Domestic Water Softeners In Dorset, Hampshire and Wiltshire
Hard water affects millions of homes across the UK, and if you’re in Dorset, Hampshire or Wiltshire, you’ll likely know this all too well! You may have noticed limescale on your taps, in your kettle, reduced life on your appliances or dry and irritated skin and hair…the impacts are costly and frustrating. A water softener offers a straightforward way to alleviate these frustrations and make life considerably easier.
We believe that the best water softeners on the market are non-electric water softeners. We proudly supply softeners from the two leading manufacturers; Twintec manufactured by Harveys and Infinity manufactured by Kinetico.

What Our Customers Say
“I have dealt with Southern Softflow for 22 years. Recently after 22 years a fault developed on the machine. The machine was taken away and repaired at a very reasonable cost. As I had moved house I had the machine installed by the kitchen company installing the kitchen and they made a poor job of the pipework needed. When Will from Southern Softflow brought the repaired machine back he rerouted the pipework and put new valves in and did a very neat and professional job. I am delighted. A very genuine and professional company ,a delight to deal with.”
“Southern Softflow’s response to my call for help was amazing, from Edith in the office, Keith the boss man to Will the plumber who worked so hard and did a first class job. A truly great personal service not found easily these days. My heartfelt thanks to them all !”
“Brilliant service. Survey done clear explanation of product from Ben. Fitting done three days later. Very helpful and tidy technician. Added a hard water tap at the last minute no problem. Would highly recommend the service and product. Thanks guys!”
“The service from start to finish was exceptional. Very skilled and knowledgeable plumbers, nothing was too much bother, brilliant receptionist, everything fitted well and explained along the way, went above and beyond - even reinstalled and adapted the cupboard around the new water softener and left us a box full of gifts and goodies! A pleasure to deal with such a great team, we highly recommend them.”
“We've had fantastic service from Southern Softflow from initial enquiry through to installation and beyond. This is our first water softener (TwinTec S5) and we can't fault it (we wish we'd installed one years ago). Southern Softflow's friendly and accommodating service is what set them apart from other companies that quoted. There was no pressure to place an order, and they were very accommodating, as this softener was purchased during a renovation of the whole downstairs, including new kitchen, bathroom & plumbing throughout, so they had to coordinate with our plumber and fit in around other trades. Competitively priced. Fantastic product. Excellent service. I highly recommend Southern Softflow.”
“Moving home to an area with very hard water, I decided it was time to install a water softener. After research, I chose Southern Softflow, who offered exactly the reassurance and expertise I was seeking. Decision to installation took two days. Installation itself took a little over two hours, was carried out neatly, efficiently, and professionally. The new tri-flow drinking tap looks great in the kitchen, and even though I’ve used Brita filters for years, tea already tastes noticeably better after only 12 hours. Many thanks to Ben, Will, and the team, greatly appreciated. A full 10 out of 10.”
