How Do You Know If Your Water Is Hard?

Water hardness is an important factor to consider when it comes to your home’s plumbing and water quality. Hard water can cause a number of problems, from clogged pipes to mineral build-up on fixtures and appliances. But how do you know if your water is hard? In this blog post, we’ll discuss the signs of hard water and how to treat it.


What Causes Hard Water?

Hard water is caused by the presence of minerals like calcium and magnesium in the water supply. These minerals are naturally occurring in many areas, but can be more concentrated in some areas than others. When these minerals dissolve in the water, they form a scale that can build up on fixtures and appliances over time.


Signs of Hard Water


  1. White Spots on Dishes and Glassware

One of the most obvious signs of hard water is the presence of white spots on your dishes and glassware. These spots are caused by mineral deposits that are left behind when water evaporates. You may also notice a film on the surface of your dishes that is difficult to remove.


2. Soap Scum in Your Shower

If you have hard water, you may notice a build-up of soap scum in your shower or bathtub. This scum is caused by the reaction of soap with the minerals in the water, and it can be difficult to remove.

3. Dry, Itchy Skin and Hair

Hard water is also believed to have a negative effect on your skin and hair. Many people with hard water report suffering from dry skin and hair, leaving them feeling itchy and uncomfortable. 


4. Limescale Build-Up

Limescale is a hard, chalky deposit that forms on surfaces that come into regular contact with hard water. It can form on a variety of surfaces, including kitchen and bathroom fixtures, pipes and appliances. It can cause a range of problems, including clogging of pipes, decreased water flow, and damage to appliances if left unchecked. You can find out about how limescale affects your boiler in our blog.

5. Stiff Laundry

Hard water can also affect your laundry. Clothes washed in hard water may feel stiff and scratchy, and they may not come out as clean as you would like. You may also notice that your white clothes start to look yellow or grey over time.



Testing for Hard Water

If you suspect that you have hard water, there are a few ways to test for it. The best way to determine if your water is hard is to have it tested by a professional. A professional will be able to measure the amount of calcium and magnesium present in the water supply and determine if it qualifies as “hard” according to industry standards. There are also test kits available for purchase online that will allow you to test your own water at home.

Treating Hard Water

If you have hard water, there are several steps you can take to address it. One of the most effective solutions is to install a water softener or conditioner – you can read about these different solutions in our previous blog. The Halcyan is a water conditioner. It doesn’t remove the hardness from water, but by conditioning it, the water behaves more as soft water does in your plumbing. The Halcyan not only prevents limescale building up in your appliances and plumbing, but it actually reduces the existing limescale over time.



If you’ve noticed white spots on your dishes, premature breakdown of your appliances, soap scum in your shower, or dry, itchy skin after bathing, you may have hard water. By taking steps to address hard water, you can improve the quality of your water and enjoy all the benefits that come with it.

Knowing whether or not you have hard water in your home is important for maintaining good plumbing health and preventing damage from mineral buildup over time. By being aware of the signs of hard water and treating it properly if needed, you can ensure that your home is protected for years to come!
