Water treatment supplier Perth, WA

Water filter and softener package for Perth's hard water

Our premium package fits twin 20-inch filters ahead of an automatic water softener, so every tap in the house gets filtered and softened water from one system and one install. It suits most Perth homes on scheme water, which get the best result from both, and it's $5,500 installed.

Filtered and softened water at every tap, in one install

Combined filtration and softening system installation solves two separate problems at once. The filters deal with chlorine taste and smell and catch sediment. The softener removes the hardness that leaves limescale on glass, tapware and inside appliances. Neither system can do the other's job.

As a water treatment supplier, we use our own licensed plumbers for every install, in suburbs from Ellenbrook and the Swan Valley to Landsdale and Joondalup. You get a free water test first, then a fixed written price, with no hard sell.

Why most Perth homes need both

A filter won't stop limescale, and a softener won't remove chlorine. Most Perth homes on scheme water have a reason to want both. Water Corporation adds chlorine to all its supply sources, which is where the chlorine taste and smell come from. Water Corporation says hard water is most common where supply comes from groundwater. Perth's northern system is largely groundwater-fed.

Water Corporation's 2024-25 figures show how much hardness varies across our area. The Wanneroo supply zone averaged 125 mg/L and the Lexia zone, which supplies Ellenbrook and Aveley, 118 mg/L. The Greenmount zone, covering Midland, Guildford and Herne Hill, was the softest at 95 mg/L. All of these are within the national guidelines, so softening is about scale, not safety.

That's why we test first. If your reading is low and scale isn't a problem, we'll tell you the 3-stage filter alone may be enough, and save you the difference.

Combined filtration and softening system installation

The twin 20-inch filter housings go first, then the automatic softener. Filtering first also protects the softener from sediment. Our plumbers fit the whole system in one visit, as close to your water meter as practical. Every tap, shower and appliance downstream is covered.

The automatic softener needs a 240 V power point near the meter and a drain connection. We check both at your free water test, before you get a price.

What the package fixes, and what it doesn't

Fixes

Chlorine taste and smell
Sediment, sand, silt and rust
Limescale on shower glass, taps and tiles
Scale inside your hot water system and appliances
Soap that won't lather and stiff towels
Dissolved iron and manganese staining

Doesn't fix

Bore water problems. If you're on a bore, we test the water first, before anyone talks about price.
Sodium. Softening swaps hardness minerals for a small amount of sodium, so tell us if you're on a sodium-restricted diet.

How the package works

Twin 20-inch filters
Water passes through the two filter housings first, which filter out sediment and deal with chlorine taste and smell.
Automatic softener
The filtered water then flows through the softener, which removes calcium and magnesium and regenerates itself overnight.
Every tap in the house
Filtered, softened water reaches every tap, shower and appliance. All that's left for you is adding salt every few months and changing the filter cartridges when they're due.

Filter and softener package questions from Perth homeowners

Do I need a water filter, a water softener, or both?

It depends on what's bothering you. A whole house filter deals with chlorine, taste, odour and sediment. A water softener deals with hardness, which is what causes limescale on glass, taps and inside your hot water system. Most Perth homes on scheme water get the best result from both. We test your water first and tell you plainly which one you need.

Do The Vines and Aveley homes need both systems?

It depends on your reading. Their scheme water is chlorinated, which a filter deals with. Hardness in their Lexia supply zone ranged from 76 to 160 mg/L in 2024-25, which is the widest swing in our area. That's a softener's job. Your free test shows where your home sits.

Is the package worth it in Midland or Guildford?

Maybe not. Midland and Guildford get water from the Greenmount supply zone, the softest in our area at an average of 95 mg/L in 2024-25. If your test shows little hardness and no scale, the 3-stage filter alone may be all you need. We'll tell you plainly either way.

How much is the filter and softener package in Perth?

$5,500 installed, including GST, for twin 20-inch filters and the automatic softener, fitted together in one visit. That covers a standard installation. We confirm your exact price in writing after a free site check, before you commit to anything.
