Drinking Water System Installation & Filter Fitting
UK drinking water is considered to be some of the safest in the world, but that doesn’t mean it always tastes great or is free of contaminants that may concern you. We regularly hear from customers concerned about things such as microplastics, pharmaceuticals or PFAS, wanting to know what they can do about it. To help guide you, we have pulled together a table which allows you to understand what can be removed and what type of system would best suit your needs.

Filter Replacement & Fitting
Having chosen and installed a water filter which meets your needs the one thing you will need to remember to do is fit replacement cartridges. Cartridges need to be changed after a certain volume of water or within a certain timeframe, regular filter changes ensure your system is able to continue to remove any contaminants you are concerned about as well as keeping your water tasting great.
Once you know how, fitting a cartridge is quite straightforward although this is a service that we offer, and many of our customers like us to do for them. Should you choose this service we will simply book an appointment with you, to suit your diary. One of our engineers will bring the filter with them, fit it for you and talk you through how to do it yourself for the next time if you wish.

Signs you might need to replace your filter
- If you have a system fitted with us we will typically email you when a replacement is due
- You notice a change in the taste of your water
- You can smell chlorine again
- Your filter cartridge looks visibly discoloured (if you can see it)
- You’re noticing sediment or cloudiness in the water coming from your drinking tap

What Our Customers Say
“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.”
“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!”
“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.”
“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 !”
“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.”
