Hard Water in Perth
Understanding hard water, mineral scale and how whole-home filtration helps protect your home.
What Is Hard Water?
Naturally occurring minerals that travel with your water every day.
Hard water contains naturally occurring calcium and magnesium minerals that dissolve into the water as it passes through rock formations and underground aquifers. These minerals are common throughout Perth's water supply and are one of the main reasons homeowners experience white scale deposits around taps, shower screens and appliances.
Hard water may contribute to:
White scale build-up on fixtures and glass
Reduced appliance efficiency
Mineral deposits inside plumbing
Although hard water is considered safe to drink, many homeowners choose to reduce its effects to better protect their homes.
Where Does Hard Water Come From?
The minerals are naturally present long before the water reaches your home.
Hard water doesn't develop inside your plumbing. It naturally occurs as water passes through limestone and mineral-rich geology, dissolving small amounts of calcium and magnesium before entering Perth's water supply.
Common contributors include:
Natural limestone formations
Groundwater sources
Mineral-rich aquifers
Perth's unique geology
By the time the water reaches your home, these dissolved minerals remain present and can gradually form scale deposits throughout your plumbing system.
How Hard Water Can Affect Your Home
Small mineral deposits can have a lasting impact on your home.
Over time, hard water minerals can build up throughout your plumbing system and household appliances. While often gradual, this accumulation may reduce efficiency, affect appearance and increase maintenance requirements.
Hard water can contribute to:
White scale on taps and shower screens
Mineral build-up inside hot water systems
Reduced appliance efficiency
Additional cleaning around bathrooms and kitchens
Reducing scale build-up helps protect the fixtures and appliances you rely on every day.
Why Anti-Scale Protection Comes Second
Each filtration stage has a specific role in protecting your home.
Within the ClearHaven TripleShield system, ScaleShield is positioned after SedimentShield and before CarbonShield to maximise the performance of every filtration stage.
This carefully designed sequence helps:
Remove sediment first
Reduce mineral scale build-up
Protect the CarbonShield cartridge
Improve overall filtration performance
Each stage supports the next, creating a balanced system designed specifically for Perth water.
Industry-Leading Anti-Scale Protection
Powered by the proven OneStop anti-scale cartridge.
Every ScaleShield stage uses the OneStop anti-scale cartridge, a proven technology designed to help reduce mineral scale build-up without using salt or electricity.
Rather than removing minerals from the water, the OneStop cartridge works by interacting with calcium carbonate molecules, transforming them into harmless, non-adhering soft crystals. These soft crystals remain suspended in the water, allowing them to flow through your plumbing system without sticking to pipes, fixtures or appliances before being safely washed away.
Over time, these soft crystals also help attract and bind free calcium carbonate molecules, assisting in the gradual reduction of existing limescale deposits throughout your plumbing system.
Key benefits include:
Helps reduce calcium scale build-up
Transforms minerals into harmless soft crystals
Helps reduce existing limescale deposits over time
Protects plumbing, fixtures and household appliances
No salt, electricity or regeneration required
