Rinnai - South Australia

Two Rinnai water heaters had come for servicing from very hard water areas of South Australia . The heat exchangers were heavily scaled with Calcium buildup and needed replacing.

We fitted the CALCLEAR Pre wound pipe, filled the scaled up heater with CALCLEAR treated water and left it to sit over the weekend. On Monday we fired up the heaters, fitted a stocking over the outlet and turned on the tap. CALCLEAR treated water passed through the scaled up heater, the scale was dislodged and shot out into the stocking filter thus removing the buildup on the heat exchangers.

The outcome was that the heat exchangers were cleaned up and didn’t need replacing.

Bolier Scale Removal - Bunbury, WA

Phil Best in Bunbury who is the President of the Master Plumbers Association was very impressed with the CACLEAR he put on. After a few weeks the boiler showed a great reduction in scale build up. Normally he had to remove 5 wheelbarrows of scale from this abattoir boiler.

Post Script – 2006 Yearly Boiler inspection showed no scale – opened it up , had a look and closed it again !!!

Chem Quip Services - Broken Hill, NSW

G'day Robbie,

Perhaps the following may be of assistance.


Whilst many areas of Australia have lived with hard water, increasing levels of Sodium are becoming our greatest concern, particularly the matter of corrosion in metal heating tanks including Stainless Steel. How can CALCLEAR assist in such situations?

It is quite correct that hard water has, for many years simply been accepted as part of life, Adelaide is a classic example, surprisingly a very small percentage of businesses and an even smaller percentage of domestic homes have any form of water treatment.

Approx. seven years ago, in Adelaide, I was confronted by a dramatic increase in failures of Stainless steel booster tanks fitted to commercial dishwashing and glasswashing machines, tanks were lasting only 12 - 16 months!! Chemical analysis revealed high levels of Sodium within the scale at the point of failure.

Considering we had a number of unaffected machines in establishments fitted with base exchange water softeners with the potential to discharge high levels of Sodium into the water, clearly Sodium itself was not the cause. Further investigations ps.
