I purchased my SofterWater Conditioner model 2034 15 years ago (1997) when I was living in Esperance W.A. Esperance water is the hardest water I have ever come across in that it was impossible to get a lather in the shower and the calcium build-up reduced the volume of water.
After talking to engineers at the hospital who had one of these units on the boilers I installed mine. It took a few weeks to clean the calcium build-up from the pipes and the results were astonishing. When I sold the house and shifted back to Perth I took it with me and installed it at my new address. I honestly cannot speak more highly of the product and installation was so easy.
