Cuprosolvency<br />
Cuprosolvency is typified by general<br />
corrosion of copper pipe releasing slightly<br />
elevated levels of colourless soluble<br />
copper into the drinking water.<br />
There is no noticeable change in the<br />
colour or clarity of the water and whilst the<br />
integrity of the copper pipe is unaffected,<br />
staining of sanitary ware (Figure 6.3) and<br />
clothing can occur.<br />
It is typically associated with dripping water<br />
taps or a particular soap that reacts with<br />
the low levels of copper and can readily be<br />
removed using ammonia-based cleaning<br />
agent.<br />
It’s Occurrence<br />
Information gathered about this<br />
phenomenon indicate that it has been<br />
associated with untreated cold water<br />
typically in rain water tanks systems and is<br />
associated with:<br />
• Water, which have no residual chlorine or<br />
disinfection system.<br />
• Soft waters with low pH
