the reason the F&E is so low is because the house is a maisonette, meaning there is no loft/attic, its a flat roofed house, I used the vent to pressurize the system because thats the easiest way in that sitation, It worked in filling up the upstairs rads, the tank is just a couple of inches higher so gravity from the tank in 15mm will struggle, My next move on Monday is to pressurize the cold feed coming from the F&E, the feed from the tank is direct to the boiler bottom tapping, If that don't work, its head scratching time,  its a basic heating with no controls from a glowworm free standing boiler, installed about the 80's View AttachmentI’ve seen expansion vessels out on the vent to make a heating system pressurised. Is the vessel all that is needed? How about a prv? How will you pressurise the cold feed please Tom? Rct |

Is it worth pressurising the system tom...would the rads / system take it ..?

thats the $64,000 question Dr B , a weak joint or worn out radiator or even a pin hole in the copperwork could show up, Its a game of Russian roulette and we're hopeing for the empty chamber when we pressurise old systems, But with the low head and plenty of gundge in the pipes its a 'do or die' situation, Rocky, I've teed a 15mm live mains in and pressured from the vent, I now intend to used that live mains to pressurise the cold feed from the F&E, that goes directly to the boiler bottom connection, That should push the water all the way from the bottom, Like PB suggested earlier, IT will fill from the bottom and hopefully push the air out of the vent, fingers crossed,  |

Just a quick check tom. I'm taking it that that lower pipe is the central heating flow up from the boiler and the pump is on the CH flow. Or is it that the higher pipe is the return going to the boiler and the pump is fitted on the return? Nothing wrong in checking the basics  . I agree pressurising could give the old gal a host of extra problems. I wonder what would BG do here?  ? £££££ !!!! |

Not that I know much or could educate you on plumbing Tom but this is what I use on my problematic system full of sludge job. Although mine is a hoselock version with five ports. www.ebay.co.uk/itm/4-WAY-TAP-ADAPTER-VALVE-SHUT-OFF-MANIFOLD-GARDEN-HOSE-PIPE-CONNECTOR-SPLIT-70309/131770658048?epid=2254310213&hash=item1eae24ad00:g:SlIAAOSwbwlXAUCvIt's a garden hose manifold which I conected at various places and allows sensible control on the mains pressure and monitoring of the filling and flushing. The last time I used it this was how I got a result, to allow ejecting of the air and crap out of the system. I removed the radiator in the utility room - which also had the boiler in it, then I connected into the flow and return points from where the radiator was removed. I also used the utility room for the mains water in connection to the manifold. The flow on top of the boiler connection had a drain point so I connected on to that point again to the manifold. Finally, I connected to the 22mm vent, bring the hose downstairs to he utility room. Next I fitted a iso valve into the line to close off the normal F&E route to the boiler. Basically this allowed me to know I could flush the boiler and rads in any order and watch the sludge and air being ejected out of the system, flush the boiler it self and fill upstairs from the boiler drain point. It involved only one long length of hose the rest all short with the vent end back to the utility room sink. The vent allowed monitoring of the air being displaced and the closed valve on the normal F&E feed to the boiler stopped the the F&E tank back filling the tank to have stop an uncontrolled over flow situation. |

That's it tom positive attitude on a new day. I've seen expansion tanks only 6" above the CH pipes and they've worked (somehow), the pump on the flow is said to be better for radiators on drops so that's another positive. Drives you up the wall this plumbing malarkey  |

yea tappy, I assumed the feed from the F&E was going direct to the boiler, So when i pressurized it and it did;t flow I knew I was wrong about that, so i had to take boards up and found the cylinder return was teed in, a very strange piping arrangement, And I did't get it working yet cos the lady was going out, So I'm going back yet again Friday,
I'm making this my very last job, keeps going through my mind,, But when i got home the phones never stopped today and i've booked more work in, The addiction of work is harder to stop than drugs or alcohol,,, smiley-sad056 nay

For a short while it was the done thing to put a loop in the cold feed and tee it in to the system from underneath - never done that myself, however, I have come across it done a few times (what a mad idea that one was)!
It's always difficult saying No and it's not because of the money.
In an odd way (which I'll never admit) I think that we sometimes enjoy it when we are put to the test!
