“i have a 1 bathroom home, and live on a lake with a well and my water is very hard (35 grains per gallon) what is best system. Will a no-salt water softener work for me? We also have a trace amount of iron, about 0.3 PPM”
For water this hard, we recommend a 48K grain softener, not a salt-free water conditioner. We recommend a water softener, not a scale-stopper conditioner because the level of hardness of your water can be better handled by a water softener system. The 48k grain softener is the best treatment system for your water right now.
Softener 5900 Series, 48K Size
Includes 1 inch or 3/4 inch pipe connectors; by-pass valve; 1.5 cubic feet of high-grade softener resin; heavy-duty brine tank with salt-grid; and 165 Series NSF Certified digital metered-regeneration control valve.
