    Hello,

    After bleeding the radiators at the weekend my boiler pressure was low this morning (F1 code appeared) After a little bit of research a increased the pressure, admittedly I may have done it a too much as when the heating is on the bar is 2.5.

    My first question is have I closed the valves properly please?

    Secondly to bring the pressure down a bit, I've bled the radiators again but the pressure is not budging. It took 4 days to come down when I bled them at the weekend, anybody know why is it taking a while to decrease please?

    Thanks in advance, I appreciate it.

    The valves look shut, and if the pressure is now stable, I.e not rising that proves it.
    Continue bleeding at your radiators and the pressure will come down but you may have to lose a litre or so.

    It wouldn't take 4 days for pressure to drop when bleeding radiators.
    I suspect you have another issue ,possibly the EV. What is system pressure when central heating is on ,and what does it drop to ,if viewed a few hours after heatings been off ?

    Thank you for responding.

    Do you a mean a litre total or from each radiator please? Also, the pressure has now dropped to 2 bar and my heating is on so hopefully it should be a bit more normal when I turn the heating off. I'll update this thread when it's been off a few hours.

    Thank you again :)

    In hindsight, you probably meant a litre altogether, apologies for my dimness!

    Once cool, I turned it off and did what Burnerman/John suggested, the first is after I bled the radiators, the second is when I put the heating back on.

    All looks good to me, do you agree?
