Looked at a Y plan system and this failed the magnet test to the top front connection - do they unblock easy in place?  |

Not an expert on the Aerjec air seperator bean cans, but in my limited experience it's chop out and either replace or redo the pipework in line with more modern thinking. These things are known to be a blockage point especially on systems where the owners have been less than scrupulous with cleaning and inhibitor.

Cut it out matey, they’re the Neutral point we n the system & block up easily.

So are we saying best practice is cut out the old aerator (I believe it's a Myson) and fit another new aerator in its place or just pipe up to suit the circuit demands?

I'd put a new air seperator in it's place battle. Early low head fully pumped systems had big problems with air getting sucked into them and then pumping over and these A/S did cure this problem. The modern fix for this is to convert it to a sealed pressurised system by fixing an expansion vessel and removing the expansion feed tank altogether. However, I'd keep it simple in this case (after all, I'm only a simpleton plumber  ) |

bear in mind battle, If its an old system, It might cause problems with an old joint or two or, an old radiator, warn your customer of that if you go the pressurized method,  |

I’d rip it out, close couple the F&E before the circulation pump on the Flow.

It's always good to get a number of different ways of doing a job battle then you can assess them all and then use whichever you reckon is going to be the best option.
It all looks very tight in that airing cupboard though.
Let us know how it goes.

It's the floor in the shower/bathroom it's white and cost them a fortune and I know there will be plenty BLACK SLUDGE so it will be easily marked in that awkward location as you wriggle to get in and out. Let's see what they say about what I've told them I need to do. I do like other people's thoughts and opinions before not after the event that's why I like to ask! |

Almost a through the years of central heating history guide that one Dick...very interesting. When I was at collage we had to draw the cold feed connecting to the central heating in the neutral zone between pump and boiler  . Whilst at work we would always connect it into the primaries gravity return in the cylinder cupboard - indeed a neutral zone in any system  . It was all gravity primaries in those days . NB Onto the 80s and fully pumped systems I've often seen expansion tanks rammed right up to the apex of the roof in bungalows because of pumping over issues! |

Yeah, when I started my time in the early 70’s there was still a lot of Solid Fuel CH being installed, 28mm Gravity HW F&R, all formed bends. F&E at the cylinder coil👍 Fitted my first Gas Combi in about 81/82. |
