If you live in Porton, you already know about the limescale. It’s on your taps. It’s inside your kettle. It’s coating the heating element in your boiler right now, quietly driving up your energy bills. Hard water isn’t dramatic — it’s relentless. And Porton has plenty of it.

Our tests across the SP4 postcode show water hardness between 255 and 265 PPM in this area. The average sits around 260 parts per million, which is 85% hard. That chalk downland stretching between Salisbury and Amesbury is responsible. It’s beautiful to walk across, but it loads your water supply with dissolved calcium that wreaks havoc on household plumbing.

Damage You Can See and Damage You Can’t

The visible signs are obvious enough. White scale on taps and shower heads. Cloudy glassware straight out of the dishwasher. Stiff towels and dull hair. But the real cost of hard water is hidden inside your walls.

Copper pipes gradually narrow as scale accumulates. Your combi boiler’s heat exchanger — the most expensive component to replace — slowly loses efficiency under a growing layer of calcium carbonate. Washing machine valves stick. Dishwasher elements burn out. These aren’t problems that appear overnight. They build up over months and years, then hit you with a repair bill you weren’t expecting.

Porton is a quiet village, tucked between the A338 and the chalk downs near Porton Down science park. Properties here range from older cottages in Idmiston to modern houses along the main road. Whatever your home looks like, hard water at 260 PPM is doing the same thing to your plumbing.

Stop the Damage with a Water Softener

We install water softeners from Kinetico, Harvey, Infinity, and TwinTec. A properly sized unit removes the calcium and magnesium from your supply before it reaches a single tap, pipe, or appliance. The limescale stops. Existing scale gradually breaks down. Your heating system starts working the way it should.

Our engineers will visit your property in Porton for a free survey. We’ll test your water, inspect the available installation space, and recommend a system that fits your household. Most installations take less than a day.

We also provide ongoing servicing and salt delivery to keep your softener performing year after year. You won’t be left on your own after installation.

What Our Customers Say

“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.”

“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.”

“Fast response to our enquiry, full information provided, work booked for following week. Fitter arrived on time, pleasant, efficient, very tidy and cleaned up when work finished. Very neat pipework, showed us how to isolate soft water if required at any time, and showed us position of new stopcock. Explained how filter system worked, helped us to set up App for notifications when salt low. Stacked spare salt in garage, advised how to apply for more supplies. Presented us with a delightful gift hamper of locally sourced products. Would highly recommend Southern Softflow Ltd.”

“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.”

“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.”
