    Hi All

    I have a Heatrae Sadia unvented cylinder... with the usual PVR on the side... which discharges to a tundish which is then connected to a 'fanny trap'.

    The problem -
    Water trickles through the tundish after about an hour or so of the hot water being heated and the pressure rises. It's only a trickle. To stop this - I have followed the instructions to re-charge the air at the top of the tank. This goes fine - as per instructions. Once air in tank is reset - the tundish trickle stops. Give it about 6 weeks... and its back.

    Is this normal - should I have to re-charge the air bubble in the tank every 6 to 8 weeks ?

    Thanks,

    Tim

    You need a G3 qualified engineer to work on it my friend. I’m guessing you are not one

    Thanks Riley - yep I know that - and correct I am not one - and I have no intention of working on it.

    In which case my friend you will need to enlist one as what you describe isn’t right

    Looks like your cylinder has developed a fault which might be permanent and can only be sorted by a new cylinder which would be too costly, or a different fix which a G3 plumber would hopefully recommend.
    Either way, you need to get a qualified person to do the work.
    Cannot say more than that obviously.

    Thanks Best. I assumed there must some 'bigger' issue - as I just cant see its normal to have to keep re-charging the air in cylinder. My local plumbing firm have had countless attempt to 'solve' it - and £hundreds later I am still left with the problem. Thanks again.

    Thanks Riley - yep - thanks for confirming what I feared. The problem is (and the reason I am on this forum) is that I have enlisted a G3 firm already - and seem to be getting nowhere :-(

    tbh i would get the g3 engy to fit a new part and do away with the internal bubble as there too much hassle
