Why Hard Water Is a Problem for Most Australian Households
Why Hard Water Is a Problem for Most Australian Households

Hard water contains elevated levels of minerals including calcium, magnesium, iron and sulphur compounds. While safe to consume, these minerals can accumulate in pipes and appliance components. Over time, this leads to reduced flow rates, increased energy demand and potential equipment failure.

A professionally installed water softener system removes these hardness minerals, providing reliable hard water treatment that maintains system performance, appliance efficiency and water quality.

Prevent Mineral Buildup with a Home Water Softener System
Prevent Mineral Buildup with a Home Water Softener System

Hard water contributes to scale accumulation on plumbing surfaces, fixtures, and appliances. This reduces flow efficiency and increases operational strain.

Installing a home water softener slows scale formation and helps maintain stable water pressure and performance across the property.

Eliminate Soap Scum and Improve Cleaning Performance with a Soft Water System
Eliminate Soap Scum and Improve Cleaning Performance with a Soft Water System

A soft water system also lowers detergent usage and improves washing outcomes.

Water Softener System Reviews

“Great service and support. Great Water Filters send me an annual reminder when my filters are due, they keep records so I get the right filters at the right time.
Support is unparalleled. I get help when I need by phone and in the event of something going wrong, Great Water Filters had a representative from WA to help resolve the issue in one visit.
Phone support, ordering additional filters (for showers), and response times are excellent. I recommend them highly!”
Peter H.27 August 2024
“Quality finishes, water and customer service. From meeting Paul at the Home Expo, to engaging with Levon to help plan and work through all our queries and ultimately to Shannon implementing the system we're delighted with the result and enjoying the filtered water at every tap point in our home...and without loss of pressure. Thanks Great Water Team!”
Yianni S.27 August 2024
“Fantastic experience from start to finish. No pushy sales like the other company we enquired with. We kind of knew what we wanted, and any questions we had were answered honestly and concisely. We’re loving having filtered water throughout the whole house with no noticeable water pressure loss. Thanks for being such a wonderful company to deal with. I have already recommended the whole home filtration system to several of our family and friends”
Christie K.27 August 2024
“Very happy with the quality of the product and the service. We have gone from having dirty, hard water (awful town supply!) to clean water that feels soft after the installation of a whole-house filter. The whole process was quick, taking less than a week from my first approach to Great Water to the filter being installed. The plumber assigned was friendly and professional. A very small amount of seepage we had after installation was fixed within a day after one text message to Great Water. While the price may put some off, we see it as a saving on the jug filters we no longer need to buy, and on the damage the old hard water used to do to the bathroom, kitchen and cars. I would definitely recommend Great Water's household filter system.”
