Power Flush

The Power Flush Process

Our specialist team uses a custom power-flushing centrifugal pump with heaters, magnetic filters, rad hammers and thermal imaging cameras to provide a comprehensive and more efficient flush. We use techniques and procedures developed over two decades.

For health and safety, our gas engineer will carry out a survey on your central heating system on the morning of arrival and set up a workstation. There are five steps to the power flushing process:

• Procedure 1 – Dump – We pump clean water at 150 litres a minute through the heating system to push out all the mobilised iron oxide, scale and sludge from the heating system.
• Procedure 2 – Clean -We add chemicals to the clean heated water to enhance the chemical reaction within the heating system. This circulates through the radiators via flow and return pipes creating a wash motion. This is done individually and methodically throughout the system.
• Procedure 3 – Neutralise. Here, we repeat procedure 1 by dumping the non-acidic chemical water from the heating system and circulate clean water in the heating system with neutralising crystals to balance the PH Levels.
• Procedure 4 – Dump. Repeated with specialist techniques.
• Procedure 5 – Add inhibitor to a pressurised system, bleed and balance.
