Have you got Hard Water??? Installing a Filter Systems Australia water softener will remove limescale and eliminate those hard water stains leaving you with soft water saving you time and money.
Twin alternating softeners are ideal for situations where uninterrupted flow of soft water is a must. One resin tank is always in service, while the other tank is in standby. When the meter determines that the resin is near its capacity, it will switch the tank in standby to be in service, and the tank containing the exhausted resin will begin regeneration and wait in standby until the other tank is ready for regeneration.
What is hard water? Hardness is a measurement of calcium and magnesium in water and this can cause staining, calcification and may damage appliances, hot water systems, pipes and fittings over time if not properly addressed. Removing hardness from the water will greatly improve the quality of the water and its effects include lower surface tension, better effects from soaps and detergents, healthier hair and skin, longer lasting appliances (such as kettles, dishwasher, hot water cylinder etc.) and fixtures, less scale build up in showers.
Brief Technical Explanation of how a softener works:
Softeners are full of cation exchange resin. The resin beads have sodium ions attached to them. As the hard water passes through the resin bed, the calcium and magnesium ions swap places with the sodium ions.
The calcium and magnesium ions are left attached to the beads, while the water leaving the water softener contains more sodium ions. The hard water is softened because it no longer contains calcium or magnesium ions.
Once the resin beads in the softener become saturated with calcium and magnesium ions, they must be regenerated by adding sodium chloride (Water Softening salt). The sodium ions replace the calcium and magnesium ions on the beads. Sodium chloride is cheap and widely available, making this a convenient and cost-effective system.

Please note: these systems have been based on treated mains water, if you wish to treat bore water please contact us before purchasing to ensure this system is suitable for your needs.
Please note: These systems exlcude softening salt, we advise you source softening salt locally
