What is Hard Water? And How to Treat It

Hard water is something many of us encounter daily, yet few truly understand what it is and why it matters. For homeowners in the UK, it’s important to recognise the effects of this and how it can impact your home, health, and the longevity of your appliances. In this guide, we’ll walk you through everything you need to know about it and how you can effectively treat it.

What Causes Hard Water?

It occurs when water passes through deposits of limestone or chalk, which contain high levels of calcium and magnesium. These minerals naturally dissolve into the water, giving it the characteristic “hard” quality. The higher the concentration of these minerals, the harder the water becomes. In the UK, areas such as London, the Midlands, and South East it is more likely.

Problems Caused

While hardness may seem harmless, it can lead to a range of problems in your home. The most common issue is limescale buildup, which forms on taps, showerheads, and inside appliances like kettles and dishwashers. Over time, this can damage your appliances and reduce their efficiency. This type of water can also leave your skin feeling dry and irritated and make it harder to create lather with soaps and shampoos, resulting in an unpleasant experience.

The Water Scale

To better understand how hard your water is, it’s useful to refer to the water scale. The scale measures the concentration of calcium and magnesium in the water. Here’s a simple breakdown:

  • Soft water: 0–60 mg/L
  • Moderately hard: 61–120 mg/L
  • Hard: 121–180 mg/L
  • Very hard: 181+ mg/L

Knowing where your water falls on this scale can help you assess the level of treatment needed.

How Can I Tell If My Water is Hard?

If you’re unsure whether your water is hard, there are several signs to look out for:

  • Limescale buildup: Look for white, chalky deposits on taps, showerheads, and appliances.
  • Soap scum: If you notice residue on your shower walls, dishes, or skin after using soap, it could be a sign.
  • Dull or rough hair and skin: It can leave your skin feeling dry and your hair looking lifeless.
  • Water taste: Hardness may have a slightly metallic or mineral taste.

If you notice these signs, it’s likely that your water is on the harder side.

Why is it Important to Know?

Understanding it is crucial because it directly impacts the performance of your appliances, the quality of your water, and even your health. By measuring the hardness, you can make informed decisions about the best solutions to tackle common problems like limescale and dry skin. It is also a key factor in determining which water treatment system is right for your home.

How Do Water Softeners Work?

Water softeners are designed to treat the water by removing the calcium and magnesium ions through a process called ion exchange. The water softener uses resin beads that are coated with sodium or potassium ions. As the water flows through the unit, the calcium and magnesium ions are exchanged for the sodium or potassium ions, softening the water. This process prevents the buildup of limescale in your appliances and pipes, making your water more pleasant to use.

Is This Bad for You in the UK?

Short answer: no. However, it can cause discomfort and inconvenience. While this doesn’t pose any immediate health risks, it can exacerbate conditions like eczema and psoriasis due to the dryness it causes to the skin. Moreover, the mineral deposits in this water can contribute to the buildup of scale in pipes and appliances, reducing their lifespan and efficiency.

Can It Affect My Plumbing?

Yes, it can have a significant impact on your plumbing. Over time, the minerals in the water form scale deposits inside pipes, reducing water flow and leading to clogs. These mineral deposits can also build up in heating systems, causing inefficiencies and even leading to costly repairs. Softening your water can help protect your plumbing and extend the life of your water-based appliances.
