    Hi There

    I have a potterton system boiler. I bled a rad and now have no pressure, can anyone tell me where I attach the filling loop hose

    The two pipes under the boiler with the plastic valves on them have been capped are different sizes - is this unusual ?

    There is a third capped pipe connected also but this doesnot have a plastic valve - which two do i connect to ?

    Your filling loop will be else where, cupboard underneath boiler, cylinder cuboard, under sink or is some of the piping boarded in ?
    The 2 valves at each side are heating flow & return. The filling loop requires a cold water pipe to link to a heating pipe.

    Ok - the plumber was here -

    He said there is no filling loop- that the boiler is gravity fed - he will fit one tomorrow - nothing that he can do tonight, so another night of freezing my knackers off.

    Seems to me there must be a way of getting water in - or how was it filled when installed ?

    Any ideas anyone ?

    take a look in your attic, for some reason some people/installers connect up the filling loop on the old cistern fed part of the system and they get calledback to fill it when the pressure drops as the owners cant find a filling point! found 2 like that last year.

    Checked the attic, just straight pipes to the tank - the house is only 6 years old, everything about it was cheaply built - there wasnt even any insulation in the pipes up there, there is a gale blowing through the windows etc etc.
