Domestic Water Softeners In Dorset, Hampshire and Wiltshire

Hard water affects millions of homes across the UK, and if you're in Dorset, Hampshire or Wiltshire, you'll likely know this all too well! Whether it is the limescale on your taps and shower screens, the deposits in the bottom of your kettle, the regular calls to the boiler engineer or dry and irritated skin and hair...the impacts are substantial and frustrating. A water softener offers a straightforward way to alleviate these frustrations and make life considerably easier.

Southern Softflow offer straightforward, honest advice and solutions that we believe will best serve our customers for the long term, based on over 35 years experience. As an independent local supplier, we are very deliberate in the softeners we choose to supply and we place huge emphasis on reliability, ease of use, and efficiency.

We believe that the best water softeners on the market are non-electric water softeners from the two leading manufacturers; Culligan Harvey and Kinetico. Southern Softflow are an exclusive Elite Dealer for Culligan Harvey and part of the highly exclusive dealer network for Infinity Water Softeners.

The key benefits to non-electric water softeners are:

  • No electrical programming required
  • Twin cylinder design means you are guaranteed soft water 24/7
  • Regeneration is determined by your household water usage
  • 10-year parts warranty
  • No need for annual servicing
  • Simple to use, just load block salt into the machine
