- If you need to replace a radiator valve whether its a standard valve for another one or to replace a standard valve with a thermostatic valve or a thermostatic valve for a new thermostatic radiator valve. Then I have made this video for you.
I will explain in detailed step by step instructions, what's needed so you can replace the radiator valve with little fuss or mess.
I will pass you all my "Tips & Tricks" I have learnt over the years. Which other videos seem to miss out.
I will show you how to do all this with out draining the system. Saving you time and stress.
I have made two versions of this video the short basic version and a super extra extended version which is much longer. That video goes over all the problems and variations I come across when changing a valve.

Sharing your years of knowledge to help people out who can't afford an engineer is very generous. Thank You.
Great video first time changing a valve saved me money and I got the job done easy enough. Well done 👍
This is an absolutely brilliant video! Super informative, clear and helpful. Thanks for taking the time to create and post (both) of these videos. I'm an avid DIY'er and love to have a go at things myself first, so this sort of video is exactly what TH-cam was created for IMO. Thanks!
Worked like a dream. Worked well on a lower floor radiator. Thanks for all your helpful advice.
Excellent comprehensive tutorial, thanks very much, gave my confidence to change a radiator valve.
Mark, you are brilliant. So generous with your tips and advice. I am about to embark upon changing a couple of TRVs and thought I was going to have to drain the entire system. This is brilliant advice. I've subscribed to your channel, so looking forward to more from you. Thank you
Great video Mark. Your approach worked perfectly for me - thank you. One thing some people might need to consider is where an adapter is used in a TRV (instead of a normal olive) to step down from 15mm to 10mm.
Wow, what a comprehensive demonstration! I have done DIY for years and changed rads etc. But never used this method. Didn't know it was ok to use the same olive on the pipe and I have always used PTFE tape on the nut threads! So definitely learned something today. Thanks for this, top job Mark.
Great video, told me exactly what I needed to know, job completed with no issues
Really excellent videos, changed my first TRV today having run around town finding some rubber bungs (Toolstation) to isolate my loft tank and depressurise the system. Following the process Mark described, a piece of cake, done in under an hour. Now have 5 more to do, total cost inc valves to complete everything just over £100, absolute bargain compared with a plumber (if you can find one). Thanks Mark, really helpful.
Yep, Marks literally robbing himself. These Internet "plumbers" and other tradesmen giving away experience for free never fails to amaze me.
@@frenchfrench4514 The main reason I've learned to do quite a lot of these basic jobs myself is that all the good tradesmen are very busy and I'd have to wait months. Even if it's a job that will take me a whole day (find out how to do it, visit the shops to find the bits I need and then spend hours methodically working through it, it's probably a one hour job for a professional and I find they're often not interested - they'd much rather take on bigger jobs so that they spend less time doing quotes, driving around from job to job and billing 5 different people. No complaints, they've got to make a living, but I'm not necessarily taking work away from anyone.
@@frenchfrench4514 The truth is - if you costed the homeowners time on a similar basis to a plumber. The time spent trying to find a plumber or getting one to respond and turn up, the homeowner taking time off work to be at the property then it is no wonder that for small jobs it is expedient to DIY (if you have the house). To be blunt - plumbers do not want this sort of work anyway - there are bigger fish to fry.
Great Video Mark, I have to replace a Bathroom towel radio, and this has given me the confidence to do this, as I have to change the valves as well.
Great video I'm someone who dose the basics in my own home and would have drained the system, but your way is far better, thanks for sharing
I always drain the system
Absolutly fantastic explanation, thank you so much for taking the time to make these videos you an absolute top heating engineer.
I successfully changed out 3 radiator valves for thermostatic valves based on your earlier video. Excellent videos! Thank you for producing them with brilliant detail and confidence inspiring tone!
Mark, great video, just done my valves without a hitch and very long title bleeding afterwards...just a thought, found an unused mastic spigot a perfect bung for the rad when the valve is pulled away, cut it with a 10mm tail once it was in and snug.....couldn't have done any of the rest of it without your help tho. Many thanks
Damn you, algorithm! Why didn’t you show me this video *yesterday*?
Excellent details about locking upstairs radiators and supporting valves. Thank you.
Thanks! Your video gave me the confidence to replace a faulty TRV that wouldn’t shut off - the added bonus of knowing what problems might arise helped me be prepared but luckily it was a straight swap
And this is the SHORT video???😯
I've used this approach for all my smart valves. 👍
Very good, detailed, explanation 👍
Thanks very much for this video. I wouldn't have called a plumber for something simple like this as I'm comfortable with DIY, but I just needed tips for the details which I could have searched and pieced together for ages but this video had everything in one place. Will be buying you a pint via the toolbox fund. Cheers.
Many thanks, great video which covers everything I think I need to know and without boring music in the background.👍
followed your directions everything went great , a fine tutorial thankyou
Thanks for the video. I had to change two valves after replacing an old downstairs radiator which is on a system with a combi boiler and my plumbing has never gone right before. This worked like a charm. Even to the extent that after allowing water to flow out of the existing valves, when i took the valve off no water came out at all. I had turned the boiler off (as the video advises) and all the other downstairs radiators off as well. The lack of water flowing from the pipes gave me the opportunity to remove the old olives and replace the nut Marvellous!
Thank you, this was a great tutorial and explained everything that I needed to know, all the little tips really helped. Thank you very much!
Very clear and thorough video. Thankyou.
Helpful, relevant and clear. Exactly what I needed, thank you 🙂
An impressive head of hair, sir! Respect!
WELL DONE MATE...KEEP UP THE GOOD WORK
Just fitted a radiator following your video. Saved us £200 plus and everything works. Cheers
Great tip... thanks Mark 👍🏾
Great Video, very useful tips. Thanks Mark.
Thank you simple and direct information
Thankyou for this video, I’ve always struggled with TRV’s and fitting radiators. I just followed your guide and managed to add two TRV’s to my CH in 2 hours, I did it without draining the system too which I didn’t think was possible.
Thanks Mark, This is the second video on this topic I've watched and yours is very clear on the steps and far more helpful as you are not confusing the story by trying to address Combi and gravity in the same video. I have found that the TRV is on the wrong end of the radiator and it has started making a right old racket! I will be trying it out on Saturday as my wife is away for the weekend giving me the chance to clear up if it goes bad!
Hi Friend . It was a proper explanation and good for the beginner: Thanks
9:08 - I can't remember where/why I was told to use PTFE on the threads, and have often wondered what's the point for exactly the reasons you gave. I just kept doing it anyway because that's what I've always done - glad you've put my mind at ease and I can now stop doing it! I guess it's the people you learn from knowing it's essential in some cases (e.g, outside taps) and getting in to the habit of doing it on everything without thinking about why.
PTFE on threads is not for sealing, teflon is the most lubricating substance there is. You put it on threads so you can tighten the nut up more past the point friction would allow you too, therfore being able to tighten the joint further and easier which in turn compresses the olive more and creates a better seal. No jointing compound needed then. This guy may have been in the trade a long time but this is the reason plumbers and mechanical engineers use ptfe on threads, plus i've never used ptfe tape to seal anything
@@Dtp2296 never used Teflon tape to seal? Not a gas fitter, then.
@@JasperJanssen and neither will you be if this governmnent carries on much more. None of you will be.
I consider myself a competent diy'er. My uncle who was a plumber taught me much and so has my mate in the trade.
I used Marks ideas here and changed a TRV and lockshield valve no problems AND removed the old olive as suggested.
These things are doable with the right tools, confidence and aptitude, I don't like the insinuation by many 'plumbers' that it shouldn't be touched or attempted by anyone other than them. It's just their money they are thinking of. As long as you are not a hamfisted halfwit and take your time and have the correct tools, you can do it.
I've seen many tradespeople do piss poor jobs at £100 per hour, I personally don't trust them,the good ones are too few.
Thanks Mark for taking the time to explain it thoroughly
Thank you for a very interesting and informative video Mark. During the course of my life I've changed many radiator valves. I have always drained the system. This video has shown me something I would never have thought of. The use of PTFE tape on the threads was also a surprise. I knew the olive sealed the valve but I have always taped the thread when reconnecting the valve. I am 71 years old and still learning. Thank you.
Thanks for that Mark, excellent informative video 👍
Best video covering this repair! Thanks for all the information
your explanations are brilliant thanks
Anxiety levels for a call back coming back down to manageable. Thank you very much. I'll contribute once I'm not running at a loss!
Great video. Exactly how I change my valves…👍 (keen DIY’er.) saves money on replacing inhibiter and in my case underfloor heating biocide which seems to be really expensive….
Thanks for this video , just changed a faulty radiator valve after watching this and it worked out a treat !
I wish that all plumbers are as good as you .... very well done
Another helpful video, I used a freeze pack to change a valve, which turned into a right mess as I needed to change the olive at the same time,hence the ice suddenly popped out and I had a nice waterfall. But watching this I can see the mistake I made with the pressure.
Hahaha, been there done that, felt like I was standing Under a waterfall, f only for 5 seconds before. Managed to stem the flow.
Thank you so much for this experience and understanding the process
Whilst looking at the thumbnail I thought the guy from the Hangover made a career change! Thanks for the tips on changing valves 👍🏻
Must be his twin
This is the best Video I've seen on this subject!
Thanks for great videos. I've now replaced 2 rads, including changing the 4 valves/tails, all new nuts and olives. Did buy an olive puller as too scared to try hacksaw method! Do any of your videos cover new bsp valve into heated towel rail - unsure about whether/where to use ptfe tape/jointing compound.
that was well explained, i was impressed!
Great tutorial! Couple of suggestions, releasing the system pressure from the air release is time consuming and depending on the type of air release can be very difficult to catch the water. Much quicker & cleaner to drain the pressure from the boiler drain point. While you are there, if the boiler is above the rad you are working on, it's helpful to either close the boiler isolation valves or just close the boilers auto air vent. This prevents air ingress and better holds the water inside the system while your working. Very nice to see your use of jointing compound on the olive faces, many 'professional' plumbers use no jointing medium at all!
👍👍👍
Agree with all you said. I would do it that way. Don't want people turning wrong valve as ever boiler is different. Thanks my friend 👍👍👍
The last thing you want to be touching are boiler isolation valves because they are never exercised the minute you shut them then open them the rubber o-ring inside splits and they start weeping from the spindles
@@adierob1 well said mate! stay the f away from boiler isolation
So Clear and Concise. Thanks a bunch Bud
Great video, thanks. I had two valves to replace, one upstairs and one downstairs. I managed to do both following your advice, and I'm an absolute beginner.
Brilliant! Cheers👍
I sometime use a 15mm compression cap on the tails to stop the water
Great well explained video
Good work I like yr video very informative
This is most excellent.
Huge thank you, really gave my the ability and confidence to change the valve on my radiator. Saved me alot of money on a call out and a plumber. Thanks again, really great video :)
Thank you. I found this video really useful. As a keen DIYer, I have always drained down the whole system when changing valves. Your method is so much simpler, saves time, the risk of unwanted air locks (which I've had) and of course water.
Q- Is it better to put the TRV on the flow side of the radiator?
Good to watch Mark, thank you.
A- I have just replaced the 10 TRVs on my o-l-d system with Evohome wireless controlled valves and this showed me the difference in feeding from Flow and Return sides of the radiator. Feeding from the Return side causes the room temp to vary more than if the radiator is fed from the Flow side. I have not worked out why, possibly compensation devices on the new valve head.
I have noticed that a few of the old valve heads have started to leak, they do operate more than a normal TRV. Guess what I will be doing when the weather warms up, if I don't follow your video first!
Nice tips
Clever guy so thoughtful & innovative!
This is just fantastic! Thank you so much, it saved me a pretty penny.
Very informative video, subscribed to your channel, many thanks
Great video, showing all the details.
Well done sir got me out of a tricky jam this vid did. thanks again
Great video thank you for sharing it
thanks easy and clear instruction
Great
Well explained
Thanks
Excellent tutorial 👌🏿 👍🏿
Brilliant video!
Thanks for your very helpful tutorial.
Excellent video. Thank you.
Liked and watched till the end! Helped a lot and gave some great tips, all changed and functioning again. Only issue I had was water coming back up the exit pipe. Didn't know how to stop this so used your kitchen roll trick👍
Awesome mark thankyou
What a lovely fellow. Great video, thanks for all the information
Re tapered joint. I bought a shank of hemp 40 years ago which I’m still using. Never had a a leak at that joint. ( plenty elsewhere) PTFE should be regarded as a lubricant. It has no bulking out property. Thanks for the video.
Excellent video, many thanks.
Informative video. Thanks
very helpfull,keep good work going
Excellent video
Hi Mark, very useful and I’ve learnt a lot. Is there any chance you could a couple of videos on how to deal with a cold radiator (even if you’ve bled all the air out),balancing, and dealing with a snapped bleed screw. I’ve spent hours with these problems in the past!
Robru shut all your rads off except the one thats cold
Then fire up the boiler it should heat up the rad
If it's old or if you haven't had enough inhibitor in your system, your radiator could be full of gunk - especially if it's at a low point in the system. In that case (drain and then) remove the radiator, take it outside and use a hose to force water through until it runs clear. Alternatively, buy a new radiator. Refit and try again 🤞
@@johnmckay1423 that’s good to know. Many thanks John!
@@tonyclough9844 thanks Tony
Great vid, not replacing the olive is slightly risky though.
Mark, brilliant Video and well presented. Easy to Follow. Just one point, I think you need a new Ice cream container for your water hehe... excellent video
Thanks for the video Mark.. I've fitted plenty of valves but felt I better have a refresher and good job I did,, there was a couple of things lets say slipped my mind,ha ,,So thanks again and great video
This what we need
Hi great video. Im just about to attempt this myself. I get the principle if the rad and bugibg it once the water slows, but just cant quite trust when I take the valve off the pipe from the floor how does water not spurt everywhere. Mine is a bottom rad so would the pressure from the upstairs rads not try rush out? Should I turn all other rads off? If so both sides or just the one?
Really informative. Thank you
Always useful to put full bore valves on the main supplies so that creating air locks thus no drain down of system is easier. Good also once or twice a year to test such valves as they can corrode and fail over time. Great video.
Glyn, glyn, glyn. Did you really just suggest full bore valves? On the main supplies??
@@JohnnyFontane528 YES! On each floor I have a couple of valves on the flow and return of the heating circuit which enables me to isolate that floor (or zone) whilst I carry out the work. In much the same way, I also always install a 40mm waste pipe which is connected to the waste water system when I install a header tank or hot water/heat sore, it is all about making future maintenance easier, planning in advance and enabling drain downs or value replacements so much easier.
Great vid and will help a lot of people. Just one thing i have to say only coz i found it funny. You said you rolled the carpet back. I dont think there was any carpet in the room coz there are no grippers on the edges. Also in one clip there is a unit on the floor with no carpet under it or any grippers there. 🥴
Hi Mark really in depth tutorial - thanks! How do I find a leak in my central heating system that is not showing itself? Been told it's probably under floor somewhere!!!
Hi Andrew, My system needed regular topping up and I assumed a leak. Turned out it was a faulty diaphragm in the expansion vessel in the combi, not holding pressure. Good luck.
I would add: to minimise draining, I would go round the whole house & shut off all rads at both ends first. Most of the water (and pressure) will stay in the rads, and its a good opportunity to check / lubricate all valves), plug off the top tank (or depressurise a sealed combi system); Also, I made my own tapered bungs to the size I want using a thin cardboard cone & filling it with silicone mastic - leave for a week till fully cured, then soak in water before rubbing off the cardboard. Always add 1L of corrosion inhibitor if you can, it acts as a lubricant apart from anything else. Nice vid, thanks.
I have done a radiator as a DIY. I shut off all radiators in the house at both ends. Then for the radiator I wanted to remove, I drained it at the radiator after scooping out as much loft tank water with a jug and shut off the mains fill with a towel to stop it filling the loft thank. Then I painted the radiator and put a TRV on. I did that to the loft tank to clean with a cloth and remove the scum water. There is a loft tank in my home. I then put inhibitor back in via the cleaning magnetic filter and refilled the system from the mains water in the loft tank. I also shut off the stop cock for peace of mind. Clean loft tank AND a new painted radiator and inhibitor.
@@rtyrtyrtyus Good job. 👍👍
Thank you so much! Really helped me out 👍
Brilliant 👏
Watching this video exactly because we can't afford to get a man out for 1 radiator. Not worth the time of anyone involved. Ours is actually a towel rail radiator so things are a bit different, but there's a lot to carry over from this vid. Top info, thanks!
I do love the bungs saved me many a time from an air lock
When you use an adjustable wrench, you should push into the sliding jaw. That way you are supporting/compressing the jaws rather than trying to pull them apart. You were tightening/loosening by pulling away from the slider etc. One of the first things i was taught in my early plumbing days.... Still a good video!
I like Your video a lot, but have one key observation. The thermostat itself should NEVER be above heating pipe. In this case it should be mounted horizontally not vertically. Vertically mounted themostat is heated with warm pipe below and "thinks" there is warmer in the room than it really is. This disrupts its regulatory capacity.
@@danimayb Principles of Physics.Chapter on heat convection, elementary school. Warm air heated by a pipe rises upward. It tricks the thermostat into thinking the room is already warm and closes the heater too early. The radiator will somehow work, but incorrectly.
that makes sense.
