Clean drinking water is no longer a luxury. Many Australian households are turning to reverse osmosis systems to remove chlorine, sediment, heavy metals, and other contaminants directly at the kitchen tap.
Unlike jug filters or basic systems, RO filtration delivers a much higher level of purification. It is installed neatly under your sink and provides consistent, high quality drinking water without relying on bottled water.
An under sink reverse osmosis system is compact but includes several key components. These are installed neatly within your kitchen cabinet.
The system is designed to fit within standard Australian cabinetry without disrupting your kitchen layout.
Professional installation ensures the system performs correctly and complies with Australian plumbing standards.
The installer connects the system to your cold water line using a secure valve. This allows water to flow into the filtration system without affecting your main tap performance.
A drain line is installed to remove waste water produced during the filtration process. This is typically connected to your sink drain pipe.
The filtration unit is mounted securely inside your cabinet wall or base. This keeps everything stable, accessible, and tidy.
The storage tank is positioned inside the cabinet. This tank holds filtered water so it is instantly available when you turn on the tap.
A small, separate tap is installed on your sink or benchtop. This is used specifically for filtered drinking water.
The installer flushes the system, checks all connections, and ensures water pressure and flow are correct.
Most under sink RO systems can be installed within 2 to 3 hours.
Time can vary depending on:
Professional installers ensure everything is done efficiently and correctly the first time.
While some systems are sold as DIY, proper installation is critical for performance and reliability.
This is why Great Water Filters focuses on professionally installed systems.
Not all RO systems are built the same. Choosing the right system depends on your water quality, household size, and expectations.
ES2 suits smaller households or basic drinking water needs. It provides solid filtration but with lower capacity.
ES3 offers a stronger balance of filtration and flow. Ideal for families wanting consistent, reliable drinking water.
For customers wanting more than just drinking water, the ES5Q system provides filtration across the entire home. While not an RO system, it protects plumbing, appliances, and delivers clean water at every tap.
No. Installers use proper tools and methods to safely install the tap without damaging your sink or benchtop.
Filters and membranes need periodic replacement. Most systems require servicing every 6 to 12 months.
RO systems do produce some waste water, but modern systems are far more efficient than older models.
Many people start with jug filters or bottled water but quickly realise the limitations.
RO systems provide a more reliable and consistent solution for clean drinking water at home.
A properly installed RO system gives you peace of mind every time you turn on your tap.
No guesswork. No ongoing hassle. Just clean, filtered water ready when you need it.
