Power flushing what is it ?
The expression 'powerflush', used throughout the plumbing and heating trade to denote the process where heating systems are cleaned by passing a mixture of water and chemical cleaners through the pipework and radiators at high velocity and low pressure, mobilising sludge, scale, rust and other loose debris that can accumulate in the system and boiler heat exchanger, causing noisy operation, reduced efficiency ( resulting in higher fuel bills ) and sometimes complete failure of the boiler.
How does it work ?
The powerflush pump is connected either via the pump connections or across a set of radiator tails.
Powerful cleaning and mobilising chemicals are then added and the pump is run. the powerful flow and flow reversal will dislodge any sludge and corrosion that would not be removed be more traditional methods.
Each radiator, the boiler and cylinder ( where fitted ) are then individually power flushed ensuring all of the system receives a comprehensive clean.
A neutralizing agent is then added to make it safe to flush with clean water and dump the existing contents to waist.
Finally a scale and corrosion inhibitor ( BS7593 ) is added to ensure prolonged protection of the entire system.
The pump is removed and the system returned to normal operation.
