Excellent Al, I've been a plumbing and heating engineer for almost 15 years. I still learn a thing a or two from watching your uploads. You're a top man, I hope both Jan and yourself are doing well. 👍

Having decorated the room and removed and painted the radiator, I reconnected the radiator and when turning the rad valve back on the top of the brass valve snapped off. So new rad valve required. Having seen how the water splashed up the wall in you video I hung polythine sheeting up on the wall, loads of old towls around the pipe and then followed your instructions. Success, no dirty water over wall or floor and a new trv fitted to rad as an upgrade. Thank you Dereton33.

Thanks Al you just saved us £250 and it was great to have a go and an amazing feeling when it worked. Thank you so much!! for making this. With everything going up in price at the moment, this was such a relief not to have to fork out to have replaced for a small chrome bathroom radiator in the downstairs loo. Thank you for warning about all the moments when the heart beats a little quicker. I stayed calm even when the nut didn’t initially grip and then all went to plan. 👨‍🔧👍

Love watching your videos, followed you for years, extremely helpful videos, you can't buy experience 🙂

Your garden is look fantastic as always Al 👍

Thanks for sharing! A really helpful video, explaining the "why", the "what" and the "how", especially the hose fall back procedure. Feel more confident about doing it myself! Cheers!

I see why it’s not for the faint hearted when that dirty water splatted on your wall towel and all lol!

I’m going to show this video to my plumber tomorrow !

LOVE watching your videos please keep them up.

Like these videos, good to brush up and see how other people do things. For people thinking of quick changes, be careful, drain off excess pressure first via bleed valve. Also I would never do this unless the floor does NOT have carpets. I.e. kitchen or bathroom.

Brilliant, thank you for the information and demonstration. Cheers 🍻 regards, Chris.

Thanks just what I was looking for.

Perfectly, most patiently shown and explained. Compliments. 👍 👌

Quickest hands in Kent 👍

Useful quick flip tip. Thanks

Hi Al, and Jan 😰 this gave me a laugh , fastest thumb in the south mate, your a star act, but a great practical demo , many thanks for another great tip, stay safe guys, best wishe's, Stuart uk

Have done that with isolation valves to at times if had to quite daunting Al

Hi Al. I have some of those rad vavles that have a drain off spout which also have like a 'lock nut'' and square spigot on the end to open the drain. Im not certain of the correct procedure to open and close these correctly. Are you supposed to wind back the lock nut then turn the spigot to open the drain then the reverse to close? I noticed a little leakage when I did drain off some water even though both the lock nut and spigot seemed to be tight. Could you do a vid on these valves, please?

Great vid

brilliant video,

Nicely done

Thanks Al - might it be worth taking the pressure out of the system by bleeding it out so the force of water isn't as strong or is it not worth the effort?

@07:37 Cut pipe can be really sharp. I'd recommend a rubber or leather glove. I have thick skin. Literally and metaphorically. Non cut/bloodied thumb up, Al.

Hi Al Can I ask a question I have a leaking valve on down stairs rad .was thinking of doing your quick flip method .should I shut off all rads on the system to reduce flow when I disconnect old valve from Pipe .my system is pressurised 1bar approx Thanks for all your useful knowledge Martin

Hi Al, If I can ask you a question. I have an old Drayton radiator control knob that I need to replace. Will a Drayton TVR control Knob be okay, or will I have to replace the full valve aswell? I tried to replace it with a Danfoss but the knurled ring wouldn't screw on it seemed to be the wrong size. Any advice you can give me will be appreciated, Cheers

Thanks for informative video. I have a question, will the water be hot if the heating has been on? Do i need to turn the heating off for a while before i try this? Thanks

There goes my money again... LOL. Great video--keep them coming.

I'm not a plumber and might be wrong, but judging from the colour of the water on the wall Wouldn't be better to drain the system and put an inhibitor into that system? As I've said I am not plumber (work in welding btw) and need to put a new radiator on the wall, this is why I watch a lot of that stuff recently. Have a few questions as well. 1.What is better to use ptfe tape or jointing compound for (new) olives, inserts. 2. Do I need turn my boiler off when draining the system. (Have to drain the system because radiator pipes don't have l/s and trv on just end cups. If you find a minute to answer these questions I would well appreciate it. Thanks

Hi mate the opposite side of my radiator don’t work so it would be the thermostat side that you turned off first can I do the same fix as you done just with the thermostat side instead ? Thanks

enjoyed your video,well explained.1 problem thou with me ,is that i have rads that were installed 1976 and i have got 2 pipes going in 1 side (to turn on/off) and what a plonker i was,i cut off pipe that goes inside the rad so i need to renew and flush/clean all the rads in the house,have you any advice,thanks ,mark. Reading Berkshire.uk

Ooh livin' dangerously there, Al! Shoot from the hip, that's what I say! 😁

Thank you 😊

I have a towel radiator and the valves are at the bottom but on one side (where you balance it) its rusty just above and the white paint is flaking off. I loosened the 2 thread's enough to put some PTFE tape on and it seems to have stopped the leak. Shall I just sand the rust off and paint it, or change everything?

When replacing a radiator, can the thermostatic valve be fitted at either end?

Is it possible to have all radiator valves removed, 11 radiators and put on new thermostatic valves without draining the system? Or because there's so many and the time it takes that the system must be drained anyhow?

the top of my valve is missing the plastic top so to turn on the radiator I use a pliers I noticed it leaks a little near the top Is this because the cap is missing or do I need to replace the valve?

I checked this video again to do with the statement if you have a Combi no need to drain off, issue is if its a bungalow with the pipe work in loft dropping into rooms it pours out, it did with mine.

Hi. My radiator has corroded. I’ve turned the ordinary valve off. But the TVR only goes to the frost mode and not zero

If this was a open vent system wouldn't it be easier to bung the two pipes in the f&e tank, depressurise the radiator in question and as such vastly reduce any pressure/flow in that section of the CH system before changing the valves?

Quick question... I'm guessing you would have to bleed the air out the system afterwards? How would you do that? And is it just the one rad u would have to bleed? Kind regards

Can you give us any tips or websites to show us how to edit you tube videos please.⭐️

If you've got wallpaper you could prop up an old umbrella to stop the dirty water gushing up the wall - or get the wife to hold up a towel.

..and you can bung the expansion tank and cap the vent if you have an open system.

Someone told me that on an f&e system you can plug the feed and expansion pipes with bungs and this air locks the system so you won't get much leakage. Not tried it myself though. It seems like if you are ok with getting into the loft then draining down is not much harder.

Maybe you could do a video on replacing a thermostatic valve Alan

Can you freeze the pipe with an ice pack from the freezer?

Great video but some cardboard to protect the wall would have looked better.

Just put a new pump on the central heating but the radiators down stairs are warm not hot.

Nice one Al......👍 I forgot to ask but do you live on the coast as I'm sure I keep hearing seagulls in your videos......😀

Worth a try in a bathroom.

Shocking mess not all advice is good advice defy not a sealed system I would advise any1 not to do this btw I'm a heating engineer in his 50's

Should jab took the pressure off lol😂
