What Is Hard Water? Learn Why Your Water May Not Be Doing You Any Favors

Home | Blog | Published on May 12th, 2025

You may have noticed stubborn white spots on your dishes, soap that doesn’t lather well, or even itchy skin and stiff laundry—and wondered what’s causing it. The answer could be something flowing from every faucet in your home: hard water.

Hard water is a common issue for millions of homeowners across the country. While it isn’t harmful to drink, it can lead to a host of problems for your home, plumbing system, and appliances. Fortunately, there’s a simple and effective solution: installing a water softener.

This is an image of a water softener. The headline reads why hard water might be hurting your home.

What Is Hard Water?

Hard water is water that contains high levels of dissolved minerals, primarily calcium and magnesium. These minerals are naturally picked up as water travels through soil and rock, especially in regions with limestone or chalk formations. The more minerals water absorbs, the “harder” it becomes.

Water hardness is measured in grains per gallon (gpg) or parts per million (ppm). A general scale includes:

  • 0–3 gpg: Soft water
  • 4–7 gpg: Moderately hard water
  • 8+ gpg: Hard to very hard water

If you live in an area with hard water, you’ve likely noticed some of the telltale signs—even if you didn’t know the name for it.

Common Signs of Hard Water

Look for these signs to determine whether or not your home’s water source is hard:

  • White or chalky buildup on faucets, showerheads, and sinks
  • Soap scum in tubs and showers
  • Spotty dishes even after washing
  • Clothes that feel stiff or look dingy after laundering
  • Reduced water pressure due to scale buildup in pipes
  • Dry or irritated skin and hair

Over time, hard water doesn’t just cause cosmetic issues—it can also damage appliances and reduce the efficiency of your plumbing system.

How Hard Water Affects Your Home

Hard water can lead to mineral deposits, also known as limescale, inside pipes, water heaters, dishwashers, and washing machines. This buildup can cause:

  • Premature wear and tear on appliances
  • Reduced water heater efficiency, increasing energy costs
  • Clogged plumbing and lower flow rates
  • Increased use of soap and detergent, since hard water makes it harder to lather

Left untreated, these issues can shorten the lifespan of your fixtures and appliances, costing you more money over time.

The Solution: Water Softeners

A water softener is a whole-home filtration system that removes the calcium and magnesium ions from your water through a process called ion exchange. These minerals are replaced with sodium or potassium ions, resulting in softened water that flows more easily and doesn’t leave behind scale or residue.

Benefits of a Water Softener

Improved water quality – Soft water feels smoother on the skin and helps soap and shampoo lather better, resulting in cleaner skin and shinier hair.

Spot-free dishes and glassware – No more scrubbing or re-washing. Soft water prevents the formation of spots and residue, leaving your dishes sparkling clean.

Appliance protection – Softened water extends the life of dishwashers, washing machines, and water heaters by reducing scale buildup and improving efficiency.

Lower utility bills – Without mineral buildup, water heaters operate more efficiently, helping you save energy and lower your monthly bills.

Cleaner fixtures and bathrooms – Eliminate the white crust on faucets and shower doors and spend less time cleaning soap scum off bathroom surfaces.

Gentler on clothing – Soft water helps detergents work more effectively, leaving your clothes cleaner, brighter, and softer—while preserving fabric quality.

Elite replaced my AC & furnace in July 2024. The install technicians were awesome. I would give Elite 100 stars if I could.
