Frequently Asked Questions

What is Luxury Water®
Luxury Water® is hard water which has been treated with a BWT Soft Water System to give a homeowner various benefits which can be seen and felt all around the home. You’ll be amazed at the difference softened water can make to your lifestyle and household budget.


What is hard water? 
Hard water is water that contains dissolved hardness minerals above 100 parts per million (PPM). Relative levels of hardness have been established as:

• Soft Water less than 100 PPM

• Slightly Hard 100 TO 200 PPM

• Hard 300 TO 400 PPM

• Very Hard 400 and above


How does water become hard? 
The rain that falls on land percolates through the ground and rock substrata, dissolving calcium and magnesium salts, giving it its ‘hard’ qualities, along with many other trace elements which affect its taste and flavour. An excess of dissolved calcium makes the water unpleasantly hard, and the result of this is often found in the familiar build-up of scale on sinks and bath tubs.


What is the difference between softening and filtering water? 
Filtering water involves separating mineral particles, like particulates, iron, hydrogen sulphide or other organic matter, from water. Be it through a "filter bed," or "media bed," these undesirable particles are trapped - and the cleaned water passes on through the bed.

Softening water involves something called "ion exchange" to remove dissolved minerals - like calcium, magnesium, iron and manganese - that can't be trapped in a filter bed. Softeners use fresh resin beads with sodium attached to the resin. As water enters the tank, dissolved calcium and magnesium are attracted to the resin. The resin passes up the sodium in exchange for the dissolved chemicals, leaving the water clear of these elements


What is the difference between a physical water conditioner and a water softener? 
A water softener removes the hardness minerals from the water that causes limescale. A physical water conditioner however, does not remove these minerals, but instead alters the characteristics of the way these minerals behave when heated, helping to prevent the build-up of scale on items such as heat exchangers.
