How does a powerflush work ?

A central heating flush or powerflush works by circulating chemicals through your heating system to dislodge any internal rust and corrosion that has build up and settled in the pipes and radiators.

The powerflush machine and attached magnetic filter, which collects the dislodged black sludge, are connected in the place of the circulatory pump. The chemicals are then pushed into the heating system to dislodge the build up followed by a cleaning solution to flush the system. Finally, neutralising crystals are passed through the system to balance the pH levels.

The process is repeated until the water runs clear and the pH levels are balanced. Read More about how a powerflush is carried out.
