Grains of Hardness

When a water softener is referring to 'grains' it's talking about how many grains of hardness it can process before regenerating. Grains of hardness processed depends on how large your household is, as well as how hard your water actually is.

For example, a family of 4 with 20 grains of hardness: Your family of 4 will use approx. 300 gallons of water per day (4 people x 75 gallons per person). Since the water has 20 grains of hardness, you'll need to treat 6,000 grains of hardness per day (300 X 20). If you give the softener its full dose of salt, 15 lbs. per cubic foot, you can go about 7-1/2 days before regenerating (45,000/6,000).

Tier1 UV Water Purification System

The VP600M system is effective at eliminating bacteria, cysts, viruses, and much more using UV light as a filtering method.The 30 gallon per minute flow rate is perfect for large homes and small businesses and offices, and is also advised for homes that use well water due to the ability to combat viruses and bacteria that would make it past other filtering methods.
