What are the differences, how do they affect me, what are my options?


Water filtration can be a confusing and complex subject for some, with many wide-ranging topics. For most homeowners, the issue of hard vs soft water is among the most prevalent issues they may face. Read on to learn more about this topic.

What is Hard Water?

Water is considered to be “hard” when it contains an abundance of calcium and magnesium. While these two minerals are considered to be healthy and essential, they are not ideal for your home and need to be addressed.

Hardness is measure in Parts Per Million (ppm) and is commonly reported in Grains Per Gallon (GPG), with 17.1 Parts Per Million = 1 Grain Per Gallon. Water Softeners are commonly deployed in residential applications where water hardness exceeds 3 Grains Per Gallon (or 51.3 Parts Per Million).

As the levels of these two minerals rise, so does your risk. Over time, a buildup of lime (from the calcium and magnesium) will form in your pipes. Eventually, any appliance or fixture that uses water also will form buildups too. You will soon notice some of these common signs:

  • A decrease in water pressure
  • Dishes have a cloudy residue after going through the wash
  • Clothing and bedding becoming dulled and scratchy after using the washing machine
  • Dry or itchy skin and hair after washing or showering, especially in winter months
  • Unexplained higher water or heating costs
  • Unsightly lime buildups in sink and showers
  • Premature appliance failures
  • Poor tasting drinking water

What is soft water?

This water is ideal for your household! Soft water simply contains little to no calcium/magnesium. Specifically, USGS defines this as water with 17.1ppm or less. You will notice an increase in appliance efficiency and will no longer be subjecting your skin and hair to these dehydrating minerals.


Hard water is a very common issue many in America face today. If you believe your home has hard water, we would be more than happy to help guide you through the uncertainty and put together a comprehensive water treatment plan.
