We use those brackets now, all you need to do is mark your holes then attach the bracket to the vessel and tighten up the screws.
@Rich 934 Mate, could try my bro Drew? He's based in Wigan but doesn't mind a drive!
Dust sheets are rare in your area I understand
Over here in France we use a rigid bar that bolts to the wall with feed & vent connections and a 3/4 female thread for the vessel. Great system strong robust.
You also shit into holes.
I love your vids mate, helped me out loads in past and I’m sure will do in the future!
👍
danny smith cheers.
Can you do a review on that B&M rectangular bowl and also do you have a discount code to get money off the 99 pence.
I learn something every time i watch your video,s,I was totally unaware that these expansion vessels were a must on basically every combi boiler at least I think thats what your saying, and i will add there must be thousands of them out there with the extra vessel because we just did not know this , cheers again.
No.....water will expand by approx 4%. Most modern combis have an 8 litre expansion vessel in them....half water, half air. Therefore space to take up the expansion of 100 litres of water. Reading the MIs will tell you the maximum system volume that the internal vessel can cater for. If your system has more volume, then yes you will require additional expansion capacity
@@lancemallinson4470 Good comment! Most oil beasts hold a lot more water than your average gas beast too.
The nitrogen or air charge in the pressure vessel has to be the same pressure as the system operating pressure (you kind of mentioned that), the vessels on domestic sys normally come with a precharge of 3BAR, if you don't drop the pressure and the heating system fill pressure is set to 1 BAR then water will never enter the vessel bladder. Secondly, did you check the boiler expansion vessel to see if the vessel had lost its charge or the bag had split or had a blockage? BTW water expands by about 2.1% up to 100 Deg C so if the system capacity is 100 litre (which I doubt....a lot lower) you only need a six-litre vessel; the one on the boiler should be big enough. That expansion vessel you fitted is suitable for a system with a water content of 952 litres, well oversized. Also, it might have been an idea to put a lockshield valve on the pipe to the EV to allow isolation and draining for future pressure checks. Just saying.
Coyote thanks for the info coach
@@mrbachittarsingh9243 No problem bob bob, advice given on YT should be reasonably accurate don't you agree?
@@coyote5735 Wow...so salty! Mate, most of my expansion vessels I buy come with a pre-charge of 1.5 bar. And mate, bollocks to EXACTLY specifying a expansion vessel for a few easy to understand reasons...1. What if another tosser came in and bangs a new extension in....can you trust them to install a larger vessel? 2. Having a vessel so closely sized to the system is like getting the BTU exactly right for a room, with no consideration of allowing better performance. 3. Installing a valve for checks (not a bad idea) is still an opportunity for an idiot to valve it off and create a system with no expansion...very dangerous...although I do see plenty of Instagram plumbers putting them in now because they are, lets face it, gods! Lastly I did check the expansion vessel and it was TOTALLY SHAGGED! Grant boilers have changed their MI to explain that their vessels only account for boiler expansion, since so many kept popping!
Not salty at all just pointing out a few things chap. If you are going to give tutorials on YT at least try and get close to good practice. You didn't even check the expansion vessel on the boiler, did you? You took the lazy option and fitted an oversized vessel that looked hideously ugly and out of place. Why did you feel the need to put a new vessel on the system? Your answer will be very revealing. I think I know why!!!
BTW 1.5 BAR is 50 feet/head. 1BAR is sufficient for most domestic houses unless it has several floors.
Coyote, That is a very good comment, I think you will find that there are a lot of so called plumbers out there who do not understand this.
There is a bracket for this. If you look for an expansion bracket. It come in different sizes. It is a right angle bracket that the bottom of the vessel sits on. Different sizes for different vessels. So simple and much more better. Can get them of eBay but like myself I made some before they came into existence for market. Now I buy them for £17 each . There you go. Fantastic work 😅
Im a general builder and worked in many many houses over the years and have only ever seen these a couple of times. Very rarely on combi/condensing systems.
Old school plumberparts video oh yes !!!
Regarding the thermolite blocks, I had a nightmare fitting my gun cabinet to them , then I found online Dewalt Gasbeton fixings. Drill a hole , screw them in and then use a coach bolt. Why don’t B&q or wickes stock them ????
Gixer750pilot now everyone knows you have guns at your house. 👍🏻
James Cole well you need to find where I live , get in , past the kids , the wife , the dog, me , find it, break into it . All whilst being recorded in 7 cameras that are uploaded direct to cloud . Good luck 😉

Mate in the near future the gov are planning phasing out conventional gas boilers etc can you cover some of the new alternatives such as air source systems or whatever will meet the new proposal plans for future proofing
That's only on new builds, no one wants an electric system they're useless.
Lol
Charlie agreed direct electric wouldn’t be my choice for anything other than heating the hot water with excess electric from pv. But air source and ground source may come more popular as well as community chp, as well as 5kw & 10kw heat exchange packs
James have a look at how Scuba-Pro secure diving tanks to the Boyancy Jackets. A big strap that just clips around in one go. So easy to remove for servicing as well BOOM job done!
Or look at doing something with Cargo Straps.
Another banger! Always a pleasure working for nice customers too, nothing more cringey than being the only one laughing at your own jokes in a strangers house :D
Compression fitting on the wet pipe would be easier?
True, but then people bitch about compressions...there's no way to win on the BATTLEFIELD THAT IS THE INTERNET COMMENTS SECTION! 😂 Tx for the comment tho!
Compression joints are for wimps
Should have put a lockshield valve to the expansion vessel . My biggest bugbare on expansion vessels as they need checking and refilling.
Classic style video - fab!! Do love the studio vids of course but also love this format in the 'real world' :) Cheers James and hope there will be more
Got one next week bro...and also a TWJ too!
Shona with her purple radiator with the very bad plumber! 😀
The expansion vessel from plumb centre is good. You screw the bracket to the wall. The vessel just hooks onto it and you tighten a screw from underneath and that's it.
Plumberparts & Times with James. It just don't get better than that.
Thanks man!
I was expecting the feed to be above the expansion vessel! With the feed to the bottom, how will the air that is in the “water side” of the vessel be replaced by water. i.e. how can you ever bleed the vessel? Does it matter? Thanks for all the helpful vids! Alan
There is no facility to bleed the hot water side of the vessel. This is because it is an expansion vessel for the water to expand into and not a water reservoir to keep the system topped up. The problem is usually too little air rather than too much. Excess air will just be lost into the system and vented or purged eventually. If your water has nowhere to expand, your system will explode (usually vented through the PRV for safety). So excess air in the expansion vessel on the heating side is never a problem. If all the radiators are below the boiler then it is a totally different story as the primary heat exchanger must never be allowed to run dry.
so i am about to fit 8lt expansion vessel above my airing cub'd on the 1st floor (off existing CH return pipe) the existing combi boiler is on ground floor, my question would be should I fit a bar pressure gauge to the vessel.
fitting the Ex Vessel is solely to help the boiler strain
I would really like a bit more I'm formation on the fittings on the expansion tank...
Currently 6 months into a plumbers course, no practical yet just books and more books, have you any advice or what are the basic tools i should buy first. Cheers love these been very insightful
Think I did a vid about it mate...search my channel if you get a mo!
Wowsers thank u was 6 1/2 mins long from 6 years ago lol most expensive 6 mins of my life thanks keep it up mate...
Why did you not use a compression tee james. Doh
IMI expansion vessels are brilliant should try them out and hanging them are a breeze
Will check them dude!
Definitely go with IMI expansion vessels. Worth going on their training. They have a app to size vessels. Also do balancing TRVs to get your DT to 20. Try downloading HyTools app.

👍🏿 I have a mini expansion arrestor which isn't working in my opinion. Can I drain the system and then replace the arrestor with a new one? Much easier than recharging, I think.
Why didn't you just not use a compression fitting?
We missed you!!
I'M BACK!
Some sort of rigid ring with a screw or latch fastener would be better than big jubilee clips. Like they use to join sections of twinwall flue
Just looking at your video I have a question for you when fitting a external expansion vessel to a combi boiler which as a magnaclean to you put the pipework about or below the magnaclean from the expansion vessel
Thanks for the vid.
Perhaps you could help explain more about your comments regarding expansion and the need to install extra expansion? I assume as part of planning a system install the amount of expansion is based on the boiler plus the number of rads. I would've thought most combi boilers would have recommended system design? It's only when extra rads are added would there be a problem. The internal expansion would no longer be able to cope with the extra water volume and would eventually compromise the air balloon. Is there an expansion calculation based on the volume of water in the system?
Hi Bry, a guy above mentioned it being 4% expansion so an 8 litre would easily do a 100 litre system...although I prefer to run my systems low and comfy - lots of expansion, low pump speeds and low(ish) boiler temps...each to their own though!
Great vid 👍
top work James fantastic installation enjoyed the video.
Always useful 👍👍👍👍🍺
Lovely job!
When you drain a system do you drain all the rads or do you turn them off and rebalance at the end? Do you save the liquid or throw it away and put in new inhibitor or whatever?
Omg she is very shy on camera. To be honest can you upload more like this working in domestic houses please. This video is a dreamy so please I would like to see how you manage and communicate with customers. You are great!
Next week mate...
Life saver if you've got an old combi with a dead expansion vessel and no access without re-fitting whole boiler
Can anyone tell me the best way to to connect a tundish from an unvented cylinder into a soil stack?
The cylinder is in a cupboard in the centre of the house. The soil stack also runs through the cupboard. So it makes sense to use that for the tundish. The alternative of running a pipe to the outside would be a v tricky job.
A hook would be best way to hang them. Similar to how you hang a radiator but wider
David West i agree. if there was a bracket on there and then just hang it like a rad
I'm not a plumber which will be clear from my question... can the expansion vessels be placed outside in an enclosure? We have an external Grant boiler and I noted that this installation does as well.
I use a 22mm outside tap back plate instead of the brackets, bang tidy
I have to ask how do you decide when you need an expansion extra vessel,Is it actually every time you fit a combi,I ask because there must be thousands of combi,s out there without the extra vessel,I fully understand why you need it , but it never seemed to be talked about years ago, So what exactly problems occur if you do not fit one straight away. Yes, i realize you busy bloke cheers anyway.
Great video James but no explanation why you are fitting another expansion vessel. Why do you need them in the first place? Please.
To take up expansion of the water. As the heating is on and the water within the CH system is getting hot, the water expands and these vessels help to absorb that expansion.
Portable expansions vessels have there own bracket incorporated into the vessel.
Locktite over PTFE? I tried the Locktite 577 that stuffs amazing it's just really expensive in comparison
Loctite but PTFE has it's uses!
Loctite 577 is awesome. And you can pick it up cheaper via eBay. I always use it on concealed showers. I had one leak 3 years ago and it wasn't good. So I always 577 the threads. Job done
Of course most threaded joints need ptfe and some 577, but 577 guarantees all joints. Why worry about cost per joint? Any redo will pay for the cost of the 577, traveling back to a repair - well that really puts its cost in perspective.
I have an undersink electric water heater 15 ltrs. Also fitted supplied water 4 litrs Zilmet Expansion vessel. In two years I’m on my third vessel keeps leaking from welded rim. Any solutions. Is it an easy task.
Are these fitted on the flow or return side of the pipe work?
Do you charge the new vessel or does it come allready charged ?
If you screwed screws into my thermalite blocks without using plugs you would be doing the job again, and replacing the blocks as well.
Even though you're French, I was able to understand
What is the expansion vesse pressure l with the water drain
Can it be t in either flow or return on heating
should of been a red expansion vessel for central heating
I always get the expansions with a bracket and they just hook on but then they have to always be vertical.
Dust sheets missing on the white goods
Flow or return for expansion
Get those yellow shorts from the missus?
Is the B&M rectangular bowl available in your shop too?
I'll see if Shona lets me grab it!
A good podcast while you work is Crime Junkie
I got my own plumbing business hate giving prices for jobs. What do you charge for that type of job .?
Also do you you charge mates lol
All hail the locktite 55
Why not red ?
Hi James
Hi mack
@@dillsplosion5334 Hi James and Mack... 😬
Does your shop do dustsheets?
Rick B b and q do them if you want some champ
Yaaaaaaaa
My plumber removed my expansion vessel 😳when he changed the cylinder.
didn't seam to happy when I dropped breaky at Stansted?
Laco flux never get leaks
James, if your teaching people to do the job right, first thing to start with is protecting the customers property. No dust sheets or protection on top of the washing machine. I know she’s a friend of yours but all your tools on the top could easily scratch or damage.
Where’s there a blame there’s a claim ,
Just saying, I enjoyed the vid. 👍
That looked like a lot of Loctite 55 haha
1:12 "whatevs, m8"
Great video James, thanks! If I had to remove the old vessel, how do I or what would I use to blank off the old connection so I make to fit a remote one?
Thanks
why would you need to remove the old one
@@cliveramsbotty6077 If the old vessel is passing water through the valve what other reasons would they need removed?
@@robertmcglone89 an external vessel would be fitted for additional expansion capacity. the internal vessel provides expansion vital to the boiler - if the old vessel is faulty then replace it.
@@cliveramsbotty6077 sorry I didn't word my first question correctly. I was wanting to know in the situation where the old vessel is leaking and to replace it would be awkward due to the likes of having to remove a flue etc. If I was to install an external expansion vessel and had to disconnect the old one what type of fitting would I use to cap/blank off the old connection so that it can not leak anymore.
@@robertmcglone89 You'd have a look at the expansion vessel and use whatever fitting you needed to cap it off. Forgive my assumption here but you don't sound like a registered gas safe engineer, best to get someone who is in to look at doing the job safely.
Tha vessel is FM (Fucking Massive)
Listen to the joe rogan experience he has a lot of good stuff on there especially with Elon musk 👍 great vid jimmy thanks mate 👍
Joe Rogan is essential. I too, can highly recommend. I haven't seen the Elon Musk one yet tho. Didn't he allegedly spark up a "doobie"? Everything from Alex Jones to Sam Harris and everything in between. Really, really interesting and thought provoking conversations.
@@loafersheffield yeah he sure did
@Marsbar 23 and they maintained a cogent conversation? Must have been really weak strain of weed. I like Sam Harris' podcasts. The Douglas Murray ones were "interesting". However, I have to exercise caution when listening to them on my job site radio, particularly in Rotherham with a certain type of customer may be ear-wigging in. You know the sort? Those who are ideologically dogmatic and easily offended.
@@loafersheffield he only took one hit wasnt a full joint. Very enlightening podcast if your into AI and the possible advancements in technology that could be made. Plus Elon is pretty chilled aswell
Chilled is a state of consciousness that is very much under-rated. Seems to me that it is when one is chilled, relaxed, that one can focus better. Seems to me that so many people get into petty, ferocious arguments over which brand of soldering flux to use. Laco or Powerflo? Surely there are more pressing issues to consider in one's lifetime. Hey-Ho! This Rogan podcast was good.
ua-cam.com/video/lGdPcC0zBIQ/v-deo.html
I've read a lot of Sam Harris' stuff and Maajid Nawaz's autobiography was.....Well, scary. I'll leave it at that.
I'd have covered the customers washing machine before using it as a work bench and scratching it up. Just saying.
Do your UA-cam viewers get a discounted rate? I need a Combi boiler installed from a regular system.
