1. Introduction
This manual provides essential information for the safe and efficient installation, operation, and maintenance of your Neo-Pure 3.2 Gallon Reverse Osmosis (RO) Storage Tank. Please read all instructions carefully before proceeding with installation or use. Retain this manual for future reference.
2. Product Overview
The Neo-Pure 3.2 Gallon Reverse Osmosis Storage Tank is designed to store purified water from your RO filtration system. It features a durable white powder-coated stainless steel exterior and internal components engineered for water purity and longevity.
Key Features:
- Stainless Steel Water Connection: Ensures durability and corrosion resistance.
- High-Grade Chlorobutyl Diaphragm: Post-cured for enhanced performance and long-term reliability, ensuring water remains tasteless and odorless.
- Virgin Polypropylene Liner: Prevents water contact with the tank's metal shell, maintaining water quality.
- Plastic Tank Stand: Included for stable placement.
- CE Approved & BPA Free: Meets safety and quality standards.
Components:
The Neo-Pure RO Storage Tank consists of an outer shell, an internal water storage compartment with a virgin polypropylene liner, a chlorobutyl diaphragm, and an air bladder. A stainless steel water connection is located at the top, and an air valve for pre-charge pressure adjustment is at the bottom.

3. Setup and Installation
Proper installation is crucial for the optimal performance of your RO storage tank. This tank is designed for under-sink installation as part of a reverse osmosis system.
Unboxing:
Carefully open the packaging and remove the tank and its accessories. Inspect for any visible damage. The tank stand is included and should be attached to the bottom of the tank for stability.

Pre-Charge Pressure Check:
The tank comes pre-charged with air. It is recommended to verify the air pressure before installation. The factory pre-charge is typically 6.5 psi (0.45 bar). Use a low-pressure tire gauge (dial type recommended) to check the pressure at the air valve located at the bottom of the tank. Adjust if necessary using a bicycle pump.
Connecting to the RO System:
- Ensure all components of your RO system are clean and ready for connection.
- Apply thread sealant tape (not included) to the threads of the stainless steel water connection on top of the tank.
- Connect the tank to the RO system's post-filter line using appropriate fittings (typically a 1/4" MNPT connection). Do not overtighten.
- Place the tank on its plastic stand in the desired under-sink location.
- Slowly turn on the water supply to the RO system and check for leaks at all connections.
- Allow the tank to fill completely, then drain it once or twice to flush out any manufacturing residues before consuming water.

4. Operating Instructions
Once installed and flushed, the Neo-Pure RO Storage Tank operates automatically in conjunction with your reverse osmosis system. The tank stores purified water, and the internal air bladder provides pressure to dispense water when the RO faucet is opened.
- The tank will fill gradually as the RO membrane purifies water.
- When you open your RO faucet, the stored water will be dispensed under pressure.
- The RO system will automatically begin refilling the tank once the pressure drops below a certain level.
5. Maintenance
Regular maintenance ensures the longevity and performance of your RO storage tank and the quality of your drinking water.
- Annual Pressure Check: Check the air pre-charge pressure annually. If the pressure is too low, the tank will not dispense water effectively. The recommended pre-charge is 6.5 psi (0.45 bar) when the tank is empty.
- Sanitization: Inspect and sanitize the tank regularly by qualified personnel, especially during filter changes or if water quality issues arise.
- Leak Inspection: Periodically check all connections for leaks. Address any leaks immediately to prevent water damage.
- Tank Replacement: While durable, RO tanks have a lifespan. If you notice a significant drop in water pressure from the faucet, or if the tank feels heavy even when empty (indicating a ruptured bladder), it may be time for a replacement.
6. Troubleshooting
Here are some common issues and their potential solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Low water flow from RO faucet | Low air pre-charge in tank; clogged filters; faulty RO membrane. | Check and adjust tank air pressure (6.5 psi empty); replace filters; replace RO membrane. |
| No water from RO faucet | Tank is empty; no water supply to RO system; completely depleted air charge. | Allow time for tank to fill; check water supply valves; check and adjust tank air pressure. |
| Water tastes or smells bad | Contaminated post-filter or tank; old water in tank. | Replace post-filters; sanitize the tank; ensure regular water usage. |
| Water leaking from tank connections | Loose fittings; damaged O-rings or thread sealant. | Tighten connections; replace O-rings or reapply thread sealant. |
