Reducing corrosion and lime deposits caused by water impurities on surfaces exposed to water is performed by the presence of magnetically treated water. It is found that the reduction of corrosion or encrustation is much more effective if water from a magnetically treatment unit (1) is passed over the affected surfaces to flush them as directly as practically possible and at as high a flow speed of practically possible. Water that has been used to flush these surfaces is recycled through the magnetic treatment apparatus (1) by means of a pump (8) and used to flush the affected surface again.

Why it's free to use
- Filed March 17, 1992 and granted May 28, 2002. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended March 17, 2012.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by March 17, 2014.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
