How it works
Hard water pumped into your home passes through a bed of resin crystal beads in the unit which capture the lime scale and minerals by an ionising process. When the beads become exhausted, they need to be regenerated by flushing through a salt water solution. Because of its technologically advanced design and unique features, Dualflo has more efficient operation than conventional models, which makes it the best performer on the market.
The salt is not used to soften the water, but is used to release the hardness minerals from the resin. This process is called regeneration. With the Dualflo non electric operation, Block Salt is the only consumable product. Even here the Dualflo is more efficient and cheaper to run than other softeners. This is because the Dualflo’s unique control system uses the exact amount of salt necessary to regenerate the resin, and does not rely on a pre-programmed estimate of water usage.
