I have just had my 18 month old hot water cylinder fail. Both the plumber and the electrician told me they are run off their feet replacing cylinder elements. There is a chemical reaction that occurs when chlorinated water is heated and passed thru copper pipe. The council are now aware of this but are denying any responsibility. So not only are CCC and Dr Alistair Humphreys poisoning half of Christchurch, they are also slowly wrecking our homes. Unfortunately for Dr Humphreys and the CCC, two of the biggest rebuilds in Christchurch – the new Hospital and the justice precinct – are completely piped in copper. Please share as the more ratepayers who know about this the better.

I have just had to have my water cylinder replaced. It was old but chlorinated water may have hurried it along!

Likewise a 2 year old cylinder with 2 elements….both corroded

Our 30 month old cylinder being replaced. And same story from plumber who is flat tack replacing cylinders due to chlorinated water. Our new cylinder is vitreous enamel which we are hoping to get more life from. Since the 2011 earthquake we have now had three new cylinders

I too have had three replacements since the earthquake 😦 Thanks for sharing about the cylinders. I have noticed hot water temperature dropping! What’s to stop the replacement elements corroding?

Why should we have to pay to filter our water…….
– Janice Lisle from Sumner, 08 Aug
It is not only copper elements, as our last one was stainless steel, but the chlorine reacts with the welds on stainless causing the cylinder to leak around where the pipes go in. Hurrumph! Not at all happy with the unexpected cost of having chlorinated water. We were not warned by council of this.

We were not warned by council of this. Agreed. This looks like a liability issue. If a plumber uses initiative to offer a filter system on piping BEFORE water enters tank, they could make a fortune!

“Christchurch plumber Darren Chatwin says July and August have been the busiest months for cylinder repair and maintenance since the Canterbury earthquakes in 2010 and 2011. ‘Our workload regarding hot water cylinders has probably gone up 400 percent’ … Christchurch hot water cylinder manufacturer Superheat have had to double their production over the last five weeks, bringing in extra staff and working overtime to keep up with demand” – Chlorine suspected in Christchurch hot water cylinder failures, TV3 Newshub, 14 Aug
