How to stop noise from a radiator valve.

[@WestieWestie]

Thanks so much for this video. One of mum's radiators has been banging for years, despite an engineer coming out to fix it! I had a look at the radiator and the wrong thermostat valve had indeed been fitted ! All sorted now though thanks to you. :-)

[@dereton33]

Glad it helped

[@Finglesham]

Lots of sensible advice. My problem is that my valves were fine until recently I had a new Worcester Bosch 30iery fitted. It is still a system boiler and pressurized. No I have three rads bang at a certain time after the heating has been on, perhaps 2 minutes. I fitted these valves , some years ago, I am thinking that the are worn out. Before had a floor mounted 80K Ideal boiler 44 ears old. This worked fine and never had any banging.

[@dereton33]

Once you change something like a boiler that is when the problems begin.

helped right away!! didn’t even have to watch the whole video, i just turned the knob and it stopped lol!!

I can't sleep science I moved to a new house because of that noise. I checked the valves and you are right. They put them in the wrong position. I least I know now how to atack the land lord. Thank you !! :)

No problem.

How to check if they are in the right position? Help

Thanks for this I have the same noise coming from the valve but it stops after about 10min of the heating being on. Would this be the same problem?

Yes it will

Thank you so much for posting this video! We’ve had about a dozen contractors that haven’t been able to resolve this problem. Your video solved the problem! Thank you! Thank you!

No problem Jeff.

[@KostadinBelchev]

I have the same banging noise problem, however I have a double pipe valve and the flows are reversed. I cannot easily find a double pipe valve that runs both ways, mine has an arrow and the plumber installed it the wrong way, no easy way to revers the pipes since they come strait out of the wall. Will opening the by-pass valve on that double pipe valve help with this issue?

[@dereton33]

Worth a try.

[@KostadinBelchev]

@@dereton33 Thanks for the reply, I found a way to switch the pipes from the distribution box and this has fixed the issue for now. I cannot tell you how grateful I am for your video.

isn't is a bi-directional valve? It has arrows on the side going both ways

[@dereton33]

Hi mate how are you doing? Love your channel and am always trying to get people to watch your video on Heat pumps, so well explained. O those valves are bidirectional but never seem to work properly when fitted on the return always seem to make a noise but only on some systems, my one pipe system is fine, but my friends was making a noise on shut off until I put the valve on the flow. All the best and once again a great channel you have there.

[@warrenspence7372]

A new boiler was fitted a 5 years ago, there are 6 radiators in the house several of which were noisy. It sounded like water rushing through too quickly. I turned down the lockshield valves and the radiators did go quieter but had cold spots. I then opened them all up full, they are now nice and hot and all silent bar one, any suggestions ha? Cheers Warren

[@dereton33]

Try adjusting the one by using the opposite valve.

[@belsspace2498]

Hello please help me all of my radiators are making this noise I have no clue what to do

[@dereton33]

Turn the pump speed down.

[@Nightowl2512]

Hi Al. My radiator in the bedroom made that kinda noise sounded a bit like a helicopter. When i went upstairs i found it was the old radiator i turned the very old value down slightly and it stopped. Ive lived here 2 years got a new boiler last year so its been flushed would changing the valuve myself be worth doing im not sure from this video? Help

[@dereton33]

No save yourself the trouble, it was just a balancing issue.

[@barraidh5l]

Do you only have to replace the valve to stop the noise? Or do you have to replace the pipe fitment?

[@dereton33]

Just the valve.

[@andylee3153]

My radiator has started doing exactly that but it’s a modern thermostat with two arrows and appears to be on the flow. What could be wrong?

[@dereton33]

Try cracking open the locksheild valve another turn.

[@andylee3153]

@@dereton33 thanks, that worked

[@EmaiaE]

My radiators make a whistling noise not sure what the issue is, any help would be appreciated

[@dereton33]

Try adjusting the locksheild valve on the offending rads.

@@dereton33 thank you very much, I’ll give it a try and report back

[@samcaldwell6449]

same knocking, i have on a Myson 2 way TRV, looks the same as your first TRV , is this the same as a reversible flow valve?

[@dereton33]

Some of the older ones are not the reversible ones, so check it is on the flow and not the return.

[@hillside5575]

I have increasingly noisy pipes, think the plastic pipe clips have opened up. It was a poor install many years back. Any tips when I lift the floor boards to secure the pipes properly? I’m sure some are touching joists as well.

[@dereton33]

Make sure they are lagged as well. Also use clamp over clips.

[@hillside5575]

@@dereton33 thank you advice! I’ll add proper clamps and lag. Your videos have saved me a fortune in tackling basic plumbing.

Sometimes having the pump speed set to high can cause noisey valves 👍👍👍

Great point! PB.

[@gregz1984]

So my problem start with similar noises since fit new baxi boiler.Already notice I've got valves on return. Now need to check if they are reversible. Cheers for info.

[@johncolebourne2672]

Hi love all your videos. I've just had a combi boiler fitted and trv fitted to rads I to have the same sound, so not sure why this would happen

[@dereton33]

Try re-balancing the system.

[@davidoshea1536]

Brilliant video Alan 👌 as always 🔥. I hadn't heard that noise before, when a an older trv had been fitted on the return, instead of the flow very interesting bud.⭐

[@JuiceBanger1]

In my last house I had noticed I could now hear the flow or whoosh of water in a rad when the heat was on, dont think it did it before. I had to turn the trv down 1 notch to stop the noise

[@dereton33]

Could be round the wrong way. Still you have left that all behind.

[@JuiceBanger1]

@@dereton33 yes im in the new house a month today , reading up on how the pressurised hot water heating system works and the megaflow tank upstairs. I seen last week the pressure gauge was quite low at about one quarter bar. Now I had tried 3 rads with a quick bleed but i presume it was already low moving in. Anyway figured out how to repressure and let it build to 2 notches above 1 bar. Now 4 or 5 days later the pressure gauge has dropped just over 3 notches on the gauge. Sitting below 1 bar now. Have I an issue?

[@benpacy139]

Any idea what could be causing a high pitch whistling from a TRV? When you turn the valve slightly it stops but then starts again hours later? Cheers

[@dereton33]

Valve whistle, try opening the lockshield valve another turn.

Hi Al, can you please help me. I just got a new boiler fitted and since then 3 of my TRVs are making this noise. Does it need balancing out or new TRVS? Please can you help? X

[@dereton33]

Try balancing them, but they may be the old TVRS that are on the wrong way round, IE return and not the flow. Turn your heating on from cold put your hands on the pipes to see which heats up first that pipe will be the flow.

[@aishah54321]

@@dereton33 thanks. Does the trv need fitting to the flow pipe?

[@elisab7652]

Hi Al, slightly unrelated question but wondering if you had any advice to offer. What is the likelihood of having two stopcock under the kitchen sink? We have located one and we have turned it off but water is still running from the tap. Could there be another one further dow (the rest of the mais water pipe in the kitchen is hidden behind a wooden panel) that actually turns the water off and the other one is maybe for something like the washing machine? Cheers!!

[@dereton33]

Hi it often happens, that there are two stopcocks, turn the other one off as well, see what happens.

[@tomelliott90]

Hi mate, I have a mix of standard manual trv's and smart honeywell smart trv's in my newbuild however whenever the rooms reach the desired temperature, the valves (both types) make a banging sound. I physically have to turn it either way to stop the noise. The valves are all on the return pipes but all have the multi-directional flow arrows. Any ideas?? Ps love your content, has helped me loads over the years. Cheers pal.

[@dereton33]

Hi Tom, it is a sad fact that although the valves have either direction fitting on them that they always make a noise when not fitted on the flow pipes.

[@tomelliott90]

@dereton33 thanks for the reply! Would I have to literally swap the trv's and lockshields on every rad in the house then? If so, do you have any videos showing how to do this? Thanks again 😃

[@aliglfreeman]

Hi Alan, thanks for the video. I have a similar issue. I checked the flow/return, but the valves/thermostats are on the flow side. My situation is odd, as this problem only started after I had my boiler replaced. I went from a system boiler to a combi boiler. My radiators and pipe work are a fair age, the majority have micro bore pipe but the large living room radiator has 15mm pipe. The radiator with 15mm pipe doesn’t have the issue and coincidentally was fitted with a new valve, as the previous was leaking. Come to think of it, before the boiler was switched, I changed out all the thermostats, but never changed the valves. I’m wondering now, would changing all the other valves be a good place to start?

[@dereton33]

Yes give it a go. The lockshield valves are very cheap.

[@NivagSwerdna]

That banging is dreadful! Mine whistle occasionally. if I tweak them it stops.

Just keep tweeking em. Ha ha.

Don't bother with thermostatic valves they don't really work and make a constant noise

[@dereton33]

If that`s your view, I don`t think a lot of people will agree with you.

[@henry9406]

I work in a care home and the chattering problem was so bad that I removed two of them and just controlled the flow with the valve at the other end of the radiator, two weeks in and ok but it hasn’t got cold yet
