    Cant believe i read most of that.

    In short you have a circulation issue. You could try a sludge remover but if there isnt any circulation its effectiveness is limited. It would be worth trying the pump to see if it makes a difference 1st.

    Otherwise a decent flush is probably a good idea.

    Thanks petit-pablo. Srry about your eyesight though - bet you look like this now :eek:

    I will have a ring round to see the cost of getting a new pump fitted. How much do you think that job would cost if i supplied the new pump (an exact copy of the old one)?

    I tried to anticpate what questions would be asked when I provided the details of the problem - ergo the long post. I thought this might be better than batting back/forward of questions and answers. Thanks anyway :oops:

    I assume your radiators are properly balanced (i.e. via the lockshield valve on each radiators)?

    Thanks for the reply chudley -

    Anyway - the radiators lock shields have not been touched since installation (they were balanced then).

    Is balancing an ongoing thing?

    The balance settings will change as the rads become differentially sludged up.

    However the solution is to clear the sludge and not to rebalance.

    Thanks Agile, thanks.

    Can I ask one more thing of you? I inserted a screwdriver gently into the pump when it was on, at the centre screw hole and I felt a ratcheting - as if the tip of the screwdriver was grating against spinning cog teeth. Does this mean the pump is definitely working and at least trying to pump?
