I intend to powerflush my central heating system prior to a plumber installing a new combi boiler. I will be hiring the kit from HSS. I am happy following the instructions apart from one thing. If I connect the appliance in place of a radiator, do I have to take any action to disable the pump in the boiler? It is an old Ocean Stylee FF boiler if that is of consequence. I am not concerned about any damage to the boiler in its capacity to provide CH but I need to preserve its HW functionality for a couple more weeks. Had a look at the pump in the boiler but no obvious way to disable it. Many Thanks Paul
