gas hot water unit working

Rinnai units are suited to the water in the area. We were advised against getting a bosch. We live just past worsleys rd on cashmere rd.

repeated HWC and kettle element damage

Frequent HWC element burnouts in beautiful Bowenvale Valley

Starting to lose count of the number of elements we have needed to replace in our home – 1972 original HWC owned house since 1982 (35yrs).

Going back, say last 10-12 yrs – replacement element June 2006, Sept 2010, Feb 2011, new Rheem cylinder with new element July 2011, burnt out July 2015 and again May 2017!!! Thats more than enough replacements – haven’t added up the total cost of parts, van mileage, callout, labour etc.

Our electric jugs/kettles arent lasting and have had several Sunbeam plastic and s/s models replaced under Warranty or just out of Warranty period. Our current s/s Breville has been leaking water from base for several months until it got so bad needed to buy replacement last weekend! Still locating Warranty but when found (tonight?) we should obtain a refund under the CGA!

Also in recent months the inside of our electric jug is a daily, if not several times weekly, task to try to keep clean of scale! Even the new jug which is only 5 days old has signs of build-up already. Prior to this purchase, a retailer told us that a Warranty may not cover a leaking jug because of liquefaction getting into the water supply, but we didn’t have liquefaction from the quakes in our area!

titanium element much better

We were a rebuild (Brickworks Lane) and had a brand new cylinder. We went through three elements (One every three months). They finally replaced it with a titanium element on Christmas Eve! This seems to have fixed the problem.

gas-fired water system damage too

10 years ago we had trouble with corrosion with our Rheem gas water system while it was still under warranty. They said it was due to the water in these areas ‘hugging the hills’ and they’d had to replace several around here. We’re in Stanbury Avenue. They imported parts from Japan that were designed to cope with this water and, fingers crossed, it’s fine now.

Hi Rik

I’m not aware of any chemical analysis being undertaken in the Cashmere area since the testing we completed around September last year (reports attached). We do regularly test for bacteria as part of our ongoing monitoring just not any chemical analysis in this area. [Reports are here:
cashmere-drinking-water-2016-08-03-ccc-lab-report-160802001 155kB PDF]

It’s really important to note that you can’t read these results in isolation. What I mean by that is just because there is a specific result from one well that doesn’t mean you will be getting that same result in the street or through your tap. For example Spreydon Well’s 3, 4 and 5 all flow into a suction tank, from there the water is pumped into the network. Another point to remember is not all of these wells are run all the time. In my view we should be looking at the averages more so than individual results. This is especially true for ph. I would say the results for the three properties we tested would be the results to take most notice of. [Summaries here:]

Attached are two maps of the Cashmere area that should assist. When looking at them note that typically a reservoir doesn’t feed the zone it sits in, it feeds the next zone downhill. If you want a different view let me know and I can send you a different version. [Zoom view here:]

In my view the water quality is very similar across all of Christchurch City, there are no specific locations or suburbs with known water quality issues.
