Perth tap water is safe to drink — technically. But "technically safe" and "actually good" are two different things.
If you've noticed a chlorine smell, a flat taste, or you're quietly spending $40 a month on bottled water because nobody in the house will touch the tap, a properly installed water filtration system fixes all of that in one visit.
Bonza Complete Plumbing and Gas installs whole-home and point-of-use water filtration systems across Perth's southern suburbs — including Fremantle, Melville, Cockburn, Kwinana, Rockingham, and Baldivis.
No recommendation before we understand your setup. No overselling a system your household doesn't need. One visit, one bill.
What's Actually in Perth's Tap Water?
Perth's drinking water is treated and monitored by the Water Corporation and meets Australian Drinking Water Guidelines.
That said, treated doesn't mean tasteless or odourless. A few things contribute to the quality you experience at the tap:
-
Chlorine and chloramines — added as disinfectants during treatment, but responsible for that distinct pool-water smell and taste many Perth households notice
-
Sediment and particulates — particularly relevant in older homes with ageing pipe infrastructure, or properties on the urban fringe
-
Fluoride — added intentionally to Perth's water supply; some households prefer to filter it out for drinking and cooking
-
Hardness minerals — calcium and magnesium, which affect taste and can accelerate scale build-up in hot water systems and appliances over time
None of this is alarming. But if you're drinking from the tap every day, you'd probably prefer it didn't taste like a swimming pool.
Water Filtration Systems We Install
Whole-Home Filtration Systems
A whole-home (or "point-of-entry") system is installed at the main water line before it branches through your house.
Every tap, shower, appliance, and garden connection receives filtered water.
Best suited for:
-
Households concerned about sediment or pipe particulates affecting appliances
-
Properties with older plumbing where water quality varies between taps
-
Homeowners who want filtered water for showers and laundry, not just drinking
Under-Sink Filtration Systems
Installed under your kitchen sink, these filter water at the point of use — specifically your drinking and cooking water.
A dedicated filtered tap sits alongside your existing mixer.
Best suited for:
-
Households primarily concerned with the taste and quality of drinking and cooking water
-
Renters and owner-occupiers who want an effective solution without whole-home infrastructure
-
Anyone currently spending on bottled water who wants to stop
Reverse Osmosis (RO) Systems
A multi-stage under-sink system that removes a broader range of dissolved solids, including fluoride, heavy metals, and nitrates. The most thorough point-of-use option.
Best suited for:
-
Households with specific water quality concerns beyond taste
-
Families with young children or members with sensitivities to particular minerals or additives
-
Anyone who wants the closest thing to pure drinking water from the tap
Inline Fridge and Appliance Filters
Filtration connected directly to refrigerators with water dispensers, or to appliances like coffee machines and ice makers.
Best suited for:
-
Extending appliance life and improving the flavour profile of anything made with tap water
-
Add-on installations alongside a primary filtration system
Bonza on the Job: Water Filter Installation in Action
Why Use a Licensed Plumber for Water Filtration Installation?
Water filtration systems connect directly to your home's plumbing.
An incorrect connection — wrong fittings, insufficient pressure management, or an unsupported splice into copper pipework — can void your home insurance, void the product warranty, and in older homes, cause a slow leak that takes months to surface.
Jared holds Plumbing Licence PL10971, issued under the Plumbers Licensing Board of Western Australia.
Every filtration installation is done to the Australian Standard for plumbing and drainage — which matters not just for safety, but for your Water Corporation account and your home's resale value.
This is not a job for a handyman or a DIY kit from a hardware chain. It's a plumbing installation. It should be done by a plumber.
What Does a Water Filtration Installation Actually Involve?
No mystery. Here's exactly what a Bonza filtration installation looks like:
-
Assessment call — You describe what you're noticing (taste, smell, sediment) and Jared confirms which system options suit your setup and suburb
-
Installation — Bonza will run through the filter installation location and current water configuration with you prior to install. The system is then fitted, connected, and tested for pressure and flow rate before anything is signed off
-
Walkthrough — You're shown how the system works, when filters need replacing, and how to tell if something's off
-
One invoice — No itemised line-by-line billing designed to obscure the total. One price, agreed upfront.
Most residential water filtration installations are completed in a single visit.
