What Is Hard Water?

Magnesium and calcium make up the majority of the minerals in hard water. The rain and groundwater that finally enters your municipal water supply pick up these deposits from the rocks and soils. 

Also, because it’s challenging to create lather with, hard water is given that name. 

However, the amount of minerals it contains in each grain per gallon (GPG) determines how hard the water is. 

Here is how water hardness is commonly determined: 

  • Softer if the amount of dissolved minerals is less than 1 GPG. 
  • Approximately 1 to 7 GPG of dissolved minerals means the water is moderately hard. 
  • Having 7–10 GPG of dissolved minerals makes it hard. 
  • Very hard – Having dissolved minerals in excess of 10 GPG

Additionally, it’s a typical annoyance that you could encounter on bathroom tiles, in sinks and showers, etc. It can be grayish but is often a filmy, off-white material. 

In addition to being unpleasant in appearance, soap scum serves as a breeding ground for mold. It also serves as a breeding ground for  mildew, all of which have other unsightly colors.

Disadvantages of Hard Water

Asides causing irritating stains to home appliances, hard water has other disadvantages. Here are the disadvantages of hard water;

Lather Formation

When washing clothes in hard water, soap creates a white precipitate instead of lather. The scum is the white precipitate. Your clothes won’t get cleaned if the lather doesn’t form. 


Your clothes get stained by hard water. Instead of lather, the detergent creates scum. Your clothing is then stained by this muck, which also fades the colors. 

Additionally, calcium scum causes your clothing to become scratchy. 

Furthermore, your bathroom’s glass and tiles can all get stained by hard water. The calcium deposits on the bath fittings may build up into a very difficult-to-remove coating if they are not cleaned. That is why we’ve compiled how to remove hard water stains from toilet.

Hair Effects

If you continue washing your hair in hard water, you will continue to experience bad hair days. Your hair gets dry and brittle after being washed in hard water. This is caused by the extra minerals in hard water. These minerals harden into a material that resembles curd and adheres to your hair. 

However, because of this, you might want to wash your hair, but doing so will make it kinky. 

Skin Effects

Taking a bath in hard water can cause your skin to become dry and irritated. This is the case since your body is covered in soap residue. The lingering debris causes eczema-like symptoms. Kids are more likely to experience this problem.

Other Disadvantages of Hard Water

Below are the other drawbacks of hard water;

Reduces the Life of Appliances

If you continue to use your household’s appliances with hard water, their lifespan will be significantly reduced. Appliances used with hard water slowly deteriorate until they eventually fail. 

Additionally, the machines’ efficiency is decreased by the buildup caused by the minerals in the hard water. A dishwasher is designed to last ten years. 

However, the life expectancy is reduced to seven years if hot water is used to operate it. 

Also, a faucet should function similarly for nine years. However, it will only operate for five years if the water is hard. That is how quickly the appliances degrade due to hard water. 

Pipe corrosion

Hard water deposits not only cause the pipe to corrode but also to clog. The amount of water that can flow through the pipe is consequently decreased. And this only makes the water flow slower. 

Also, metals that are unsafe for consumption can leak into water as a result of pipe corrosion.
