01Problem & Solution
Storing Clean Water in a Tight Space
Problem

05How It Works
How Does the 8 Litre Water Treatment Tank Work?
Treated Water Inlet
Clean water from the domestic under-sink system is transferred to the tank for storage.
Sealed Pressurised Storage
The water is collected inside a sealed body against the tank’s internal air pressure, with no contact with air.
Delivery Under Pressure
When the tap is opened, the tank’s internal air pressure pushes the water quickly to the treated-water faucet.
Automatic Refilling
As the tank depletes the system keeps producing and refills it, so water is always ready.
An Uninterrupted Cycle
The storage and refilling cycle runs continuously, meeting the household’s clean water needs throughout the day.
06Making the Right Choice
What Decides the Right Tank
The 8 Litre Water Treatment Tank is the most practical option once household size and installation space are assessed correctly.
Household Size
It suits households of one to three; larger families should choose the 12 litre tank.
System Compatibility
Matching your domestic reverse osmosis system’s connections matters for correct filling.
Installation Space
Its compact 20 × 20 × 35 cm dimensions fit comfortably into even the narrowest under-sink cabinets.
Connection Type
The standard 1/4 inch connection matches common domestic tubing sizes easily.
07Maintenance and Use
Notes That Keep It Performing
- Pressure tanks can lose 1–2 PSI of air a year; check the air pressure every six months and top it back up to 7 PSI with a bicycle pump if needed.
- With a 75 GPD membrane it fills in about 40 minutes; if that takes more than an hour, the pre-filters may be clogged or the mains pressure may have dropped.
- Check the connection fitting periodically and keep the seal sound.
- Using the stored water regularly helps keep it fresh and hygienic.
08Frequently Asked Questions
Common Questions
How many people is the 8 Litre Water Treatment Tank enough for?
Roughly 5–6 litres of the labelled capacity is usable water. That meets the daily drinking and cooking needs of a household of one to three. Larger households should choose the 12 litre tank.
How long does the tank take to fill?
With a 75 GPD membrane, about 40 minutes. If it takes more than an hour, the pre-filters are clogged or the mains pressure has dropped, and it should be checked.
Does the tank lose air over time?
Yes, pressure tanks can lose 1–2 PSI a year. Check the air pressure every six months and top it back up to 7 PSI with a bicycle pump if needed. Doing so protects both the tank’s life and its performance.
Is there any contact between water and air?
No. The sealed, pressurised construction keeps the water out of contact with air, which prevents bacterial growth and preserves the hygiene of the stored water.
How long is the warranty?
It is covered by a 2-year warranty. Its corrosion-resistant metal body gives long, dependable service.
