I don't believe any water is leaking anywhere. She had the combi fitted
when she qualified for a Government grant and from what she tells me
(A) the system was never bled in the first place as the fitters told
her that it "bled itself automatically" and (B) the rads have never
worked at proper temperature since the combi was fitted. A lot of
'effing and blinding from the lads who fitted it but no aftercare.She
was never told about the filling loop and she now tells me that the
instructions suggest regular checking of the pressure and how to top up
the system using the filling loop. I think it's a fine system (it cost
her nowt) but it just needs bleeding. Everytime I bled it I knew
nothing about refilling the system using the filling loop. To
recap,tomorrow when I bleed it, should I bleed it with the system on
then? - and fill the system accordingly. mr J
