What does 33.9 mg/L hardness mean?
How soft water affects your daily life
Appliances & Plumbing
Soft water is gentle on appliances. You won't see limescale buildup in your kettle, hot water system, or washing machine. Appliances last longer and run more efficiently.
Soap & Detergent
Soap lathers easily with soft water. You'll use less detergent for laundry and dishwashing. Clothes come out softer and cleaner.
Skin & Hair
Soft water is gentle on skin and hair. It rinses cleanly, leaving skin feeling smooth and hair soft. Less shampoo needed.
Taste
Soft water has a clean, neutral taste that most people prefer for drinking and cooking. Tea and coffee flavours come through clearly.
Do you need a water filter?
With soft water at 33.9 mg/L, filtration for hardness isn't needed
No action needed
Your water is already soft. No water softening equipment is necessary. A basic carbon filter can improve taste by reducing chlorine if desired.
Utility reports average the grid — not your home
Sanctuary Cove'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.
