Most water quality problems don't announce themselves. They show up gradually — in your bathroom, your kitchen, your laundry, and your power bills — and because the change is slow, many households simply get used to them. Here are seven everyday signs worth paying attention to.
1. You can smell chlorine when you run a tap or shower
That faint "swimming pool" smell is chlorine and chloramine — the disinfectants added to keep water safe in the network. Most people can detect it from around 1 mg/L, and it's often strongest in a warm shower, where the steam carries it straight to you. If you notice it, your water is carrying enough residual disinfectant to also affect taste, skin, and hair.
2. Dry, itchy skin or dull hair after showering
Chlorinated water strips the natural oils that protect your skin and hair. If your skin feels tight after a shower, or your hair feels rough and looks dull despite good products, your water may be working against you. People with eczema or sensitive skin often notice this most.
3. Scale on your kettle, taps and shower screen
White crusty buildup on the kettle element, cloudy film on the shower screen, chalky deposits around tap spouts — that's mineral scale from hard water. Adelaide's supply averages around 97 mg/L hardness (moderately hard), and some northern and western suburbs run higher still.
4. White spots on glassware and cutlery
If glasses come out of the dishwasher with white spots or a cloudy haze that won't wash off, dissolved minerals in your water are drying onto the surface. It's the same residue accumulating, unseen, inside the dishwasher itself.
5. Appliances wearing out early
Hot water services, washing machines, dishwashers, and coffee machines all suffer from what's in the water. Scale and sediment build up inside tanks and elements, making appliances work harder and less efficiently — while chlorine slowly perishes rubber seals, gaskets, and valves. If you're replacing appliances or parts more often than seems fair, water quality is a likely culprit.
6. Tea, coffee and cooking taste a little "off"
Chlorine compounds interfere with the flavour of anything you make with tap water. If your coffee tastes better at a café, or you only enjoy water when it's bottled, your palate is detecting what's in your supply.
7. Sediment or discoloured water after works in your street
If your water occasionally runs brown or cloudy after mains repairs — or your tap aerators keep collecting grit — your home is receiving sediment from the distribution network. It settles in your pipes and appliances even when you can't see it.
Fill a glass with cold tap water and smell it immediately. Check your kettle for scale. Look at your shower screen in the light. Run a finger inside your tap aerator. If you ticked two or more of the signs above, your water has room to improve — and you can look up your suburb's typical chlorine and hardness levels on SA Water's drinking water profile.
What to do about it
None of these signs mean your water is unsafe — Adelaide's supply meets the national guidelines. They're signs of water that's safe but not good, and every one of them traces back to what's dissolved or suspended in the water entering your home.
That's why addressing it at the point of entry works so well: a whole-home system filters sediment down to 5 microns and targets chlorine and chloramine with a 1-micron carbon stage — before the water reaches your shower, kettle, appliances, or skin. If you'd like to know what's achievable in your home, our free water assessment takes about half an hour.
