What our customers say

“We’ve had a Minimax for about a month now and we’re wondering why we didn’t get one years ago. With the water being scale-free, faucets, taps and sinks get shiny with just a wipe and no cleaning detergent.

We had our old water softener for 14 years, and when we asked our supplier for a new one, this is what we got, and it’s brilliant. A non-electric item, it just does its job without having to worry about power failures, all you do is pop in the salt blocks.

It’s a neat unit and installation was done by Vickery Water Softeners, who were knowledgeable, professional and expert at problem-solving when the need arose.
We felt we were in safe hands!
