Three-Way Tap: Hot, Cold & Filtered Water
A three-way tap (sometimes known as a tri-flow tap) gives you hot and cold softened water through the normal levers and main spout, plus a separate hard or filtered drinking water supply through a third lever and spout. It’s a neat, practical solution that declutters your sink area while giving you the best of both worlds — soft water for washing up and cooking and hard or filtered water for drinking.
While softened water is safe to drink, hard water minerals are beneficial to our health, which is why we recommend fitting a hard water drinking feed when fitting a water softener. If you choose to have a separate hard water drinking feed your options are to either install a separate drinking water faucet or a three-way tap, with a secondary decision about water filters or comprehensive reverse osmosis solutions.
We work with trusted suppliers to offer a variety of styles to suit all kitchens, with lasting quality that we know can be supported for many years.

Installation Process
Installing a three-way tap is straightforward. When installing with a water softener, we will:
- Connect the hot and cold softened water to the main spout
- The drinking water line is connected to a hard water feed, usually through a drinking water filter
- We test everything thoroughly and show you how it all works
It’s all part of the same installation visit, and we’ll make sure everything is working smoothly before we leave. You’ll have soft water for washing and cleaning, and hard or filtered water for drinking.

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