Description

The 3.2 Gallon (11 L) Reverse Osmosis Storage Tank is a premium water storage tank designed for residential reverse osmosis (RO) drinking water systems. Manufactured from high-durability polypropylene composite with a food-grade polypropylene liner and post-cured chlorobutyl rubber diaphragm, it provides safe, clean, and odour-free water storage while delivering a consistent flow of purified water to your drinking faucet.

Unlike traditional steel storage tanks, this corrosion-resistant plastic tank will not rust, chip, peel, or dent, making it ideal for damp under-sink environments. Compatible with approximately 99% of residential reverse osmosis systems, it features a standard ¼″ Male NPT connection for quick and easy installation.

Installation:

Install the storage tank in a clean, level location beneath the sink and connect it using the standard ¼″ Male NPT fitting. Ensure the tank pre-charge pressure is maintained between 5 and 7 PSI when empty for optimum performance. Check all fittings for leaks after installation and sanitise the system according to the RO system manufacturer’s recommendations before use.

Advantages of Plastic vs Steel RO Tanks:

• Rust-proof construction: Will not corrode in damp under-sink environments.
• Lightweight design: Easier to transport and install than steel tanks.
• Dent and impact resistant: More durable during installation and everyday use.
• No peeling paint: Maintains a clean appearance throughout its service life.
• Improved water quality: Food-grade liner prevents water from contacting raw metal, helping maintain fresh taste and odour.
