The Simple Truth About Hard Water vs Soft Water

Hard water vs soft water are the two big water supply categories based on the amount of dissolved minerals that are present.

While not dangerous, hard water can have negative effects on the people, appliances, and plumbing fixtures in your home.

If you don’t know how to tell if you have hard water and what you can do about it, read on to learn more.

What is Hard Water?

Hard water refers to water which contains high levels of natural minerals, specifically calcium and magnesium.

When groundwater filters through mineral deposits such as limestone, chalk, or gypsum underground, it picks up trace amounts of calcium carbonate, magnesium carbonates, bicarbonates, and sulfates.

Hardness can be measured on a scale of water hardness and may cause problems at low levels.

What is Soft Water?

Soft water contains little to no calcium and magnesium compounds but may still have dissolved natural salts present.

Soft water might have a slight salty taste because of the mineral salts or sodium ions in it.

What are the Effects of Hard Water?

Data shows that about 85% of households in the United States have hard water in their homes.

Unfortunately, there are obvious negative effects of water hardness that you may not realize are caused by your water.

Hard Water Stains

Scale, or the white chalky buildup of mineral residue on faucets and in appliances is unsightly and damaging over time.

If you have well water, iron can combine with these calcium deposits to create scale and film that are yellow, orange, red, or brown.

Shorter Appliance Lifespans

Scale deposits can form over time and reduce the water pressure in pipes and water heaters and shorten the life of appliances connected to the plumbing, like your washing machine and dishwasher.

Scale lowers the efficiency of appliances. Every time you operate water-using appliances with hard water, they become less efficient as scale buildup forms on their internal parts and water pipes.

Dry Skin

The high mineral content will strip your skin of natural oils. This means you are likely to experience dry skin and related skin irritation conditions that require you to apply moisturizer.

Hard water when you take showers or bathe can destroy the pH balance of your skin making you more vulnerable to harmful bacteria and infections.

Dry/Damaged Hair

The minerals in hard water build up on hair, making it feel dry and heavy.

The minerals can combine with natural oils to leave your scalp feeling greasy or flaky.

If you have an orange or green tint to the color of your hair, this might be due to the combined effects of city tap water containing chlorine along with those high mineral deposits.

Your locks may look duller, but hair color and highlights can fade faster from both frequent shampooing as well as sunlight exposure.

Dull or Stiff Laundry

You must use more detergent, or the color of your clothes will be dull and feel hard since the washing machine is not as effective.

Clothing colors become duller, and whites are not as white.

More detergents are required to produce sufficient bubbles for cleaning.

Soap Doesn’t Lather

Hard water does not produce as much soap lather, which means you need to use more soap for the same results.

Soft water has less minerals and feels more slippery to the touch.

Food and Drink Taste

Water hardness affects the taste of your drink and food. Soft water used in cooking and drink will have stronger, more pure flavors.

Is Hard Water Safe to Drink?

You might be put off by the presence of calcium and magnesium that affect the water quality, appearance, and taste of the drinking water. However, it is considered safe to drink for people since these two minerals are not harmful to the body.

It is even safe to use hard water for your pet, but research any specific needs of small pets like fish.

If your water is very or extremely hard, you may want to be careful about consuming it since too much can be problematic for some people and pets.

What are the Health Benefits of Hard Water?

Hard water is not dangerous, is safe to drink, and there are some health benefits:

  • Hardness minerals provide your body with more calcium and magnesium. These two primary minerals that contribute to the hardness of your home water can supplement your diet.
  • Health experts claim that hard water boosts your cardiovascular system making it function better.
  • These minerals also protect your body from gastric, colon, rectal and pancreatic cancer.
  • Magnesium protects you from getting esophageal and ovarian cancer.
  • For children and teens, hard water prevents atherosclerosis.
  • Chronic constipation is also prevented since magnesium salt is an effective form of laxative.

How Can You Tell if You Have Hard Water?

Testing your home tap water is the best way of determining the water hardness level. This can be done by a professional or with a hard water test kit.

Without a test, there are still signs that help you know if you have hard water:

  • White scale build-up on faucets, toilets, and in the shower.
  • When you wash your dishes, glassware, and silverware, you might find spots on them after they dry out. These spots are the calcium carbonate present in hard water which is left behind when the water evaporates.
  • Film on your hands after every wash. When soap reacts with calcium carbonate, it forms soap scum that you can feel.
  • After washing your clothes with soap, hard water will leave stains on them and even make your clothes feel dry and brittle.
  • If you find your home water flow to be slower than normal, it could mean that you have hard water that is slowly clogging in your pipelines.

Hard Water Levels

Hardness t is measured in grains per gallon (gpg). A grain is defined as 64,8 milligrams of calcium carbonate dissolved in 1 U.S. gallon of water.

  • Soft water = 0 – 3.5 gpg
  • Moderate water = 3.5 – 7 gpg (you will start to see issues like spotty dishes and dry skin in this range)
  • Hard water = 7 – 10.5 gpg
  • Very hard water = 10.5 – 15 gpg
  • Extremely hard = 15+ gpg

Sometimes hardness is expressed in parts per million (ppm).

1 grain per gallon (gpg) = 17.1 parts per million (ppm).

What to Do About Hard Water?

How to Reduce Water Hardness?

If you have issues with the hardness of your water, the two ways of softening it are to use a water softener or install a magnetic water conditioner.

Water Softeners

Water softeners are a specific type of hard water filter system that works to turn your hard water into soft water.

Just like other filtration systems, you can install a whole house water softening system, under-sink softener or faucet softener.

Water softening devices come in type types and can be salt-based (ion exchange) or salt-free (conditioners).

Magnetic Water Conditioner

These devices use a magnetic field to condition your water from the main line.

It utilizes a magnetic field to change the properties of contaminants in the water.

The result is similar to a salt-free softener where the minerals remain in the water and will not produce a buildup on surfaces, pipes, or fixtures.

How to Remove Calcium and Magnesium Stains

If you have hard water, you can expect to see the effects like having water stains on things that get wet.

It could be on your clothing, porcelain, appliances, shower glass windows and doors and any other surfaces that hard water encounters.

how to clean hard water stains
