Hard water is one of those things that the majority of people don’t even know exists, let alone affects their house.
But if you’ve noticed your soap not lathering properly, white marks on your tap, or your hair feeling sorta weird after a shower… this could be a sign of hard water.
Now, most people assume you need some fancy water test kit to know if you have hard water. Whilst that’s true, there are heaps of ways to tell if you got signs of hard water just by paying attention to what’s happening around your home.
So if you’re curious (or suspicious), here’s how to get a clue into your water without needing a lab coat or any testing gear.
What Is Hard Water?
Hard water is basically water that’s carrying a lot of minerals in it, mainly calcium and magnesium. It picks these up as it flows naturally through rocks.
That means it’s not “dirty” water, but it can cause a bunch of problems inside your home, especially when it comes to plumbing and appliances.
The sediments can accumulate in pipes making them drain slower, reducing the lifespan of appliances and even blocking the pipes entirely.
Some areas of Australia naturally have harder water than others. Queensland, for example, generally has harder water than other states. Yet, each region and water source differs in hardness.
The Signs
1. Your Soap and Shampoo Don’t Lather Properly
Hard water makes it hard (ironically) for soap to do their job.
Scientifically, what’s going on is that soap is negatively charged. And when the positively charged calcium meets, they cancel out. So in the end, it is less effective at cleaning.
What hard water looks like practically is a residue called ‘soap scum’ being formed. Soap scum doesn’t dissolve in water and when it sticks to your hands, can make it more difficult to lather the soap.
2. You’ve Got Chalky Crust on Taps and Showerheads
One of the most obvious signs is something called ‘limescale’. It looks like a white or cloudy chalky crust that forms around taps, drains, kettles, and showerheads.
It builds up when hard water dries, leaving all the minerals behind. Being made of minerals, it doesn’t just come off like water stains do.
If you’re constantly scrubbing your fixtures but the white crust keeps coming back, there’s a chance that the water is to blame.
3. Your Glassware Comes Out Cloudy from the Dishwasher
You use a dishwasher to clean your dishes. So it can be pretty inconvenient when they come out cloudy or with streaks.
Whilst the what in the dishwasher can evaporate all the water, the minerals stay behind on the surface.
Hard water can also make the detergent less effective, and clog parts of the dishwasher. This can make the dishes come out even worse!
4. Your Skin Feels Dry and Itchy After a Shower
Hard water can even affect your skin!
When you shower in hard water, the minerals can stick to your skin and dry it out. Also, if the soap isn’t rinsing off properly, it leaves a film behind that can make you feel itchy or irritated.
It is natural for skin to dry out, especially in the colder months. However, it could also be a sign that your home has hard water.
5. Your Hair Feels Heavy or Greasy No Matter How Often You Wash It
It’s not unexpected for people with hard water to report that their hair feels dull, heavy or greasy… even after washing it.
That’s because the minerals in the water interfere with your shampoo and conditioner, stopping them from working properly. The leftover mineral build-up in your hair can also weigh it down or leave it looking flat and lifeless.
6. Your Hot Water System Isn’t Performing Like It Used To
Hard water can be quite destructive on hot water systems. The minerals settle at the bottom of the tank and form a thick layer of sediment. This makes it harder for the system to heat your water properly.
Over time, this build-up can cause the system to overwork itself, wear out quicker, and use more energy. You might notice:
- Your hot water is using more energy
- It takes longer to heat up
- The system’s making strange popping or rumbling noises
They can ultimately reduce the lifespan of your hot water system, meaning you’ll have to buy a replacement sooner.
7. You’re Constantly Cleaning But Still Seeing Spots
No matter how much you polish, your sinks and tiles end up looking dirty with white marks or film.
That could be mineral residue.
The problem with hard water is that it can make cleaning feel like a losing battle. It reacts with cleaners, leaves streaks on mirrors and tiles, and dries into spots.
Even in your laundry, it can deposit minerals on your clothes and reduce the action of the detergent. This can leave your clothes feeling stiff or faded.
How Bad Is It, Really?
Hard water certainly is not a plumbing emergency like a burst pipe. However, if you don’t know how to successfully tackle it, it can cost you money later on.
The longer you leave it unaddressed, the more likely you’ll start noticing things like:
- Blocked pipes from limescale
- Reduced water pressure
- Leaks due to corrosion
- Heating bills going up
So it’s worth paying attention to these signs early, even if you don’t have a test kit on hand.
What Can You Do About It?
If you’re worried about hard water there are ways to treat it.
You can:
- Install a water softener to treat the whole house
- Descale your appliances semi-regularly
- Use hard water detergents
You don’t have to fix everything at once, but being aware helps you make better decisions about how to manage your water and protect your plumbing.
It’s about knowing the information so you can make the most cost-effective and beneficial decision for the house you paid for.
Most people don’t know what hard water is. But when you know the signs, you can protect your house from worse problems.
