How does a Power Flush work?
 
The CLEARFLOW power flushing pump is simply connected into the heating system, either across the standard circulator pump couplings, acrosss the tails of one radiator, or wherever most practicable.
 
Power flushing is a highly effective cleansing operation which works by pumping water at a much higher velocity than usual through the heating system, to loosen and mobilise harmful corrosion deposits and to suspend them in the rapidly moving water.  The process is made more effective by specialist cleansing chemicals and an instantaneous flow reversal device, which creates turbulence in the radiators to optimise 'pick up' of the debris.
 
Once loosened, the unwanted debris is purged from the system with clean water.  At the end of the flushing process, the system contains fresh clean water, and reinstatement of the system to normal operation takes on a few minutes.
 
During the CLEARFLOW process, radiators are individually flushed, without remoing or disconnecting them from the system, by directing the full output of the pump through each radiator separately.
 
CLEARFLOW power flushing is not a high pressure operation and it is suitable for most domestic wet central heating systems.  It is carried out with minimal disturbance and disruption to the normal operation of the system, often without disconnecring the boiler or any radiators.
