- Freeing stuck radiator valves, Especially lockshield ones. Sometimes they are so stiff to turn on or off.

This is exactly what I was looking for - perfect timing. Your explanations are the best
Glad it was helpful!
Thank you so much. I nearly gave up but was able to tighten it after following this advice. Now my room isn't a sauna.
Excellent!
Thanks - a well-crafted video by a friendly and obviously very professional plumber. Very useful to me and soooo much better than almost every video I’ve seen on the topic!
Thanks a lot Jim.
I don’t know why I didn’t look for this video years ago. I have a few radiators in rooms I don’t use but they were stuck on. With energy prices going up I was determined to turn them off-worked a treat, thank you!
Right on
Thanks. Recently changed a few rads for columns etc. One old rad I removed when I removed the pipework and had a go adjusting the locksheild with a spanner it broke clean off. Today I am balancing the system and one locksheild was stuck, I prefer to use those twist caps to see if I can do it by hand first and this one wasn't budging. A bit of spray lube and gentle turn with the spanner moved it. You have great videos, you address a lot of minor problems not on RUclips!
Glad I could help
Thank you so much after weeks of trying to open I followed you too and just managed to bleed my rad so pleased with myself
No problem.
WD40 worked a treat! Finally got the radiator in our bathroom working over three years wondering what on earth was going wrong. Thanks for the video.
Great to hear!
Cheers Al, very much appreciated 👍
Any time, all the best mate.
Thanks for video my radiator valve was stuck and I brought some WD40 and it instantly worked to unstick the valve , now I can use my radiator 👍👍👍
That`s great.
Thank you! This was fantastic and just what I needed
You're so welcome!
Thank you! Mine was so stuck, and i don't know about plamming, you helped me : )
You are welcome!
Great video, thanks for the tips. Was just what I was looking for!
No problem 😊
you're a lifesaver, can't thank you enough for this video!!
No problem.
Thank you, worked through your instructions and when I removed the gland nut and gave a soak in WD40 I was able to free the seated valve. Excellent tip and radiator valve opened just in time for the colder weather.
Excellent!
Thank you. Just used this advice ☺️👍👍
Excellent!
Thanks for this video. Helped me out!
No problem!
great video, thanks!
Glad you liked it!
Great tip thanks 👌
No problem 👍
dereton comes good again. sorted!!!
No problem.
I have one of these I can't turn off because the previous tenant rounded off the valve. Costing me a fortune! Tried all these and no luck, but it'sthe closest I've gotten yet. Maybe I'm too weak!
Thanks as always for the vid!
Sorry to hear that.
Could try mole grips or adjustable spanners with a lockable grip and try them in conjunction with the tips in the video.
Worth a try
If you're renting and the previous tenant did it, surely this is something that the landlord should sort out?
@@garethnicholas8106 good point, I misread and thought she was the landlady.
Thank you. My nanas radiator in am empty is stuck on full blast. I'm going to try this later
Good luck!
just fixed my rad !! thanks
You are welcome!
Love the way u dragged usual place hahah
Always! Ha ha.
thank you!
No problem.
cheers mate
No problem.
I have just bought my first house and found that the radiator in the office room was stuck completely off, couldn't budge it and was so cold! Found this video and managed to get it going in no time, lifesaver thank you soooo much! Just one question - turning the nut also turned the pin that was stuck,however I assume the nut should really be left screwed down tight. The pin and the nut don't seem to be able to be turned independently of each other. Is it ok to leave the nut unscrewed a few twists as long as it's not leakng? It's an old house and the valve is jammed up close to the radiator so it's extremely hard to get a good angle on it for adjustments!
Yes it should be fine.
Worked for me. Had to take the gland nut off and wait a minute for the oil to soak in but then it freed. All my other rad valves are locked up too due to my lack of an annual maintenance cycle which I shall now attend to. One problem is my valves are horizontal and close to the floor so very hard to get a normal spanner to turn. Is there a valve socket spanner tool to accommodate this situation?
No might be nest to us a small socket set.
What size is the adjustable spanner that you are using? The rad without a TRV is on full blast near the thermometer and making noise. I'm just wondering if turning it down would give the rooms downstairs a chance to heat up before the thermometer switches off and also reduce the noise. Also I've undone TRV top with the screw in it, and I'm trying to turn it, but it's not budging with stanley 74-266 pliers fat max pliers - I'm wondering if it's because the nose is too short on it and need more longer nose pliers. Would me reducing the heat effect it negatively at all? Many thanks, Robert.
The spanner is a 6 inch adjustable. You cannot adjust or turn a TRV valve., only thumb wheel valves. Reducing the heat to it will force the room stat to require more heat, so it would heat the rest of the house more.
Have this same problem...valve stuck,unable to move left or right..tried doing what you said : loosen the gland nut, but water started squirting out under high pressure ?
Try just loosing the valve a small amount so not much water comes out. Then try grips on the valve.
Can the temperature on a bypass radiator be turned down without effecting the rest of the radiators? Mine is on all the time and costing a lot of money?
Yes turn it right down to as low as you can get away with.
Tight nuts... tell me about it! My bathroom hot-water tap washer needs changing (1st time since 1967) as the tap head is seized rock solid! Measured the nut which is in need of a 22mm spanner... I'll be buying one tomorrow, in hope, aaaargh! Any suggestions would be much appreciated? 🔧
Buy easy tap splitter kit
Yes a good kit, but a bit expensive, unless you are a plumber when you would use it more often making it worth the cost.
@@dereton33 buy a 3/8 breaker bar and a 22mm socket hold the tap in place and crack it loose. 👍👍👍
Just a quick question. Is it best to solder radiator pipes or use compression fittings where the joints are underground and the pipes lagged? Thanks.
Solder, best never to use compression on heating pipes.
@@dereton33 thanks. The plumber in the shop and the plumber that came to look at it both think it's okay. Don't know what to do now.
The knob keeps on turning on but it doesn't stop turning. The actual valve inside doesn't move and it's stuck in the closed position. Do I need to replace the lockshield valve?
Just the knob change it for a thumbwheel type.
The parents have a few radiators that haven’t been turned on since they bought the place over 40 years ago. (Small toilet & end of corridor). The valves are unsurprisingly jammed. They live in a hard water area. Is there a risk that trying to unlock them like this could crack the valves and lead to a leak? Would hate to attempt this over Christmas when I’m home and flood the place or leave them without heating for the winter. Any thoughts? Thanks a mill 🙏
No should be fine.
Amazing. Thank you for the speedy reply 😊
Is that left hand thread? Looked like you were turning right to open?
No its a right hand.
Any advice if the tip of the lockshield valve snaps off 🤦🏻♀️?
A small pair of 8 inch stillsons will grip around the round brass shank.
hi could you suggest any ideas for jammed Milano radiator valves
A well fitting small spanner. 👌
The lockshield valves are not always easily accessible - I have two with no room for pliers / hands. And then I found to my surprise that there are NO KEYS / WRENCH SOCKETS for this type of spindle (flat) - literaly NONE! How can this be, when they are so common and when usually there are specialised tools for about every odd job. But not for these. You want to turn the lockshield valve - use pliers...
Ideally, I would need one just like those long t-bar stop cock keys. And so I ended up "manufacturing" the key of my own...
Welcome to the Plumbing world.
I've tried wd40 and still won't turn? Any suggestions please
A good size adjustable or fixed spanner.
How do you get the white cover off if it’s a screw on and it’s corridated
Undo the screw, then tug like mad on the cap and it will come off.
@@dereton33 the screwdriver won’t work on it as it’s all rusted might use a hack saw and make myself another part to put the screw driver in
My valve is on top and is like a cap, stuck closed, it gets slightly warm at the bottom
You have air in the radiator, also check that valve is turned on.
@@dereton33 yeah they all have to be bled, I'll see if the valve is on, thx
Is this the old-style of valve, with a larger nut than most moderns fitting screwing on to the tail? If so, it's what I have on my old (imperial-sized) radiators. I'd really appreciate knowing what that fitting is called, and its size, as I'm in need of swapping old manual valves for new TRVs, and am not sure what I should be searching for. I suspect removing the old tails could be quite difficult, so a direct swap would be ideal if I can find the right size TRV. You referred to them in your other video (ruclips.net/video/fws55kOE5aY/видео.html), but didn't specify the size of fitting. Thanks.
If you are swapping out for TVRS then you can only get the standard 15 mm size with the small 15 mm nut not the old fashioned 22 mm nut as you have. So you will have to remove the old tails to fit them.
@@dereton33 I took the plunge, bought a radiator spanner and three low-cost TRVs and drained down the system. Thankfully, I had a 3ft metal pole to hand as it would have been impossible to unscrew the old tails without that extra, carefully applied, leverage on the key. All now fitted and working, with Sentinel x400 in the 30 year old system, with a second drain-down and some further TRVs and inhibitor scheduled for a couple of weeks time. I really appreciate your no-nonsense videos, and now feel brave enough to rebalance the radiators afterwards, too.
@@VC57UK 👍☺️
WD40! THANK YOU THANK YOU
Your video worked a treat 🎉🎉🎉
No problem 😊
