What Is Water Hardness?

Water hardness measures the quantity of calcium and magnesium dissolved within the flowing water of a plumbing system. According to the science of water hardness, the most common sources of hard water are groundwater wells that allow minerals in the soil to transfer to the water.

Many homeowners ask if the hardness of their water matters. However, hard water can cause various problems for you and your plumbing systems. Some of the main problems caused by hard water include:

  • Dry hair or skin after bathing
  • Difficulty with soap lathering during bathing
  • Scale buildup in plumbing systems
  • Water spots on laundry or dishes
  • Inefficient water flow
  • Increased water consumption and expenses

The Importance of Water Softener Efficiency

When asking, “How big of a water softener do I need?” it helps to understand why this system’s efficiency level matters. Water softeners use the sodium from salt to offset the magnesium and calcium concentration in your water supply. 

Because of its sodium use, you will need to supply your water softener with salt to maintain the machine’s efficacy. Utilizing an inefficient water softener will require you to buy more salt for your softener and increase the regeneration frequency. These factors can cost you over time.

Properly Sizing Your Water Softener

Getting the right size water softener saves you money and hassle by minimizing salt use and maximizing soft water capacity. Professionals from Rainforest Plumbing & Air can advise you on the best size options for your water softener.

Factors Impacting the Right Water Softener Size

There are a few factors that impact the size of the water softener you need. From the water hardness of your source to your daily water needs, identifying these factors will indicate the best-sized resin bed for your water softener. 

Water Hardness

Your water hardness measures magnesium and calcium levels. Depending on your water source, you might have to test the water to identify its hardness.

Measures of water hardness usually come in the unit of milligrams per liter (mg/L) or grains per gallon (GPG). Every 1.0 ppm of iron present in the water offsets the water hardness by three grains per gallon.

Daily Water Use

Your daily water consumption levels directly impact the size water softener necessary. In order to determine your water usage, multiply the amount of people living in your home by 75 gallons per day (the national average). However, if you host frequent visitors, friends, and family in your home, you might consider getting one size above what you need.

Daily Softening Requirement

The daily softening requirement for your home combines your water hardness with daily water use. Multiply these numbers to get your softening requirement.

Matching the Conditions With a Water Softener Size

Because most water softeners require weekly regeneration, you will need to multiply the daily softening requirement by seven to identify the right size. For example, if your daily softening requirement is 3000 grains, you will need a resin size that can efficiently support 21,000 grains per week.

High Salt-Efficiency Water Softeners

The salt-efficiency rating of water softeners plays a role in how well these machines work, too. The following figures demonstrate the efficacy of different-sized resins with salt efficiency:

  • 0.75 Cubic Feet = 15,000 Grains 
  • 1.0 Cubic Feet = 20,000 Grains
  • 1.5 Cubic Feet = 30,000 Grains
  • 2.0 Cubic Feet = 40,000 Grains
  • 3.0 Cubic Feet = 60,000 Grains
  • 4.0 Cubic Feet = 80,000 Grains
