No matter what type of water you have a water softener is highly recommended.
Studies have proven that softeners help all of your water supply appliances run more efficiently. A gas hot water heater operated on softened water will maintain original factory efficiency grading over a 15-year lifetime. With-out a softener it can run up to 48% less efficient. Electric water heaters will accumulate up to 30 lbs. of calcium carbonate rock-like scale increasing operating temperatures of the heating element, shortening the life of your heater.
Dishwashers and washing machines will perform better on softened water, using less soap to save you money. Shower-heads and faucets throughout the house will maintain a brilliant luster and full flow. Shower-heads on hard water will lose up to 75% of their flow rate within 18 months. Faucets on hard water will plug after just a few weeks. Studies have shown that softeners are among the “very best’ household energy savers.
