..shut the lockshield valve now open bleed valve, now the system pressure is pushing on the TRV should now find it easier to release . Also should mention if bleeding the radiators and especially with a combi boiler the pressure would need checking after as if it falls to low the boiler will shut down . Always enjoy your videos tho 👏

Thanks for showing this, the problem was indeed a stuck pin, but your pressing and tapping didn't fix it. So I went to the DIY store to buy a new TRV and they suggested trying WD40 on the pin, before changing it. That did the trick, so you might want to add that to your suggestions. You did give me the confidence to get started though!

[@TheDIYGuy1]

Thanks. Good tip, not something I usually try that one.

[@baz5973]

Cheers matey, followed your expert advice, it was the TRV pin stuck. My only prob was removing said TRV head, it was a different collar/ make, I used grips and it came off. Hope I have not broken it. Hell of a job to put it back, so at the minute have left it off and will have another go tomorrow. Sure enoug applied downward pressure to the pin and it released, radiator toasty now. Thanks alot, have already subscribed as I do like your format and also the tools you use. Cheers.

[@keithletheren196]

Be aware that if it’s really cold and you remove the radiators, the TRV will let water out. They usually come with a closing lock cap which you should use. I found this out the hard way when I left a rad off overnight and found the floor soaking wet the next morning

[@rodgerq]

You can normally close it right down which closes it stopping it being able to open. But yeah now that you mention it, I've probably just never left one in such a cold environment that it's had the opportunity to open on that low setting(which I had presumed was off)

I was same , but lucky as I spotted water coming out .I searched around and found a small button battery that I put on top of the pin and re screwed the valve down and it shut the water off till I got the rad back on next day .

Great tips! When refilling a radiator it's a good idea to add some inhibitor to prevent build-up of sludge in the system. I once had a system with so much sludge it stopped the boiler working and it all had to be flushed out.

[@TheDIYGuy1]

Absolutely right. I've saved inhibitor for a separate video

[@TheD7035]

@@TheDIYGuy1 Hi, Happy Christmas, I -eventually- found the “sludge” inside my (open vented) Y system had gone really hard in most places around the pump causing it to almost stop completely. This resulted in the copper pipe work system making banging noises! The “sludge” had also gone hard and almost blocked the water refill T section pipe work just before the pump” and had also narrowed the 22mm overflow vent pipe to the small loft tank. I noticed a small magnet I used actually stuck to most the copper pipe work near the pump ( copper does not magnetize so a good test for sludge inside such pipe work I understand.) So we got the pipe work, pump, 3 port valve replaced and put 2 lots of x100 inhibitor. So far so good. A good video thank you.

[@John-ob7dh]

I found a solution to a cold rad .I turn off all the rads except the cold one / ones .Then I put heating full on for about a hour and it seems to burn off the air in the rads. ( I had already tried bleeding them with little success.

I have a faulty filling loop causing the boiler to overfill after a few days. I have been waiting forever and a day for the housing association to come and fix it. I have had to bleed water from the rad so often I think there's no more inhibitor left and now my rad in the lounge won't let the water flow through the rad out of the outlet. Now watching this video I think it's sludge build up. The trouble is it's a long double rad and it's a beast.

Followed your tutorial which was excellent! Managed to get sludge out of radiator however the radiator is still cold when the heating is on. Checked the pin and it's not stuck.
