01Problem & Solution
Treated Water Needs Storing
Problem
Production on Demand Cannot Keep Up
Reverse osmosis systems produce water drop by drop. Without a tank you cannot draw water from the tap at a useful rate, and in an unsuitable vessel contact between the water and the air can create a hygiene problem.
Solution
Sealed, Pressurised Storage
The 12 Litre Water Treatment Tank collects treated water in a sealed, pressurised vessel. When the tap is opened it delivers the water under pressure, and its lidless, air-free construction preserves water quality.

05How It Works
How Does the 12 Litre Water Treatment Tank Work?
The System Produces Water
The treatment system slowly produces water that has passed through the filter and membrane stages.
The Tank Fills
The treated water is transferred to the tank and begins to collect inside the sealed vessel.
Pressure Builds
As the water fills, the air inside the tank is compressed and the stored water is held under pressure.
Water Is Drawn from the Tap
When the tap is opened, the pressure in the tank pushes the water out and gives an easy flow.
The System Refills It
As the tank empties, the system starts automatically and refills the store.
06Making the Right Choice
8 Litres or 12 Litres?
When choosing the 12 Litre Water Treatment Tank, consider consumption, cabinet space and compatibility with the system.
Daily Consumption
For larger families 12 litres is more comfortable; for a single person or a couple, 8 litres may be enough.
Cabinet Space
Measure the space under the worktop; in narrow cabinets a smaller tank is the better choice.
System Compatibility
The connection size and the system’s production capacity must suit the tank.
Where It Is Used
For heavy use such as cafés and restaurants, industrial 40 or 80 litre tanks are recommended.
07Maintenance and Use
Notes That Keep It Performing
- If the flow from the tap has weakened, check the tank’s air pre-charge.
- After a long period without use, we recommend draining the tank and refreshing the water.
- The tank should be placed upright and secure, where it cannot be knocked.
- Replacing the filters on time helps preserve the quality of the water stored in the tank.
08Frequently Asked Questions
Common Questions
What does the 12 Litre Water Treatment Tank do?
It stores the clean water the treatment system produces and delivers it under pressure when the tap is opened. So even though the system produces slowly, enough water is ready when you need it.
Does the tank treat the water?
No. The filter and membrane stages do the treatment; the tank only stores the treated water hygienically and provides pressure.
Why does the tank have no lid?
The tank is made without a lid to preserve the quality of the treated water. A sealed construction with no air contact helps prevent bacterial growth.
Does the tank really hold 12 litres?
Because the tank works under pressure, the usable amount of water inside it varies with the system’s inlet pressure and the tank’s air pre-charge. This is simply how pressure tanks work.
Is it compatible with my existing system?
It is designed for use with domestic under-sink treatment systems. Before replacing, we recommend checking your connection size and the space under your worktop.
