Much of the water that comes out of the tap here in central California is hard, which means that it has more minerals than regular water. This is often caused by groundwater pumping.
Hard water does not pose a health risk: in fact, most physicians agree that minerals, in moderation, are good to have in water.
However, hard water can cause a mineral buildup that damages your appliances. Called “scaling”, this buildup can block water intake valves or damage internal components over time.
HALO systems “soften” hard water, protecting your appliances.
