What does 112 mg/L hardness mean?
How moderately hard water affects your daily life
Appliances & Plumbing
Moderately hard water can cause minor limescale buildup over time. You may notice white deposits in your kettle. Descale appliances every few months to maintain efficiency.
Soap & Detergent
Soap lathers reasonably well but you may need slightly more detergent than with soft water. Some soap scum may appear on glass surfaces.
Skin & Hair
Moderately hard water is generally fine for most people. Some with sensitive skin may notice mild dryness. Hair may feel slightly less smooth after washing.
Taste
Moderately hard water has a slight mineral taste that many people find acceptable or even pleasant. It's safe to drink.
How to deal with moderately hard water
Recommended solutions for 112 mg/L hardness in Adelaide River
Reverse Osmosis (RO) System
The most effective solution for hard water. Removes 90–99% of dissolved minerals including calcium and magnesium. Installed under the kitchen sink for drinking and cooking water.
Ion Exchange Water Softener
A whole-house solution that replaces calcium and magnesium ions with sodium. Prevents scale in all pipes and appliances. Requires salt top-ups every few weeks.
Carbon Filter
A carbon filter won't help with hardness — it only removes chlorine, taste, and odour. You need a reverse osmosis or ion exchange system to reduce hardness.
Utility reports average the grid — not your home
Adelaide River's water meets ADWG standards at the source, but old pipes, roof tanks, and ageing plumbing can add lead, copper or bacteria before the water reaches your tap. These won't show up in your utility report.
Check your own tap before buying a filter or assuming the suburb average matches your home.
