This simple video has explained so much to a numpty like me. I have a similar device on our system which was installed probably 30 years ago and I have no idea what it was, neither did the so called plumber who has just changed two radiators and now left me without hot water or heat because the system will not refill, and its -3 outside today. Thank you so much for the explanation, not at least I can try and check the feed from the header tank myself. Cheers
Your vids are really helpful and informative I'm currently in college doing my second year on plumbing and it's great to see your vids to help with more information and expand my knowledge in the trade
Ideal used to have a diagram of one of these in the boiler instructions. It was to have the F&E tank located just above the boiler. Without one you need the F&E quite a way above them. It will work with any vented boiler. I used one as combined heat & vent pipe - that is a 22mm pipe off the top into the bottom of the F&E tank - the boiler needs a high level temperature cut out, which most have these days.
Note: The "expansion pipe" is the pipe coming from the expansion tank that feeds the system, nearly all water being pushed out of a system by expansion flows up this pipe, it does not flow up the pipe that vents air out of the system, this pipe is Known as the "vent pipe".
I had my aerator removed.... clogged up and stopped the water from moving altogether. My plumber fitted a piped H section instead with a small air release valve built in. Works a treat & my rads are hotter than they've been for years...
They fitted a H shaped section out of 22mm pipe & put the small air release valve in the middle of the H with a 16mm pipe. A fill valve at the top right hand pipe & an air release pipe to the top left both of which were already part of set up. Works an absolute treat, the rads get so hot its unreal & the new pump I fitted is set on the lowest of 7 settings.
May be better to put pump further away from vent pipe? I'm just trying to work out why the pump would rather suck water when it has the option of sucking air through the vent
It's circulating the water. The water coming up behind the pump is being pushed by the pump also, so its not just getting sucked. The water level in the vent pipe will drop slightly but not much. I hope that makes sense. Also, these are vents are stupid, just use a T.
Do I NEED a de-aerator, something like a Spirovent RV2, on my Combi Boiler..? Having a new ATAG on an old system. 12 Rads.. (After a good flush of course!) Is there anything similar to the RV2 but cheaper? It’s nearly a £100..!! Thankyou!
Hi James,I have a question or two if you don`t mind answering please, I am building a copper air condensing tubing system on a wall to be used from my 160 psi air compressor.I will be using a flexi rubber compressor air hose in between the compressor to the copper pipe system to have no vibration between the two.the idea is to condense the hot air that the compressor produces and traveling through the copper pipe it will condense to cold air at the end, Then I will use a catch pipe to drain of the water so it does not enter my tool. My questions are, Question 1) Do we have a lettering system K-L-AND M on our copper pipe like America do to illustrate the different thickness off the copper pipe wall, Question 2)If we do Have a system over here what is the system we go by. Question 3) would I braise it or solder it,I know that Braising will anneal the copper and make it softer near the braised joint,would this cause a problem to the coppers psi strength I will want to use 28mm and place a reducer to drop the psi to 125 for the tools I use,
Just had a new pump fitted, since then when the pump is on speed 2 or 1 water is pushed back up the vent into the header tank. Would this be a blocked air vent. When I put the new pump on auto which reduces the speed it doesn't do it.
Hurry up with the shower tray install vid!!!!!! Got the plasterer coming Friday, and so after that, I can get on with installing the bathroom - FINALLY!!!!!!!!!!
Can’t believe how difficult it is to find a vid showing how to replace a air flow valve right on the damn furnace system! Mine is leaking, already bled the bloody lines but need to replace the valve. Damn it there is nothing on line how to actually do the job!
Great video James! Would be great to get back to more instruction videos. Perhaps you can get your network of plumbers to help out? You can't do it all, or can you? Lol 😁 👍
After looking back at my level 2 course the 150mm is called the neutral point which prevents corrosion in the system as the pump causes a see-sawing motion aerating the water
Get Bry Yes the neutral point is where the cold feed joins the circuit. The water will be under negative pressure from the cold feed to the pump and after the pump it is under positive pressure. Provided there is sufficient height or capacity in the vent pipe it will not pump over into the expansion tank. Thank goodness most new systems are sealed so these problems don't occur so much.
Sorry, but it's not true that inhibitor stops "air" from forming in the system. Inhibitor slows the process down. Hot water in the pipework reacts with the copper to form hydrogen gas. One or more auto vents will be needed to let the gas out, otherwise rads, almost always at the highest point of the system, will need "bleeding" quite often. If the boiler is a combi, installed higher than the rads, the built in auto vent should keep the system free of gas.
James's clearly an expert so the burden of proof lies with U to prove that U're right. Is there a book or regulation that says it's called 'the safety vent'?

Could you explain the need and position for fitting an air admittance valve. Cheers

what stops the pump from sucking air down the air vent pipe?
It's not usually a problem, but altering pump position, speed and crook height all have factors in improving it.
May be better to put pump further away from vent pipe? I'm just trying to work out why the pump would rather suck water when it has the option of sucking air through the vent
It's circulating the water. The water coming up behind the pump is being pushed by the pump also, so its not just getting sucked. The water level in the vent pipe will drop slightly but not much. I hope that makes sense. Also, these are vents are stupid, just use a T.
denis moloney Thanks for explaining. vent in 22mm pipe?
yeah
What if the air separator is blocked?
Do I NEED a de-aerator, something like a Spirovent RV2, on my Combi Boiler..?

Great Video De Airation 😅
I Prefere the word Air Divider 👍
Or Tower Air separator 👍
Hurry up with the shower tray install vid!!!!!! Got the plasterer coming Friday, and so after that, I can get on with installing the bathroom - FINALLY!!!!!!!!!!
Goldfinger have a look on ultimate handyman he has a good video on shower tray.
LIES! :)
plumberparts new it wouldn't be long till you comment 😂😂
Can you put it on sealed sytem with auto ven when you have octopus effect legs
Very interesting! Looking forward to the next videos (here we only have pressurized systems).
Cheers Koffi! 😎
If you removed one would you just connect the pipes up and stick an auto air vent there? Obviously keeping the vent open.
very helpful. Could you tell me where I can get this fitting, please?

How can you fix a whistling TRV? It's driving me nuts.
Replace it mate, or reduce the pump speed....might help!
plumberparts thx mate.
If u can't beat it, join it.
Have u tried beating it?
James the man
Cheers dude!
always wondered what it was

Dont Get by Get Bry ha! Cheers mate. And of course I can!
plumberparts I seem to recall theres a 150mm rule around why the vessel is designed the way it is.
After looking back at my level 2 course the 150mm is called the neutral point which prevents corrosion in the system as the pump causes a see-sawing motion aerating the water
Also probably to do with the magnetic field of the pump....but you never know!
Get Bry
Yes the neutral point is where the cold feed joins the circuit. The water will be under negative pressure from the cold feed to the pump and after the pump it is under positive pressure. Provided there is sufficient height or capacity in the vent pipe it will not pump over into the expansion tank. Thank goodness most new systems are sealed so these problems don't occur so much.
Hold tight
James u r a very excellent man.

YAY!
ugh I hate when I have to back blast my sludge and poo
hahahahhaha tarquin!
Stop calling the vent the expansion :)
It's an old habit.....but it's really Vent AND Expansion.....
***** No,it's actually just the safety vent.The expansion takes place in the feed from the tank, hence the term feed and expansion tank.:)
James's clearly an expert so the burden of proof lies with U to prove that U're right. Is there a book or regulation that says it's called 'the safety vent'?
