A friend is having trouble getting his downstairs radiators hot. (Upstairs

A plmber has replaced the pump to no avail. Today he did a power flush but
he connected to a radiator flow and return. I had assumed that flushing was
normally done at the pump connectors.

If there is a blockage then I believe the pipes under the floor are the
problem.

Sould he be trying to connect the power flush into one radiator - and the
return into a different radiator?

So long as you isolate the various parts of the system so that you are
flushing each individual bit in sequence, it should not really matter.
The procedure is described he
