    Sorry again it was actually 6th pic down where it appears that the fill into your system is connected to a plumbing pipe ,permanently connected and relying on a swing non return valve to stop backflow.This is wrong on so many levels. Regs or no regs.

    Why? What could happen and why do you think it was done in the first place?

    A pressurised or sealed heating system is normally filled from the mains using a temporary flexble connection (connect to fill-remove when finished). Thewater also passes through a double check valve to ensure that no heating system water can backflow into the main.This is standard water regulation.
    Yours on the other hand appears to be connected into your cold supply to your bathroom cold taps .toilet,showers etc.
    The strange bit is, you say your heating system is at 1 bar. Is this hot or cold pressure reading?

    Sorry, I was wrong about the system water pressure! I brought up the fault code log! When i try to bring up the pressure throgh the diagnostic menu it skips over the no. for the water pressure. It says the pressure is shown permanently when the system is off but I think ours is in stand by on account of the motorised valves. So can you tell me how to get the water pressure?

    Sorry I do not work on gas boilers so can't help there I'm afraid. Under normal circumstances topping up a sealed system is a simple procedure but in this case I am looking at pipe arrangements that I do not recognise. Maybe some of the gas lads on here can help you. If its any consolation I still do not think that your problem is a leak.

    I have also downloaded the installation manual for this boiler and of the three suggested methods of filling the system none is remotely like yours I'm afraid

    Can you think of any reason that none of the lads on here are willing to help you? Strange I must say.

    Mostly it is OK, but that fill pipe , if that is what it is. just doesn't look right.

    I imagine that most had thought you had it all covered and as its now gone 3 pages and been made a tad confusing most just can't be asked to catch up on it.

    :eek:

    A wee bit more info OP. What you seem to have is an ATTEMPT at a semi sealed system. Seems to be recommended by some gas boiler manufacturers. Although a dedicated top up tank should be installed.What you have is a shortcut.The bare minimum pressure to keep the boiler satisfied,yet not enough to annoy any existing dodgy fittings.In other words OP the LAZY way out.I take it from the silence on here that this is common practice. And then they cry about regulations and unregistered workmen. Hard to beat a bit of experience.:D

    The fill valve on the system is a 1/2 inch 367 valve. If it is hooked up to the mains 10 times out of 10 these valves will pass when closed on mains pressure. Are you sure it's connected to the mains? Flexicoms can be configured to work on low pressure systems.
    You could follow the 1/2inch pipe into the attic and see where it terminates.

    First I would get that set up changed for a proper filling loop. Then see if the pressure drops.

    Then I would get the coil on the cylinder capped to see if the coil has a pin hole in it.

    Also has your RGI checked the boiler expansion vessel and safety valve? The valve should be piped to the outside and should be 1/2inch copper. It will be outside in the location of the boiler.
