Hi guys, me again, I thought the problem was solved but sadly not. The
electric part of the valve seems to be working ok now, with the little
lever moving up or down accordingly, but the radiators are still
heating up both when I put it on water only, or radiators only, does
this mean the valve will need replacing, and should I put flushing
additive in first or after replacing valve, and then inhibiter? [no
inhibitor was added by fitter] thanks Richard.
