Product Description
5-Stage Water Purification
The Infinity RO combines five stages of advanced filtration into one compact, all-in-one system. The pre-filter (replaced every 12 months) and RO membrane (replaced every 36 months) work together to remove chlorine, limescale, lead, pesticides, parasites, cysts and other contaminants — delivering nothing but pure, great-tasting water.
Smart Tap Technology
The integrated LED ring on the smart tap provides clear visual feedback on your filter status. Blue indicates more than 150 litres or 15 days remaining, purple warns that the cartridge is nearly exhausted, and red signals it must be replaced. No guesswork, no missed changes.
Effortless Maintenance
Cartridge replacement couldn’t be simpler with the twist-and-lock system. Just three steps: remove the front cover, rotate and remove the old cartridge, then insert and rotate the new one. The system also features quality control, flushing ready indicators, and audio warnings for complete peace of mind.
Better for You & the Environment
Enjoy delicious water on demand from only 2p a litre — more cost-effective than a filter jug. Eliminate single-use plastic bottles (which can take up to 450 years to biodegrade) and enjoy the real flavours of your food, free from chlorine and other contaminants.

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