4. Will Care-Free Help Remove Chlorine Taste From Our Water Supply?

Will Care-Free Help Remove Chlorine Taste From Our Water Supply?


Yes. Laboratory tests have confirmed you can look forward to a reduction of 70% in the concentration of residual chlorine in Care-Free conditioned water. This decrease is due to the freeing of the chlorine artificially trapped between the mineral particles of the water before being conditioned. It is freed into the atmosphere in gaseous form as water leaves your tap.

With a Care-Free system fitted you get the benefits of chlorination, but without the taste.

5. How Does A Care-Free System Give Me Clearer Water?

How Does A Care-Free System Give Me Clearer Water?


Turbidity (the measure of the degree to which the water loses its transparency due to the presence of suspended particulates) is caused by microscopic suspended particles in your water supply. Laboratory tests confirm a decrease of 20% in the turbidity of the conditioned water.

Your Care-Free Conditioner causes the mineral particles to repel each other, separate and become smaller. Because there is less light refraction from the smaller particles your water becomes clearer. This is especially evident in swimming pools.

6. Will A Care-Free Conditioner Give Me Cleaner Softer Clothes?

Will A Care-Free Conditioner Give Me Cleaner Softer Clothes?


Yes. Conditioned water contains smaller particles, which pass more readily through the clothes being washed. The water tends to be “wetter”, and penetrates better to carry away dirt and grease.

In unconditioned water, larger particles and other substances can become trapped in detergent and in the fibres of the clothes you are washing, causing staining.

7. How Will it Provide Improvements For Nurseries, Vineyards, Gardens, Crops & Lawns?

How Will a Care-Free Conditioner Provide Improvements For Nurseries, Vineyards, Market Gardens, Crops & Lawns?


Bottom line…you will have greener, healthier more robust growth with less water. You can also look forward to increased yields, which means more profitability because:

the better “wetting action” of conditioned water improves soil texture by surrounding individual soil particles with tiny droplets of conditioned water. Not only does your soil become more permeable but also it is able to retain its moisture content for longer periods;

by improving the permeability, salts which previously accumulated around root systems and in the soil are leached away and do not reform. Plant stress is relieved and improved growth is noticed in weeks – sometimes only days; and

mineral particles and salts in the conditioned water no longer adhere to leaves to the same extent and what’s more, leaf burn is reduced considerably – a major benefit.

NOTE: Laboratory LEAF ANALYSIS testing on an orchard of stone fruit trees between Conditioned and Unconditioned water, confirmed a massive 66% reduction in Sodium and 52% reduction in Chloride in the Conditioned water.

8. What Level Of Salinity Can Be Treated For Irrigation?

What Level Of Salinity Can Be Treated For Irrigation?


Our records confirm the successful flood irrigation of lucerne with bore water, which, after conditioning, had the following analysis:

pH 6.9

Conductivity 11100 uS/cm

Chloride 3400 mg/L

Sodium 1640 mg/L

Total Hardness 1986 mg/L

Sodium Chloride 5600 mg/L

NOTE: This salinity level is about four times the tolerance for lucerne. Although the soil had good drainage, the saline water almost destroyed the lucerne crop before the Care-Free Conditioner was installed. (Installation details: 75mm Care-Free Conditioner fitted to a 150mm line.)

9. Will Care-Free Reduce Salinity Build Up In The Soil?

Will Care-Free Reduce Salinity Build Up In The Soil?


Yes. Care-Free has been granted a Soil Desalination Patent. Soil Analysis tests in a number of applications have confirmed a substantial reduction.

For example: after irrigating turf grass for only six months after installing a Care-Free Water Conditioner, with the Care-Free Water Conditioner the reduction in the soil salinity level was very apparent. The results were as follows:

Before After % Reduction
pH 7.0 6.8 3%
Elec. Cond. 0.33mS/cm 0.19mS/cm 42%
Total Salts 980 ppm 564 ppm 42%
Sodium 184 ppm 115 ppm 37%
Chloride 290 ppm 140 ppm 52%

10. Will a Care-Free Water Conditioner Save Me Water in Irrigation?

Will a Care-Free Water Conditioner Save Me Water in Irrigation?


Yes. Conditioned water is absorbed more rapidly into the ground and therefore reduces evaporation. Consequently watering time is shortened which means you save three valuable resources – water, energy and money.

We suggest reducing your watering time by up to 20%. In fact some customers report water savings of 30%.

11. What Level Of Calcium Carbonate (CaCo3) Hardness in Water Can Still Make it Usable For Households?

What Level Of Calcium Carbonate (CaCo3) Hardness in Water Can Still Make it Usable For Households?


The National Health and Medical Research Council Guidelines for CaCO3 hardness state 500mg/l is the maximum. Care-Free has undertaken numerous tests with applications in very hard water and it has proved successful in reducing or in some cases eliminating scale build up. For example, the properties of the water in the following test was considered Hard to Very Hard and hot water systems used with this water had very short life expectancies. The water contained the following properties:

pH 7.5

Total Solids 915mg/l

Calcium 77.2mg/l

Chloride 301mg/l

Alkalinity 267mg/l

Hardness (as CaCO3) 346mg/l (Hard to Very Hard)

When an inspection of hot water systems was carried out after 18 months of Care-Free conditioning, no evidence of any scale build up was found. The Local Water Authority reported tubes and cylinders were in excellent condition.

12. How Does Care-Free Affect Calcium Carbonate (CaCo3)?

How Does Care-Free Affect Calcium Carbonate (CaCo3)?


Calcium Carbonate appears in predominately two forms, Calcite (CaCO3) and Aragonite (CaCO3). They have the same chemical composition but have different crystalline structures.

Calcite precipitates to form hard to remove whitish scale.

Aragonite is much softer and is more easily removed.

Testing by ANSTO confirmed that the crystalline structure of Calcium Carbonate in its Calcite form was changed to Aragonite when the Care-Free Water Conditioner was used, hence its easy removal.

Over the years, Care-Free has aroused the attention of several scientists. In fact, an Australian scientist recently completed a thesis on Care-Free and scale removal. Click here to read more.

13. Can You Help My Manganese Or Iron Problem?

Can You Help My Manganese Or Iron Problem?


We have found that with high concentrations of Manganese above 0.5mg/l and iron above 1.0mg/l, the Care-Free Water Conditioner requires more frequent cleaning.

Note: With iron and manganese problems – the conditioner must be down-sized – please check with your dealer or contact us.

14. How Does Care-Free Remove Rust And Scale From Our Plumbing System?

How Does Care-Free Remove Rust And Scale From Our Plumbing System?


In conditioned water the mineral particles repel and lose their attraction to each other and the surfaces of pipes, elements, valves, rods and other equipment.

Being a solvent, the water now slowly etches, loosens and dissolves the existing scale and rust from the system. We have found that once clean your system will stay clean!

15. What Happens To The Pipes And Equipment After Scale Is Removed?

What Happens To The Pipes And Equipment After Scale Is Removed?


The Care-Free Conditioner causes a natural protective carbonate film to form inside the equipment and piping, which will not grow or increase in time. This self-healing greyish film is of negligible thickness and not only protects the system against scale and corrosion, but will not impede water or heat flow.

In old, corroded systems it is possible for scale to seal a leak. So removing the scale may cause the pipe to leak. (In this case the pipe should be replaced.) Nothing further will happen – except that you will have clean pipes!

17. What Happens When Conditioned Water Is Held In Storage Tanks?

What Happens When Conditioned Water Is Held In Storage Tanks?


Care-Free treated water will maintain its conditioned state, unlike magnetic or electronic water treatment devices, where the water reverts back quickly to its original form.

Seed propagation tests using Care-Free treated water which had been stored for eight weeks, confirmed that the water remained in its conditioned state.

Periodically it may be necessary to drain the lower region of the tank in order to expel any high concentration of dissolved solids that settle on the bottom.

18. What Will It Do For My Algae Problem?

What Will It Do For My Algae Problem?


The Care-Free Water Conditioner, by virtually eliminating the biofilm on the water,

denies the algae its food source. This occurs because of the mineral separation process. With nothing to feed on the algae is either greatly reduced or completely eliminated.

20. What Happens When Care-Free Is Fitted Before A Reverse Osmosis Or Carbon Filter?

What Happens When Care-Free Is Fitted Before A Reverse Osmosis Or Carbon Filter?


The Care-Free Water Conditioner neutralizes the negative influence of mineral particles, which otherwise tend to hinder the filter’s performance and reduce the working life of reverse osmosis membranes.

Installing a Care-Free unit before the carbon or reverse osmosis filter, keeps the filter cleaner and greatly improves its efficiency. We have seen longevity of membranes and filter cartridges extended by several times

21. Where Do I Install The Care-Free Conditioner?

Where Do I Install The Care-Free Conditioner?


In most applications and particularly domestic household applications, your Care-Free Water Conditioner is best fitted into the main line after the water meter or pump and before any tee junctions or holding tanks, whereby the whole system will benefit. Your Care-Free Water Conditioner will operate at any angle, above or below the ground.

When fitted below ground it must be installed in a suitable size box or pit, which allows access to unions for cleaning. On larger installations where it is impractical to install a Care-Free Water Conditioner on the water meter due to variation in flow, several smaller Care-Free Conditioners may be fitted on branch lines within the property.

Important: When watering or irrigating from a short discharge pipe, it is extremely important to prevent air from entering the conditioner as cavitation will result and oxide may form on the catalyst core, impairing performance. If cavitation occurs reduce the outlet slightly to obtain a “full pipe” of water and so eliminate this problem.

NOTE: Do not install or test the conditioner at the end of the pipeline.

24. Does The Care-Free Conditioner Have Any Government Approvals Or Endorsements?

Does The Care-Free Conditioner Have Any Government Approvals Or Endorsements?


Yes. Below is the WaterMark Certification (No 23046) for the CF6 through CF50 Care-Free Water Conditioners to Australian Technical Specification ATS 5200.103.2004 – plumbing and drainage products Part 103: Water Treatment Systems (other than those specified in AS/NZS 3497).

In layman’s terms this standard covers water treatment systems for potable water – that for human consumption.

Each Care-Free Water Conditioner in this range carries the WaterMark Certification emblem.

Click here to view the full certificate.

Further, Care-Free Water Conditioners have been assessed by the Department of Health NSW and the Director General has given a conditional approval to the process. Our approval number is PDA-032.

After two years of testing, the State Electricity Commission, Portland Victoria, (Powercor) endorsed the conditioner. To quote: – “We conclude that it was beneficial to install these units to lessen the costly replacement of hot water cylinders, anodes and elements. It would be a real benefit to install a water conditioner on all residences within the Portland Water Board region.”

The Benalla office of the Victorian Health Department has also given an endorsement. And to quote from an extensive report: – “Every condenser tube was completely clean and shining like a gun barrel.

The two-year field test experiment has thus far substantiated that aquatic environment of a cooling tower and an evaporative cooler can be controlled using what has traditionally been known as a proprietary device.

The evidence supporting this is the visual results of the experiment and the certified NATA laboratory test results of the water samples.”
