About TwinTec

TwinTec Water Softeners are the most advanced block salt, non-electric water softener ever made. Designed and manufactured in England, discover the difference that softened water can make in your home.

Designed by leading manufactures in the UK

The TwinTec S4 has 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 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.

The amazing benefits of having a water softener

Did you know that investing in a water softener saves you money in the long term? With softened water, appliances last longer and are less likely to break. Your boiler and pipes will stay unblocked, which results in them running more efficiently; saving you money on your heating bills.
We have been using the TwinTec S4 with total satisfaction for over 5 years now. It is simplicity itself. The machine is small and unobtrustive, absolutely maintenance free and silent in use. I have owned a number of softeners, but never one as efficient as the S4.
