Tankless reverse osmosis · Sydney
Tankless reverse osmosis in Sydney: the ED600, $1,100 installed.
The ED600 makes reverse osmosis water as you pour it instead of storing it in a pressure tank, so it frees up cupboard space and shows water quality live on its display. Supplied, installed under your sink and commissioned for $1,100, with a 5-year warranty.

Why go tankless
Made fresh, not stored.
- No pressure tank — more room in small kitchen and apartment cupboards
- Water is filtered as you pour, so nothing sits in a tank between uses
- 1:1 pure-to-drain ratio — about 1 litre sent to the drain for every litre of filtered water
- Smart display shows water quality (TDS) and filter life in real time
- Built-in leak detection with automatic shut-off
- Twist-in cartridges for quick, clean filter changes

About the numbers
What “99.99% of over 1,000 contaminants” means.
That figure is the manufacturer’s rating for the ED600, not an independent lab test of your water. Here is what independent research says about reverse osmosis.
- US EPA researchers found reverse osmosis membranes were typically more than 90% effective across a wide range of PFAS, including shorter-chain types that carbon handles less well.
- A 2025 Duke University study of 89 home filters found under-sink reverse osmosis and two-stage filters reduced PFAS by 94% or more.
- Sydney’s tap water already meets the Australian Drinking Water Guidelines. Reverse osmosis is extra protection and better taste, not a fix for unsafe water.
- Real-world results depend on your water and on changing cartridges on schedule — which is why we service what we install.
Tankless questions
What Sydney customers ask us.
How much does tankless reverse osmosis cost in Sydney?
The ED600 tankless system is $1,100 supplied, installed and commissioned, including GST and fittings, with a 5-year warranty. You get the fixed price on the phone before we visit.
Is tankless better than a reverse osmosis system with a tank?
Not better at filtering — both use a reverse osmosis membrane. Tankless suits small cupboards and people who want water made fresh on demand with a live water-quality display. If budget matters more than space, our 6 Stage tank system is $649 installed.
Does the tankless system need power?
Yes. Tankless reverse osmosis uses a built-in pump and display, so it needs a power point in or near the sink cupboard. We check this when you book.
Does tankless reverse osmosis remove PFAS and fluoride?
Reverse osmosis is the most thorough home treatment for both. US EPA research found reverse osmosis membranes typically more than 90% effective across a wide range of PFAS, including shorter-chain types.
