Our installers are all trained to the highest standards and experienced in fitting water softeners in all of these situations.

It usually takes no more than half a day, though our plumbers never rush – we make sure they have time to do a good, robust and tidy job.

Block Salt

Block salt

A Harvey™ Water Softener needs block salt to function, which needs to be replenished regularly. Harvey Bowden invented the block salt system, which makes topping up and storing salt as easy as possible.

  • Convenient 8kg packs mean no heavy bags to struggle with
  • A year’s supply takes up less space than a set of golf clubs on a trolley
  • Typical usage is one block of salt per person per month
  • The clear lid on our water softener makes it easy for you to check your salt
  • The red line inside shows you when to re-fill or re-order. It’s easy to order here:

How water softeners work

Water softening is the removal of magnesium and calcium minerals from your water supply through a process of ion-exchange. The softened water that’s then produced is kinder to skin, doesn’t leave limescale buildup on pipes, appliances or any surfaces around your home; meaning it shines for longer.

At the heart of a water softener system are two cylinders containing resin. Millions of microscopic beads trap hardness minerals, softening the water as it enters your home. The resin requires regular cleaning (regeneration), which is a process a water softener performs automatically. This regeneration uses block salt, which is manually topped up when needed.

The Harvey™ Water Softener has unique features that give you softened water everyday. Find out more here.
