When a family in Swanage noticed their new bathroom suite was already coated in limescale after just six months, they knew something had to change. Like most homes across the Isle of Purbeck — from Wareham to Corfe Castle and beyond — their water supply was extremely hard, testing at around 293 PPM. It’s a story we hear time and again from customers in the BH19 and BH20 postcode areas.

A Common Experience Across Purbeck

Around 92% of properties in this part of Dorset are affected by hard water. The chalky geology that makes the Purbeck landscape so beautiful is the same geology that loads the local water supply with calcium and magnesium. The result? Limescale on every surface that water touches — and hidden build-up inside your boiler, pipes, and appliances that you can’t even see.

The Fix That Made the Difference

After a free home survey from Southern Softflow, the Swanage family chose a compact Kinetico water softener that fitted neatly under their kitchen counter. Installation took under two hours, and within days they could see the difference — cleaner taps, softer laundry, and no more scrubbing at limescale rings in the bathroom. Their story is typical of the results we deliver across the Purbecks every week.

What Our Customers Say

“We recently had Southern Softwater visit our home to walk us through the available options, and the experience from start to finish was excellent.The initial consultation was clear, informative, and pressure-free. They took the time to understand our needs, explained the different systems in a straightforward way, and answered all of our questions patiently. It felt like they genuinely wanted to help us make the right decision rather than just make a sale.The installation process was just as impressive. The installer arrived on time, was extremely professional, and worked efficiently while keeping everything tidy. He explained how the system works, made sure everything was set up perfectly, and left the area clean once the job was complete.Overall, we’re delighted with both the service and the product. It’s rare to find a company that delivers such a smooth and professional experience from consultation through to installation. Highly recommended.”

“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.”

“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.”

“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.”

“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!”

“From the first contact through to survey visit and arranging for installation, this family-run company was excellent, with plenty of communication. The water softener had to be installed in a very restricted space with very difficult to access mains water inlet and drain. However the company plumber found a workaround, even preserving some of the middle shelf in the cupboard concerned. The installation was completed in one morning, working was clean, and the finished job is very neat.”
