Water droplet splash

Softened water 24/7

Our water softeners pack a little more punch than all the rest as they have two cylinders, unlike the industry standard of just the one. So whilst one is regenerating the other is still working to soften your water. This means the TwinTec S4 provides you with an uninterrupted supply of softened water, no matter how much water your family uses.

TwinTec S3 Softener under the kitchen sink

Fits under your kitchen sink

At just 49cm high, the S4 will easily fit under the kitchen sink - in fact, it was specifically designed with this in mind. The softening tanks have been designed to maximise the available space, whilst being small enough to fit into tight spaces.

Height: 490mm
Width: 205mm
Depth: 440mm

Inserting salt into the softener

Easy to load block salt

Our block salt was created for easy loading so that you don't find yourself handling unnecessarily heavy bags of salt. The specially manufactured salt was created to work with the S4 and make it as efficient as possible. By ensuring that the salt lasts longer the softener only regenerates when it needs to, rather than on a daily timer like other systems.

When salt needs to be topped up there is a red line that is visible through the clear lid design, which makes it easy for you.

Non electric

The S4 is so efficient it 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. Sustainable energy, without the need for a power outlet. Genius!

"The water improvement is wonderful. I feel it every time I wash my hands. I had forgotten that water could be so soft. Best of all, the dry cracking skin on my hands improved immediately and is now a thing of the past."
