Close couple the vent and cold feed, done it more times than I can remember over the years, stops the open vent then sucking in air.

Good tip, with the H couple tip. They need a new boiler though so should see them through until then

Great easy to follow video, my air separator is an old grey one with 4 pipes attached, im guessing cold feed, vent to F&E, one to the pump and one to the boiler? Radiators have no water getting to them or air when bleeding, so im guessing its blocked, if i were to cut the Air separator can i just clean it then connect the pipes back with compression connectors? as i cant seem to find a 4 way one like mine. Thanks

Repipe the feed and expansion possibly combine the two and pipe them in before the pump also increce hight of header tank for larger head of water and doesn't help with those boilers as you can't have a pump overrun

Air separator! Welcome back to 1980… coulda just flipped the pump back around correctly & did a combined feed & exp set up… fitting Aladdin vents is just gonna hide any air that re-occurs :/

Would an Automatic by pass be needed on the system?
@jonnyallen1232
@jonnyallen1232 7 ай бұрын
Auto bypass only needed on s-plan , if the two valves shut off the water can still pump through the bypass, y-plan systems close in mid position so don’t require a bypass

Could you have just pressurised the heating system ?

Yes, I suggested it they've spent load in other engineers. They wanted it fixed asap as it's an Airbnb HMO so Toolstation was open they had these and boom done same day.

I am guessing you are not allowed to put a Check Valve on the Expansion Valve (TSP as we call them) outlet?

No we're not, it's a safety device so anythin potentially blocking it isn't allowed

Cut out the stupid air separator. Make what’s called a. H. Open vent to f and e. Then cold feed from tank has pump on it. Drawing down from tank. Always leave pump on speed 2. And don’t forget some fitters don’t fit open vent high enough. And the two pipes on the H. closer than 6 inches

That's the worst solution ever ,air separators tend to not separate anything when time passes by just pure blockage better fit automatic airvents remove that air separator please

I did fit aavs 😅 They block after many years. Hence why I magnacleanse flushed it, I will now maintain it, it 100% won't block. They need a new system anyways. They'll get a new system when time is right.

@@mendyourhome 100% agreed and if it's to a proper combi even better (well depending on how many radiators) if not system or sealed then will be spot on and please no gravity they just so outdated 👍
