How we power flush your system

what is power flushing?Hard flushing, jet flushing and power flushing are all terms used to describe the process by which central heating systems are forcefully cleaned by cold water at high velocity but at low pressure. The water is pumped at a higher velocity than your usual system would achieve as a power flush needs to remove very stubborn particles that require a hugh velocity to remove. The power flush is also performed at low pressure levels to ensure that no physical damage is caused to the system and makes power flushing possible on virtually any system. This process is also made more effective by the introduction of powerful cleaning agents.

 

One of the main objective of a power flush is to restore the correct circulation and flow rates that may have been reduced over time and also remedy some unusual boiler noises - both caused by excess sludge and deposit build up. Power flushing also features a prime purpose when installing a new boiler as it removes flux and other debris that may have been left over after installation

How it works

 

how power flushing worksThe power flushing equipment is connected to the flow and return pipework where a speed flow generated by the equipment, together with its quick reverse capability, will dislodge and flush deposits and corrosion through the machines full-flow drain whilst, at the same time, filling the system with fresh water from a hard connection via your water main. These high velocity, low pressure bursts of water will remove and breakdown a lot of the larger debris and sludge which was previously causing problems to your system.

 

A chemical is then combined with fresh water to loosen and suspend any further finer deposits, each radiator will then in turn be cleaned to remove these deposits. Therefore the initial surge of water will help to remove the larger deposits with the chemical further assisting to remove finer sludge and deposits from the system.

How we power flush

 

Before we start any power flush we firstly make sure and agree that the system is indeed in need of a powerflush (if prescribed by others). With authorisation from you we start some checks of the system, we check the overall condition of the pipework, boiler and radiators. If there are any problems found that would hamper a power flush being achieved, these would need to be address before the power flush can commence. We will then set up the power flushing equipment and make the appropriate connections and also make sure that all radiator valves are fully opened. We will then follow the below procedures:

  • Remove pump and isolate expansion tank (if applicable)
  • Initial flush of system (as outlined above)
  • Add deposit remover chemical
  • Circulate chemical around system
  • Close off all radiators except one and circulate through
  • Dislodge deposits by regularly reversing chemical flow to each radiator
  • Repeat above two steps for each radiator
  • Dispose of deposit waste via machine
  • Connect mains supply to radiator flush circuits
  • Dump flushed water to waste via power flush machine until clear
  • Remove power flush machine and reinstate pump and expansion tank (if applicable)
  • Add inhibitor to system and balance system where necessary

After we have achieved the power flush and your system is cleaned and restored back to optimum a system inhibitor is also added. The inhibitor provides a chemical prevention against the sludge and deposits appearing again for a very long time. This safe guards your system for years to come and ensures that your power flush has been worthwhile investment.
