| Tank Model | Dry Weight (Empty) | Approx. Water Weight | Total Weight (Full) |
| 12 Litre | ~4.0 kg | + 8.0 kg | ~12.0 kg |
| 24 Litre | ~6.5 kg | + 16.0 kg | ~22.5 kg |
| 40 Litre | ~9.8 kg | + 28.0 kg | ~37.8 kg |
| 74 Litre | ~14.5 kg | + 50.0 kg | ~64.5 kg |
For the 12L & 24L Models: Most kitchen cupboards can handle these weights (12–23 kg) on the base floor. However, do not place a full 24L tank on a middle shelf without reinforcing it, as the shelf may bow or collapse over time.
For the 40L & 74L Models: These are very heavy (up to 65 kg). They should always be placed on a solid concrete floor or a reinforced steel stand.
Pressure Matters: If the customer’s RO system has a high-pressure pump, the tank might hold slightly more water than listed, making it even heavier. Always calculate for a “worst-case” maximum weight.
| Tank Size | Recommended Air Pressure (Empty) | Maximum Working Pressure |
| 12 Litre | 0.45 bar (approx. 7 PSI) | 6.9 bar (100 PSI) |
| 24 Litre | 0.45 bar (approx. 7 PSI) | 6.9 bar (100 PSI) |
| 40 Litre | 0.50 bar (approx. 8 PSI) | 6.9 bar (100 PSI) |
| 74 Litre | 0.55 bar (approx. 8 PSI) | 6.9 bar (100 PSI) |
Isolate & Empty: Turn off the water supply to the RO system and open the RO faucet until the water stops flowing completely. This ensures there is no back-pressure from the water.
Locate the Valve: On the side or bottom of the stainless steel tank, there is a small plastic cap. Unscrew it to reveal a standard Schrader Valve (exactly like a car or bicycle tire valve).
Check Pressure: Use a low-pressure digital gauge. If it reads $0$, the bladder has lost its charge.
Pump Slowly: Use a manual bicycle pump or a small compressor.
Warning: Only add a few pumps at a time. Because the air chamber is small, the pressure rises very quickly.
Target: Aim for 0.45 bar. If you go over, simply bleed a little air out using the center pin of the valve.
