Andrew Smith :

This would only matter if you had a one pipe system

Andrew Smith :

On a standard system if there was a blockage then it would circulate through the other radiators instead

Andrew Smith :

Depending on the model of the boiler there may be a filter on the flow or return valves at the boiler - did they check after flushing if they are there and if they are clean?
