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.

ClearHaven TripleShield whole-home water filtration system installed in Perth, featuring SedimentShield, ScaleShield and CarbonShield with premium copper pipework and pressure gauges.

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.

OneStop anti-scale cartridge used in the ClearHaven ScaleShield filtration stage, helping reduce calcium scale build-up in Perth homes without using salt or electricity.

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

  • Designed for Australian water conditions

Combined with the complete TripleShield system, it provides long-term protection for Perth homes, helping maintain the performance and longevity of your plumbing and appliances.
