How Your Scaleless Stack Water Filter Works
Water Enters through the inlet of the control valave passes through the media bed (Activated Carbon) contained in the
mineral tank. This reduces the chlorine content of your municipally supplied water and reduces taste and odor of the
water. The water then passes through the stack distributor where a scaleless media and goes through the outlet of the
control valve to the house.
The Scaleless system provides protection from scale formation throughout the home.
The Scaleless system can be installed at the point of entry to treat your entire home, both hot and cold water, or
it can be located directly before a water heater or other device (e.g. sauna, etc) that requires protection from hard
water.
Scaleless reduces or eliminates scale formation on internal and external plumbing surfaces as well as reducing
spotting and streaking normally associated with hard water.
Scaleless prevents scale by transforming the normal dissolved hardness minerals into undissolved crystal
micro-particles. These crystals stay suspended in the water and have a greatly reduced ability to react and attach
to surfaces like dissolved hardness does. Therefore the problem of internal buildup of scale in pipes, water heat-
ers and on fixtures and glass is greatly reduced.
Scaleless is not a water softener – Low or phosphate-free cleaning products are recommended to achieve opti-
mum results.
Modern surfactant or detergent based, liquid soaps are preferred over oldfashioned caustic solid soaps.
Unlike softened water, Scaleless treated water maintains the beneficial essential mineral content of your water
and is safe to drink.
