I am also registered as part of the approved contractor scheme run by the water regulation advisory service (WRAS) contact them for more information www.wras.co.uk or telephone WRAS (01495) 248454.


A leaflet by the WRAS is available for download. The approved contractor scheme is supported by all water authorities in the UK and allow the contractor to self certify their work (without notifying the local water authority such as South West Water) and take full responsibility for their work. Contact South West Water for further information. We would direct you to these links to answer any questions you may have on the Regulations and what work requires water board notification and how they affect you.

POWER FLUSHING

Power flushing is the most efficient and effective method of cleansing a central heating system. The principle is to create a powerful fresh water flow under controlled conditions to remove debris from the system. By connecting the power flushing unit to the heating circuit in place of the system pump, boiler or radiator the circuit can be thoroughly cleansed of limescale and corrosion debris.

  • Blockage in radiator valve Leading to incorrect operation of valve, no flow in radiator
  • Pump seizure and failure The abrasive and magnetic properties of black oxide sludge
    increase shaft and bearing wear in pumps causing them to stick or fail.
  • Cold spots The familiar cool low central area of a radiator indicates a build-up of black sludge sediment that restricts flow and reduces heat.
  • When the top of a radiator is cold during operation, either air or hydrogen is to blame.
  • Hydrogen gas builds up as a by-product of electrolytic corrosion and is flammable (due caution is required).
  • Pinhole leak Water damage.
  • Black sludge in underfloor pipework Reduced flow or blockage in pipework.
  • Scale (limescale/iron oxides) in boiler Leading to reduced efficiency, increased emissions, higher fuel bills and boiler noise.

When used in conjunction with a chemical system cleanser, a typical power flush can be completed in a day.
