There are various hard minerals in your tap water and the main culprits that produce hard water are magnesium and calcium. When these two come together, they form hard crystals which will stick to anything they come into contact with, and that’s why you get lime-scale.
SLOW PHOS technology works by altering the ionic charge of these troublesome minerals, which means they won’t be able to stick together and create lime-scale. This results in soft water that’s nice to drink as well as protecting your appliances. It also means that you still get the benefits of the minerals mentioned, which in small doses are good for you.
We are extremely happy with the PureMaster V-700 and FluorideMaster Premium Whole House Water Filtration Systems, and the prompt, helpful customer service we've received. Water pressure was a concern of ours, and we noticed no drop in pressure after the system was installed. We are enjoying the freedom of being able to drink water from any tap in the house, instead of from a water filter installed at the kitchen sink. The water is clear and delicious without the chlorine smell it had in the past. And somehow the bath water now has a lovely shade of blue. Our plumber installed shut-off valves on either side of the filter system - highly recommended for ease of use.
