All of our water softeners come with a with a 10 year guarantee (please note “guarantee” was mis-spelt) as standard. This is because we are confident you will not experience any problems and will enjoy the benefits of the TwinTec S3 for many years to come.

We're very proud of the quality of our product. Many of the water softeners we installed 10-20 years ago are still in their homes and working well!

Engineered in the UK

The S3 is the latest generation softener from TwinTec. It's been designed and engineered in the UK by Harvey Water Softeners and works with all types of British plumbing systems and all size families, to make life simple. Conforms to British Standard BS14743.

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 washing out the other is still working to soften your water. This means the TwinTec S3 provides you with an uninterrupted supply of softened water, no matter how much water your family uses.

Fits under your 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 maximise the available space, whilst being small enough to fit into tight spaces.

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 S3 and make it as efficient as possible. Because the TwinTec meters the volume of water it softeners, it only washes out when it needs to. As a result it uses less salt than conventional softeners, which can wash out on a daily timer, whether they really need to or not.

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 S3 is so efficient it has been designed to work solely off the power of your water supply. There are no timers, buttons, 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!
