Power flushing is the fastest and most effective means of cleansing sludge and corrosion debris from central heating systems, utilising a high flow of water to loosen and ultimately expel the debris, usually containing large quantities of black iron oxide, from the system.
Clear water is forced through a system, pushing debris ahead of it, and this continues until the dump water finally runs clear. This may take a considerable time.
The rapid removal of debris from the flushing water prevents saturation of the chemical cleaning solution with black sludge, leading to a more effective power flush.
The debris retained on the magnet is an impressive visual aid, and clearly demonstrates to householders what has been removed from the system, confirming the need for the power flush, and demonstrating that the clean has been professionally carried out.
The objective is to restore systems with circulation and boiler noise problems (caused by sludge and corrosion deposits) to optimum operation. Power flushing removes these deposits and the problems that they cause.
