  • Soft water 24/7
    The TwinTec S3 provides an uninterrupted supply of soft water 24/7. This is made possible by having two softening tanks, whilst one is regenerating the other is still working to soften your water. So no matter how much your usage varies, you’ll always have soft water.
  • Fits under the kitchen sink
    At just 49cm high, the S3 will easily fit under the kitchen sink – in fact, it was specifically designed with this in mind. The softening tanks have been designed to maximize the available space, whilst still being small enough to fit under the sink.
  • Easy to load block salt
    Conventional softeners require clumsy 25kg bags of tablet salt. They are difficult to handle and often messy. Block salt has proved so popular because each block weighs just 4kgs and loading it into the softener is effortless. Better still, the S3 has a clear lid so you can see when you need to top it up.
  • Uses Less Salt
    It also uses much less salt because thanks to the automatic metering, the softening tanks only regenerate exactly when they need to. This can save you up to 40% on running costs.
  • No programming/electrics
    The S3 has been designed to work solely off the power of your water supply. There are no timers, computers or manual adjustments to be concerned with. What’s more, there is no electrical feed so power cuts are of no concern.
