Chlorinated Water & Water Cylinders

Chlorinated water not only leaves a nasty taste in your mouth, but it is also corrosive on copper, brass, copper, galvanized iron, stainless steel pipes & fittings making them prone to leak. It can even wear away the protective alloy coating on heating elements causing them to fail.

“Chlorine is likely to be to blame for the failure of some hot water cylinders in Christchurch, according to a report issued by a University of Canterbury scientist. The analysis was performed by Professor Milo Kral on four hot water cylinders, from three different brands, that had suffered corrosion ‘pitting’.” For more information, click here to read Newshub’s report on hot water cylinder failures in Christchurch.

If you live in an area that has chlorinated water, such as Christchurch, it is advisable to check regularly for any signs of damage before leaks occur. Signs of possible corrosion include white build up (calcification) around fittings or blue-green stains in baths or sinks.

Left unresolved corrosion can lead to major leaks, structural damage & possibly even health issues caused by damaged pipes & fittings contaminating your drinking water.
