You don’t have to live with limescale. If your Eastleigh home has hard water stains on the shower screen, scale in the kettle, and dry skin after every bath, a water softener will change things overnight. We install trusted systems that tackle the problem at the source, before hard water reaches a single tap.
Our engineers cover the SO50 through SO53 postcodes, fitting softeners from Kinetico, Harvey, Infinity, and TwinTec. Whether you’re in a flat near Lakeside or a family home off Leigh Road, we’ll find the right system for your space and budget.
Eastleigh’s Water Hardness Explained
Eastleigh’s water supply registers at around 240–255 PPM, with an average close to 248 PPM. That’s about 83% on the hardness scale. It’s not the hardest water in Hampshire, but it’s more than enough to cause limescale buildup in pipes, reduce appliance lifespan, and leave your skin feeling dry and tight.
The town’s railway heritage runs deep, dating back to the Eastleigh works that built locomotives for decades. But the geology beneath it is chalk, and that’s what makes the water hard. Every home in the area deals with the same issue.
Choosing the Right System
There’s no single softener that suits every home. A couple in a two-bed flat near Southampton Airport will have different needs than a family of five in a detached house in Chandler’s Ford. That’s why we always start with a free home survey.
During the visit, we’ll test your water hardness, check your water pressure, measure the available installation space, and discuss your daily water usage. Then we’ll recommend a system that matches. TwinTec units work well where space is limited. Kinetico twin-cylinder models are ideal for larger households that need continuous soft water, even during regeneration.

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.”
“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.”
“Fantastic service from the Southern Softflow Team! My enquiry was dealt with promptly and expertly. We were first told by the guy from another local company who installed our water softener (before we owned the property) that the softener couldn’t be serviced reliably as it hadn’t been used for a while and was in any case 10 years old so in need of replacing. We were also told it would be unsafe to use and were quoted a heavy price by him to replace it. Keith from Southern Softflow came to have a look, He was knowledgeable, friendly and very understanding. He spent time analysing the water to make sure it was safe to use. He flushed the system through thoroughly and assured us the softener is in good working order so we wouldn’t need to replace it which was a great relief. Several weeks after Keith’s visit we are using our softener with no issues and are very relieved Southern Softflow operate in our area!”
“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!”
“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 !”
“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.”
